121 * Tue Nov 3 2009 : Version 1.0.103
122 - Dont use vacuuming on persistent databases
123 - Michael A : transaction updates to persistent databases
124 - Dont activate service automatically when installing the RPM. Leave this to the admin.
125 - Create a child process to send all log messages to, to prevent a hung/slow syslogd
126 from blocking the main daemon. In this case, discard log messages instead and let the child
128 - Michael A: updates to log messages
129 * Thu Oct 29 2009 : Version 1.0.102
130 - Wolfgang: fix for the vacuuming code
131 - Wolfgang: stronger tests for persistent database filename tests
132 - Improve the log message when we refuse to startup since wbinfo -t fails
133 to make it easier to spot in the log.
134 - Update the uptime command output and the man page to indicate that
135 "time since last ..." if from either the last recovery OR the last failover
136 - Michael A: transaction updates
137 * Wed Oct 28 2009 : Version 1.0.101
138 - create a separate context for non-monitoring events so they dont interfere with the monitor event
139 - make sure to return status 0 in teh callback when we abort an event
140 * Wed Oct 28 2009 : Version 1.0.100
141 - Change eventscript handling to allow EventScriptTimeout for each individual script instead of for all scripts as a whole.
142 - Enhanced logging from the eventscripts, log the name and the duration for each script as it finishes.
143 - Add a check to use wbinfo -t for the startup event of samba
144 - TEMP: allow clients to attach to databases even when teh node is in recovery mode
145 - dont run the monitor event as frequently after an event has failed
146 - DEBUG: in the eventloops, check the local time and warn if the time changes backward or rapidly forward
147 - From Metze, fix a bug where recovery master becoming unhealthy did not trigger an ip failover.
148 - Disable the multipath script by default
149 - Automatically re-activate the reclock checking if the reclock file is specified at runtime. Update manpage to reflect this.
150 - Add a mechanism where samba can register a SRVID and if samba unexpectedly disconnects, a message will be broadcasted to all other samba daemons.
151 - Log the pstree on hung scripts to a file in /tmp isntead of /var/log/messages
152 - change ban count before unhealthy/banned to 10
153 * Thu Oct 22 2009 : Version 1.0.99
154 - Fix a SEGV in the new db priority code.
155 - From Wolfgang : eliminate a ctdb_fatal() if there is a dmaster violation detected.
156 - During testing we often add/delete eventscripts at runtime. This could cause an eventscript to fail and mark the node unhealthy if an eventscript was deleted while we were listing the names. Handle the errorcode and make sure the node does not becomne unhealthy in this case.
157 - Lower the debuglevel for the messages when ctdb creates a filedescruiptor so we dont spam the logs with these messages.
158 - Dont have the RPM automatically restart ctdb
159 - Volker : add a missing transaction_cancel() in the handling of persistent databases
160 - Treat interfaces with the anme ethX* as bond devices in 10.interfaces so we do the correct test for if they are up or not.
161 * Tue Oct 20 2009 : Version 1.0.98
162 - Fix for the vacuuming database from Wolfgang M
163 - Create a directory where the test framework can put temporary overrides
164 to variables and functions.
165 - Wait a lot longer before shutting down the node when the reclock file
166 is incorrectly configured, and log where it is configured.
167 - Try to avoid running the "monitor" event when databases are frozen.
168 - Add logging for every time we create a filedescriptor so we can trap
170 * Thu Oct 14 2009 : Version 1.0.97
171 - From martins : update onnode.
172 Update onnode to allow specifying an alternative nodes file from
173 the command line and also to be able to specify hostnames on the
175 onnode host1,host2,...
176 * Tue Oct 13 2009 : Version 1.0.96
177 - Add more debugging output when eventscripts have trouble. Print a
178 "pstree -p" to the log when scripts have hung.
179 - Update the initscript, only print the "No reclock file used" warning
180 when we do "service ctdb start", dont also print them for all other
182 - When changing between unhealthy/healthy state, push a request to the
183 recovery master to perform an ip reallocation instead of waiting for the
184 recovery master to pull and check the state change.
185 - Fix a bug in the new db-priority handling where a pre-.95 recovery master
186 could no longer lock the databases on a post-.95 daemon.
187 - Always create the nfs state directories during the "monitor" event.
188 This makes it easier to configure and enable nfs at runtime.
189 - From Volker, forward-port a simper deadlock avoiding patch from the 1.0.82
190 branch. This is a simpler versionof the "db priority lock order" patch
191 that went into 1.0.95, and will be kept for a few versions until samba
192 has been updated to use the functionality from 1.0.95.
193 * Mon Oct 12 2009 : Version 1.0.95
194 - Add database priorities. Allow samba to set the priority of databases
195 and lock the databases in priority order during recovery
196 to avoid a deadlock when samba locks one database then blocks indefinitely
197 while waiting for the second databaso to become locked.
