Summary	0016411: packaging issues with ctdb
Description	ctdb package appears to have something missing for it to function properly. if you install ctdb and set it up it errors at start of the daemon with: ctdbd[5547]: CTDB starting on node ctdbd[5548]: Starting CTDBD (Version 4.9.3) as PID: 5548 ctdbd[5548]: Created PID file /var/run/ctdb/ctdbd.pid ctdbd[5548]: Removed stale socket /var/run/ctdb/ctdbd.socket ctdbd[5548]: Listening to ctdb socket /var/run/ctdb/ctdbd.socket ctdbd[5548]: Set real-time scheduler priority ctdbd[5548]: Starting event daemon /usr/libexec/ctdb/ctdb-eventd -P 5548 -S ctdbd[5548]: Set runstate to INIT (1) ctdbd[5548]: ctdb exiting with error: Failed to run init event ctdbd[5548]: ctdbd[5548]: CTDB daemon shutting down ctdb-eventd[5550]: PID 5548 gone away, exiting with no hint as to why it fails. running ctdbd thru strace gave me a clue. there is a missing folder that's causing this, so running: mkdir -p /etc/ctdb/events/legacy to create the missing legacy folder gets me a bit further. after this i get a bit further but this time it errors on: ctdbd[4472]: tdb(/var/lib/ctdb/state/persistent_health.tdb.0): tdb_open_ex: could not open file /var/lib/ctdb/state/persistent_health.tdb.0: No such file or directory so create the missing state folder: mkdir -p /var/lib/ctdb/state this now results in a daemon that starts up. But the daemon has some issue taking over the cluster IP.
Steps To Reproduce	Steps to Reproduce: 1. install ctdb 2. setup ctdb 3. try to start the daemon and watch it fail with next to no clues in log

dipsspid 2019-09-18 13:32 reporter ~0035116	The version of CTDB used is CTDBD (Version 4.9.1)

dipsspid 2019-09-23 07:34 reporter ~0035198	# cat /etc/redhat-release CentOS Linux release 7.7.1908 (Core)

dipsspid 2019-09-27 07:15 reporter ~0035249	Any news on this ? It was possible to replicate the issue ?

ailiev 2019-09-29 11:29 reporter ~0035265	I can confirm that this is reproducible using the steps from this report and also that the fixes mentioned (creating the /etc/ctdb/events/legacy and /var/lib/ctdb/state directories) helps.

dipsspid 2019-10-01 12:57 reporter ~0035282	Hi ailiev, creating the needed directory do not fix the take-over process