198 - Be aggressive and ban nodes where the recovery transaction start call
200 * Thu Oct 10 2009 : Version 1.0.94
201 - Be very aggressive and quickly ban nodes that can not freeze their databases
202 * Tue Oct 8 2009 : Version 1.0.93
203 - When adding an ip, make sure to update this assignment on all nodes
204 so it wont show up as -1 on other nodes.
205 - When adding an ip and immediately deleting it, it was possible that
206 the daemon would crash accessing already freed memory.
207 Readjust the memory hierarchy so the destructors are called in the right order.
208 - Add a handshake to the recovery daemon to eliminate some rare cases where
209 addip/delip might cause a recovery to occur.
210 - updated onnode documenation from Martin S
211 - Updates to the natgw eventscript to allow disabling natgw at runtime
212 * Fri Oct 2 2009 : Version 1.0.92
213 - Test updates and merge from martin
214 - Add notification for "startup"
215 - Add documentation for notification
216 - from martin, a fix for restarting vsftpd in the eventscript
217 * Tue Sep 29 2009 : Version 1.0.91
218 - New vacuum and repack design from Wolgang Mueller.
219 - Add a new eventscript 01.reclock that will first mark a node unhealthy and later ban the node if the reclock file can not be accessed.
220 - Add machinereadable output to the ctdb getreclock command
221 - merge transaction updates from Michael Adam
222 - In the new banning code, reset the culprit count to 0 for all nodes that could successfully compelte a full recovery.
223 - dont mark the recovery master as a ban culprit because a node in the cluster needs a recovery. this happens naturally when using ctdb recover command so dont make this cause a node to be banned.
224 * Sat Sep 12 2009 : Version 1.0.90
225 - Be more forgiving for eventscripts that hang during startup
226 - Fix for a banning bug in the new banning logic
227 * Thu Sep 3 2009 : Version 1.0.89
228 - Make it possible to manage winbind independently of samba.
229 - Add new prototype banning code
230 - Overwrite the vsftpd state file instead of appending. This eliminates
231 annoying errors in the log.
232 - Redirect some iptables commands to dev null
233 - From Michael A, explicitely set the broadcast when we takeover a public ip
234 - Remove a reclock file check we no longer need
235 - Skip any persistent database files ending in .bak
236 * Mon Aug 17 2009 : Version 1.0.88
237 - Add a new state for eventscripts : DISABLED.
238 Add two new commands "ctdb enablescript/disablescript" to enable/disable
239 eventscripts at runtime.

247 at runtime. Add two new commands
248 "ctdb setlmasterrole/setrecmasterrole on/off"
249 - Make it possible to enable/disable the natgw feature at runtime. Add
250 the command "ctdb setnatgwstate on/off"
251 * Fri Jul 17 2009 : Version 1.0.87
252 - Add a new event "stopped" that is called when a node is stopped.
253 - Documentation of the STOPPED flag and the stop/continue commands
254 - Make it possible to start a node in STOPPED mode.
255 - Add a new node flag : STOPPED and commands "ctdb stop" "ctdb continue"
256 These commands are similar to "diasble/enable" but will also remove the node from the vnnmap, while disable only fails all ip addresses over.
257 - tests for NFS , CIFS by martins
258 - major updates to the init script by martins
259 - Send gratious arps with a 1.1 second stride instead of a 1 second stride to workaround interesting "features" of common linux stacks.
260 - Various test enhancements from martins:
261 - additional other tests
262 - add tests for grat arp generation, ping during failover, ssh and failover
263 - New/updated tcp tickle tests and supprot functions
264 - provide better debugging when a test fails
265 - make ctdbd restarts more reliable in the tests
266 - update the "wait bar" to make the wait progress in tests more obvious
268 - when dispatching a message to a handler, make the message a real talloc object so that we can reparent the object in the tallic hierarchy.
269 - document the ipreallocate command
270 - Updates to enable/disable to use the ipreallocate command to block until the following ipreallocation has completed.
271 - Update the main daemon and the tools to allow debug level to be a string instead of an integer.
272 - Update the sysconfig file to show using string literals instead of numeric values for the debuglevels used.
273 - If no debuglevel is specific, make "ctdb setdebug" show the available options.
274 - When trying to allocate network packets, add explicit checks if the network transport has been shutdown before trying and failing, to make log messages easier to read. Add this extra check and logging to every plave packets are allocated.
275 * Tue Jun 30 2009 : Version 1.0.86
276 - Do not access the reclock at all if VerifyRecoveryLock is zero, not even try to probe it.
277 - Allow setting the reclock file as "", which means that no reclock file at all should be used.
278 - Document that a reclock file is no longer required, but that it is dangerous.
279 - Add a control that can be used to set/clear/change the reclock file in the daemon during runtime.
280 - Update the recovery daemon to poll whether a reclock file should be sued and if so which file at runtime in each monitoring cycle.
281 - Automatically disable VerifyRecoveryLock everytime a user changes the location of the reclock file.
282 - do not allow the VerifyRecoveryLock to be set using ctdb setvar if there is no recovery lock file specified.
283 - Add two commands "ctdb getreclock" and "ctdb setreclock" to modify the reclock file.
284 * Tue Jun 23 2009 : Version 1.0.85
285 - From William Jojo : Dont use getopt on AIX
286 - Make it possible to use "ctdb listnodes" also when the daemon is not running
287 - Provide machinereadable output to "ctdb listnodes"
288 - Dont list DELETED nodes in the ctdb listnodes output
289 - Try to avoid causing a recovery for the average case when adding/deleting/moving an ip
290 - When banning a node, drop the IPs on that node only and not all nodes.
291 - Add tests for NFS and CIFS tickles
292 - Rename 99.routing to 11.routing so it executes before NFS and LVS scripts
293 - Increase the default timeout before we deem an unresponsive recovery daemon hung and shutdown
294 - Reduce the reclock timout to 5 seconds
295 - Spawn a child process in the recovery daemon ot check the reclock file to
296 avoid blocking the process if the underlying filesystem is unresponsive
297 - fix for filedescriptor leak when a child process timesout
298 - Dont log errors if waitpid() returns -1
299 - Onnode updates by Martins
300 - Test and initscript cleanups from Martin S

305 - Hide all deleted nodes from ctdb output.
306 - Lower the loglevel on some eventscript related items
307 - Dont queue packets to deleted nodes
308 - When building initial vnnmap, ignode any nonexisting nodes
309 - Add a new nodestate : DELETED that is used when deleting a node from an
311 - dont remove the ctdb socket when shutting down. This prevents a race in the
312 initscripts when restarting ctdb quickly after stopping it.
313 - TDB nesting reworked.
314 - Remove obsolete ipmux
315 - From Flavio Carmo Junior: Add eventscript and documentation for ClamAV antivirus engine
316 - From Sumit Bose: fix the regex in the test to handle the new ctdb
317 statistics output that was recently added.
318 - change the socket type we use for grauitious arps from the obsolete
319 AF_INET/SOCK_PACKET to instead use PF_PACKET/SOCK_RAW.
320 - Check return codes for some functions, from Sumit Bose, based on codereview by Jim Meyering.

324 - Remove error messages about missing /var/log/log.ctdb file from ctdb_diagnostics.sh from christian Ambach
325 - Additional error logs if hte eventscript switching from dameon to client mode fails.
326 - track how long it takes for ctdbd and the recovery daemon to perform the rec-lock fcntl() lock attemt and show this in the ctdb statistics output.
327 * Thu May 14 2009 : Version 1.0.82
328 - Update the "ctdb lvsmaster" command to return -1 on error.
329 - Add a -Y flag to "ctdb lvsmaster"
330 - RHEL5 apache leaks semaphores when crashing. Add semaphore cleanup to the
331 41.httpd eventscript and try to restart apache when it has crashed.
332 - Fixes to some tests
333 - Add a -o option to "onnode" which will redirect all stdout to a file for
335 - Add a natgw and a lvs node specifier to onnode so that we can use
337 - Assign the natgw address to lo instead of the private network so it can also
338 be used where private and public networks are the same.
339 - Add GPL boilerplates to two missing scripts.
340 - Change the natgw prefix NATGW_ to CTDB_NATGW_
341 * Fri May 8 2009 : Version 1.0.81
342 - use smbstatus -np instead of smbstatus -n in the 50.samba eventscript
343 since this avoids performing an expensive traverse on the locking and brlock
345 - make ctdb automatically terminate all traverse child processes clusterwide
346 associated to a client application that terminates before the traversal is
348 - From Sumit Bose : fixes to AC_INIT handling.
349 - From Michael Adam, add Tridge's "ping_pong" tool the the ctdb distro since
350 this is very useful for testing the backend filesystem.
351 - From Sumit bose, add support for additional 64 bit platforms.
352 - Add a link from the webpage to Michael Adams SambaXP paper on CTDB.
353 * Fri May 1 2009 : Version 1.0.80
354 - change init shutdown level to 01 for ctdb so it stops before any of the other services
355 - if we can not pull a database from a remote node during recovery, mark that node as a culprit so it becomes banned
356 - increase the loglevel when we volunteer to drop all ip addresses after beeing in recovery mode for too long. Make this timeout tuneable with "RecoveryDropAllIPs" and have it default to 60 seconds
357 - Add a new flag TDB_NO_NESTING to the tdb layer to prevent nested transactions which ctdb does not use and does not expect. Have ctdb set this flag to prevent nested transactions from occuring.
358 - dont unconditionally kill off ctdb and restrat it on "service ctdb start". Fail "service ctdb start" with an error if ctdb is already running.
359 - Add a new tunable "VerifyRecoveryLock" that can be set to 0 to prevent the main ctdb daemon to verify that the recovery master has locked the reclock file correctly before allowing it to set the recovery mode to active.
360 - fix a cosmetic bug with ctdb statistics where certain counters could become negative.
361 * Wed Apr 8 2009 : Version 1.0.79
362 - From Mathieu Parent: add a ctdb pkgconfig file
364 - add a funciton remove_ip to safely remove an ip from an interface, taking care to workaround an issue with linux alias interfaces.
365 - Update the natgw eventscript to use the safe remove_ip() function
366 - fix a bug in the eventscript child process that would cause the socket to be removed.
367 - dont verify nodemap on banned nodes during cluster monitoring
368 - Update the dodgy SeqnumInterval to have ms resolution
369 * Tue Mar 31 2009 : Version 1.0.78
370 - Add a notify mechanism so we can send snmptraps/email to external management systems when the node becomes unhealthy
371 - include 11.natgw eventscript in thew install so that the NATGW feature works
372 * Tue Mar 31 2009 : Version 1.0.77
373 - Update the 99.routing eventscript to also try to add the routes (back) during a releaseip event. Similar to the reasons why we must add addresses back during releaseip in 10.interfaces
374 * Wed Mar 24 2009 : Version 1.0.76
375 - Add a debugging command "xpnn" which can print the pnn of the node even when ctdbd is not running.
376 - Redo the NATGW implementation to allow multiple disjoing NATGW groups in the same cluster.
377 * Tue Mar 24 2009 : Version 1.0.75
378 - Various updates to LVS
379 - Fix a bug in the killtcp control where we did not set the port correctly
380 - add a new "ctdb scriptstatus" command that shows the status of the eventrscripts.
381 * Mon Mar 16 2009 : Version 1.0.74
382 - Fixes to AIX from C Cowan.
383 - Fixes to ctdb_diagnostics so we collect correct GPFS data
384 - Fixes to the net conf list command in ctdb_diagnostics
385 - Check the static-routes file IFF it exists in ctdb_diagnostics
386 * Wed Mar 4 2009 : Version 1.0.73
387 - Add possibility to disable the check of shares for NFS and Samba
388 - From Sumit Bose, fix dependencies so make -j works
389 * Wed Feb 18 2009 : Version 1.0.72
390 - Updates to test scripts by martin s
391 - Adding a COPYING file
392 - Use netstat to check for services and ports and fallback to netcat
393 only if netstat is unavailable.
394 * Mon Feb 2 2009 : Version 1.0.71
395 - Additional ipv6 fixes from Michael Adams
396 * Fri Jan 16 2009 : Version 1.0.70
397 - IPv6 support is completed. this is backward compatible with ipv4-only
398 systems. To use IPv6 with samba and ctdb you need current GIT of samba 3.3
399 or michael adams samba-ctdeb branch.
400 - Many enhancements to the build system and scripts to make it more SUSE
401 friendly by Michael Adams.
402 - Change of how the naming of the package is structured. We are now
403 using "1.0.70" as a release and "-1" as the revision instead of as
404 previously using "1.0" as release and ".70" as the revision.
406 * Thu Dec 18 2008 : Version 1.0.69
407 - Various fixes to scripts by M Adam
408 - Dont call ctdb_fatal() when the transport is down during shutdown
409 * Fri Dec 12 2008 : Version 1.0.68
410 - Fixes for monitoring of interfaces status from Michael Adam.
411 - Use -q instead of >/dev/null for grep to enhance readability of the
412 scripts from Michael Adam.
413 - Update to the "ctdb recover" command. This command now block until the
414 has completed. This makes it much easier to use in scripts and avoids
415 the common workaround :
417 ... loop while waiting for recovery completes ...
419 - Add a CTDB_TIMEOUT variable. If set, this variable provides an automatic
420 timeout for "ctdb <command>", similar to using -T <timeout>
421 - Set a unique errorcode for "ctdb <command>" when it terminates due to a
422 timeout so that scripts can distinguish between a hung command and what was
424 - Update "ctdb ban/unban" so that if the cluster is in recovery these commands
425 blocks and waits until after recovery is complete before the perform the
426 ban/unban operation. This is necessary since the recovery process can cause
427 nodes to become automatically unbanned.
428 - Update "ctdb ban/unban" to block until the recovery that will follow shortly
429 after this command has completed.
430 This makes it much easier to use in scripts and avoids the common
433 ... loop while waiting for recovery completes ...
435 - Bugfix for the new flags handling in 1.0.67. Abort and restart monitoring
436 if we failed to get proper nodemaps from a remote node instead of
437 dereferencing a null pointer.
438 - If ctdbd was explicitely started with the '--socket' argument, make
439 ctdbd automatically set CTDB_SOCKET to the specified argument.
440 This ensures that eventscripts spawned by the ctdb daemon will default to
441 using the same socket and talk to the correct daemon.
442 This primarily affects running multiple daemons on the same host and where
443 you want each instance of ctdb daemons have their eventscripts talk to the
445 - Update "ctdb ping" to return an error code if the ping fail so that it
446 can be used in scripts.
447 - Update to how to synchronize management of node flags across the cluster.
448 * Thu Dec 3 2008 : Version 1.0.67
449 - Add a document describing the recovery process.
450 - Fix a bug in "ctdb setdebug" where it would refuse to set a negative
452 - Print the list of literals for debug names if an invalid one was given
454 - Redesign how "ctdb reloadnodes" works and reduce the amont of tcp teardowns
455 used during this event.
456 - Make it possible to delete a public ip from all nodes at once using
458 * Mon Nov 24 2008 : Version 1.0.66
459 - Allow to change the recmaster even when we are not frozen.
460 - Remove two redundant SAMBA_CHECK variables from the sysconf example
461 - After a node failure it can take very long before some lock operations
462 ctdb needs to perform are allowed/works with gpfs again. Workaround this
463 by treating a hang/timeout as success.
464 - Dont override CTDB_BASE is fet in the shell already
465 - Always send keepalive packets regardless of whether the link is idle or not.
466 - Rewrite the disable/enable flag update logic to prevent a race between
467 "ctdb disable/enable" and the recovery daemon when updating the flags to
469 * Thu Nov 13 2008 : Version 1.0.65
470 - Update the sysconfig example: The default debug level is 2 (NOTICE) and not
472 - Add support for a CTDB_SOCKET environment variable for the ctdb command
473 line tool. If set, this overrides the default socket the ctdb tool will
475 - Add logging of high latency operations.
476 * Mon Oct 22 2008 : Version 1.0.64
477 - Add a context and a timed event so that once we have been in recovery for
478 too long we drop all public addresses.
479 * Mon Oct 20 2008 : Version 1.0.63
480 - Remove logging of "periodic cleanup ..." in 50.samba
481 - When we reload a nodes file, we must detect this and reload the file also
482 in the recovery daemon before we try to dereference somethoung beyond the end
484 * Thu Oct 16 2008 : Version 1.0.62
485 - Allow multiple eventscritps using the same prefix number.
486 It is undefined which order scripts with the same prefix will execute in.
487 * Wed Oct 15 2008 : Version 1.0.61
488 - Use "route add -net" instead of "ip route add" when adding routes in 99.routing
489 - lower the loglevel os several debug statements
490 - check the status returned from ctdb_ctrl_get_tickles() before we try to print them out to the screen.
491 - install a new eventscript 20.multipathd whoich can be used to monitor that multipath devices are healthy
492 * Wed Oct 15 2008 : Version 1.0.60
493 - Verify that nodes we try to ban/unban are reachable and print an error othervise.
494 - Update the client and server sides of TAKEIP/RELEASEIP/GETPUBLICIPS and GETNODEMAP to fall back to the old style ipv4-only controls if the new ipv4/ipv6 controls fail. This allows an ipv4/v6 enabled ctdb daemon to interoperate with earlier ipv4-only versions of the daemons.
495 - From Mathieu Parent : log debian systems log the package versions in ctdb diagnostics
496 - From Mathieu Parent : specify logdir location for debian (this patch was later reversed)
497 - From Michael Adams : allow # comments in nodes/public_addresses files
498 * Tue Oct 7 2008 : Version 1.0.59
499 - Updated "reloadnodes" logic. Instead of bouncing the entire tcp layer it is sufficient to just close and reopen all outgoing tcp connections.
500 - New eventscript 99.routing which can be used to re-attach routes to public interfaces after a takeip event. (routes may be deleted by the kernel when we release an ip)
501 - IDR tree fix from Jim Houston
502 - Better handling of critical events if the local clock is suddenly changed forward by a lot.
503 - Fix three slow memory leaks in the recovery daemon
504 - New ctdb command : ctdb recmaster which prints the pnn of the recmaster
505 - Onnode enhancements from Martin S : "healthy" and "connected" are now possible nodespecifiers
506 - From Martin S : doc fixes
507 - lowering some debug levels for some nonvital informational messages
508 - Make the daemon daemon monitoring stronger and allow ctdbd to detect a hung
510 - From C Cowan : patches to compile ipv6 under AIX
511 - zero out some structs to keep valgrind happy
512 * Wed Aug 27 2008 : Version 1.0.58
513 - revert the name change tcp_tcp_client back to tcp_control_tcp so
515 - Updates to the init script from Abhijith Das <adas@redhat.com>
516 * Mon Aug 25 2008 : Version 1.0.57
517 - initial support for IPv6
518 * Mon Aug 11 2008 : Version 1.0.56
519 - fix a memory leak in the recovery daemon.
520 * Mon Aug 11 2008 : Version 1.0.55
521 - Fix the releaseip message we seond to samba.
522 * Fri Aug 8 2008 : Version 1.0.54
523 - fix a looping error in the transaction code
524 - provide a more detailed error code for persistent store errors
525 so clients can make more intelligent choices on how to try to recover
526 * Thu Aug 7 2008 : Version 1.0.53
527 - Remove the reclock.pnn file it can cause gpfs to fail to umount
528 - New transaction code
529 * Mon Aug 4 2008 : Version 1.0.52
530 - Send an explicit gratious arp when starting sending the tcp tickles.
531 - When doing failover, issue a killtcp to non-NFS/non-CIFS clients
532 so that they fail quickly. NFS and CIFS already fail and recover
534 - Update the test scripts to handle CTRL-C to kill off the test.
535 * Mon Jul 28 2008 : Version 1.0.51
536 - Strip off the vlan tag from bond devices before we check in /proc
537 if the interface is up or not.
538 - Use testparm in the background in the scripts to allow probing
539 that the shares do exist.
540 - Fix a bug in the logging code to handle multiline entries better
541 - Rename private elements from private to private_data
542 * Fri Jul 18 2008 : Version 1.0.50
543 - Dont assume that just because we can establish a TCP connection
544 that we are actually talking to a functioning ctdb daemon.
545 So dont mark the node as CONNECTED just because the tcp handshake
547 - Dont try to set the recmaster to ourself during elections for those
548 cases we know this will fail. To remove some annoying benign but scary
549 looking entries from the log.
550 - Bugfix for eventsystem for signal handling that could cause a node to
552 * Thu Jul 17 2008 : Version 1.0.49
553 - Update the safe persistent update fix to work with unpatched samba
555 * Thu Jul 17 2008 : Version 1.0.48
556 - Update the spec file.
557 - Do not start new user-triggered eventscripts if we are already
558 inside recovery mode.
559 - Add two new controls to start/cancel a persistent update.
560 A client such as samba can use these to tell ctdbd that it will soon
561 be writing directly to the persistent database tdb file. So if
562 samba is -9ed before it has eitehr done the persistent_store or
563 canceled the operation, ctdb knows that the persistent databases
564 'may' be out of sync and therefore a full blown recovery is called for.
565 - Add two new options :
566 CTDB_SAMBA_SKIP_CONF_CHECK and CTDB_SAMBA_CHECK_PORTS that can be used
567 to override what checks to do when monitoring samba health.
568 We can no longer use the smbstatus, net or testparm commands to check
569 if samba or its config is healthy since these commands may block
570 indefinitely and thus can not be used in scripts.
571 * Fri Jul 11 2008 : Version 1.0.47
572 - Fix a double free bug where if a user striggered (ctdb eventscript)
573 hung and while the timeout handler was being processed a new user
574 triggered eventscript was started we would free state twice.
575 - Rewrite of onnode and associated documentation.
576 * Thu Jul 10 2008 : Version 1.0.46
577 - Document both the LVS:cingle-ip-address and the REMOTE-NODE:wan-accelerator
579 - Add commands "ctdb pnn", "ctdb lvs", "ctdb lvsmaster".
580 - LVS improvements. LVS is the single-ip-address mode for a ctdb cluster.
581 - Fixes to supress rpmlint warnings
583 - Change \s to [[:space:]] in some scripts. Not all RHEL5 packages come
584 with a egrep that handles \s even same version but different arch.
585 - Revert the change to NFS restart. CTDB should NOT attempt to restart
587 - Rewrite of the waitpid() patch to use the eventsystem for handling
589 * Tue Jul 8 2008 : Version 1.0.45
590 - Try to restart the nfs service if it has failed to respond 3 times in a row.
591 - waitpid() can block if the child does not respond promptly to SIGTERM.
592 ignore all SIGCHILD signals by setting SIGCHLD to SIG_DEF.
593 get rid of all calls to waitpid().
594 - make handling of eventscripts hanging more liberal.
595 only consider the script to have failed and making the node unhealthy
596 IF the eventscript terminated wiht an error
597 OR the eventscript hung 5 or more times in a row
598 * Mon Jul 7 2008 : Version 1.0.44
599 - Add a CTDB_VALGRIND option to /etc/sysconfig/ctdb to make it start
600 ctdb under valgrind. Logs go to /var/log/ctdb_valgrind.PID
601 - Add a hack to show the control opcode that caused uninitialized data
602 in the valgrind output by encoding the opcode as the line number.
603 - Initialize structures and allocated memory in various places in
604 ctdb to make it valgrind-clean and remove all valgrind errors/warnings.
605 - If/when we destroy a lockwait child, also make sure we cancel any pending transactions
606 - If a transaction_commit fails, delete/cancel any pending transactions and
607 return an error instead of calling ctdb_fatal()
608 - When running ctdb under valgrind, make sure we run it with --nosetsched and also
609 ensure that we do not use mem-mapped i/o when accessing the tdb's.
610 - zero out ctdb->freeze_handle when we free/destroy a freeze-child.
611 This prevent a heap corruption/ctdb crash bug that could trigger
612 if the freeze child times out.
613 - we dont need to explicitely thaw the databases from the recovery daemon
614 since this is done implicitely when we restore the recovery mode back to normal.
615 - track when we start and stop a recovery. Add the 'time it took to complete the
616 recovery' to the 'ctdb uptime' output.
617 Ensure by tracking the start/stop recovery timestamps that we do not
618 check that the ip allocation is consistend from inside the recovery daemon
619 while a different node (recovery master) is performing a recovery.
620 This prevent a race that could cause a full recovery to trigger if the
621 'ctdb disable/enable' commands took very long.
622 - The freeze child indicates to the master daemon that all databases are locked
623 by writing data to the pipe shared with the master daemon.
624 This write sometimes fail and thus the master daemon never notices that the databases
625 are locked cvausing long timeouts and extra recoveries.
626 Check that the write is successful and try the write again if it failed.
627 - In each node, verify that the recmaster have the right node flags for us
628 and force a push of our flags to the recmaster if wrong.
629 * Tue Jul 1 2008 : Version 1.0.43
630 - Updates and bugfixes to the specfile to keep rpmlint happy
631 - Force a global flags update after each recovery event.
632 - Verify that the recmaster agrees with our node flags and update the
634 - When writing back to the parent from a freeze-child across the pipe,
635 loop over the write in case the write failed with an error othervise
636 the parent will never be notified tha the child has completed the operation.
637 - Automatically thaw all databases when recmaster marks us as being in normal
638 mode instead of recovery mode.
639 * Fri Jun 13 2008 : Version 1.0.42
640 - When event scripts have hung/timedout more than EventScriptBanCount times
641 in a row the node will ban itself.
642 - Many updates to persistent write tests and the test scripts.
643 * Wed May 28 2008 : Version 1.0.41
644 - Reactivate the safe writes to persistent databases and solve the
645 locking issues. Locking issues are solved the only possible way,
646 by using a child process to do the writes. Expensive and slow but... .
647 * Tue May 27 2008 : Version 1.0.40
648 - Read the samba sysconfig file from the 50.samba eventscript
649 - Fix some emmory hierarchical bugs in the persistent write handling
650 * Thu May 22 2008 : Version 1.0.39
651 - Moved a CTDB_MANAGES_NFS, CTDB_MANAGES_ISCSI and CTDB_MANAGES_CSFTPD
652 into /etc/sysconfig/ctdb
653 - Lowered some debug messages to not fill the logfile with entries
654 that normally occur in the default configuration.
655 * Fri May 16 2008 : Version 1.0.38
656 - Add machine readable output support to "ctdb getmonmode"
657 - Lots of tweaks and enhancements if the event scripts are "slow"
658 - Merge from tridge: an attempt to break the chicken-and-egg deadlock that
659 net conf introduces if used from an eventscript.
660 - Enhance tickles so we can tickle an ipv6 connection.
661 - Start adding ipv6 support : create a new container to replace sockaddr_in.
662 - Add a checksum routine for ipv6/tcp
663 - When starting up ctdb, let the init script do a tdbdump on all
664 persistent databases and verify that they are good (i.e. not corrupted).
665 - Try to use "safe transactions" when writing to a persistent database
666 that was opened with the TDB_NOSYNC flag. If we can get the transaction
667 thats great, if we cant we have to write anyway since we cant block here.
668 * Mon May 12 2008 : Version 1.0.37
669 - When we shutdown ctdb we close the transport down before we run the
670 "shutdown" eventscripts. If ctdb decides to send a packet to a remote node
671 after we have shutdown the transport but before we have shutdown ctdbd
672 itself this could lead to a SEGV instead of a clean shutdown. Fix.
673 - When using the "exportfs" command to extract which NFS export directories
674 to monitor, exportfs violates the "principle of least surprise" and
675 sometimes report a single export line as two lines of text output
676 causing the monitoring to fail.
677 * Fri May 9 2008 : Version 1.0.36
678 - fix a memory corruption bug that could cause the recovery daemon to crash.
679 - fix a bug with distributing public ip addresses during recovery.
680 If the node that is the recovery master did NOT use public addresses,
681 then it assumed that no other node in the cluster used them either and
682 thus skipped the entire step of reallocating public addresses.
683 * Wed May 7 2008 : Version 1.0.35
684 - During recovery, when we define the new set of lmasters (vnnmap)
685 only consider those nodes that have the can-be-lmaster capability
686 when we create the vnnmap. unless there are no nodes available which
687 supports this capability in which case we allow the recmaster to
688 become lmaster capable (temporarily).
689 - Extend the async framework so that we can use paralell async calls
690 to controls that return data.
691 - If we do not have the "can be recmaster" capability, make sure we will
692 lose any recmaster elections, unless there are no nodes available that
693 have the capability, in which case we "take/win" the election anyway.
694 - Close and reopen the reclock pnn file at regular intervals.
695 Make it a non-fatal event if we occasionally fail to open/read/write
697 - Monitor that the recovery daemon is still running from the main ctdb
698 daemon and shutdown the main daemon when recovery daemon has terminated.
699 - Add a "ctdb getcapabilities" command to read the capabilities off a node.
700 - Define two new capabilities : can be recmaster and can be lmaster
701 and default both capabilities to YES.
702 - Log denied tcp connection attempts with DEBUG_ERR and not DEBUG_WARNING
703 * Thu Apr 24 2008 : Version 1.0.34
704 - When deleting a public ip from a node, try to migrate the ip to a different
706 - Change catdb to produce output similar to tdbdump
707 - When adding a new public ip address, if this ip does not exist yet in
708 the cluster, then grab the ip on the local node and activate it.
709 - When a node disagrees with the recmaster on WHO is the recmaster, then
710 mark that node as a recovery culprit so it will eventually become
712 - Make ctdb eventscript support the -n all argument.
713 * Thu Apr 10 2008 : Version 1.0.33
714 - Add facilities to include site local adaptations to the eventscript
715 by /etc/ctdb/rc.local which will be read by all eventscripts.
716 - Add a "ctdb version" command.
717 - Secure the domain socket with proper permissions from Chris Cowan
718 - Bugfixes for AIX from Chris Cowan
719 * Wed Apr 02 2008 : Version 1.0.32
720 - Add a control to have a node execute the eventscripts with arbitrary
721 command line arguments.
722 - Add a control "rddumpmemory" that will dump the talloc memory allocations
723 for the recovery daemon.
724 - Decorate the talloc memdump to produce better and easier memory leak
726 - Update the RHEL5 iscsi tgtd scripts to allow one iscsi target for each
728 - Add two new controls "addip/delip" that can be used to add/remove public
729 addresses to a node at runtime. After using these controls a "ctdb recover"
730 ir required to make the changes take.
731 - Fix a couple of slow memory leaks.
732 * Tue Mar 25 2008 : Version 1.0.31
733 - Add back controls to disable/enable monitoring on a node.
734 - Fix a memory leak where we used to attach CALL data to the ctdb structure
735 when performing a local call. Memory which would be lost if the call was
737 - Reduce the loglevel for the log output when someone connects to a non
738 public ip address for samba.
739 - Redo and optimize the vacuuming process to send only one control to each
740 other node containing all records to be vacuumed instead of one
741 control per node per record.
742 * Tue Mar 04 2008 : Version 1.0.30
743 - Update documentation cor new commands and tuneables
744 - Add machinereadable output to the ip,uptime and getdebug commands
745 - Add a moveip command to manually failover/failback public ips
746 - Add NoIPFallback tuneable that prevents ip address failback
747 - Use file locking inside the CFS as alternative to verify when other nodes
748 Are connected/disconnected to be able to recover from split network
749 - Add DisableWhenUnhealthy tunable
750 - Add CTDB_START_AS_DISABLED sysconfig param
751 - Add --start-as-disabled flag to ctdb
752 - Add ability to monitor for OOM condition

754 - Add a new command to make expansion of an existing cluster easier
755 - Fix bug with references to freed objects in the ctdb structure
756 - Propagate debuglevel changes to the recovery daemon
757 - Merge patches to event scripts from Mathieu Parent :
758 - MP: Simulate "service" on systems which do not provide this tool
759 - MP: Set correct permissions for events.d/README
760 - Add nice helper functions to start/stop nfs from the event scripts
761 * Fri Feb 08 2008 : Version 1.0.28
762 - Fix a problem where we tried to use ethtool on non-ethernet interfaces
763 - Warn if the ipvsadm packege is missing when LVS is used
764 - Dont use absolute pathnames in some of the event scripts
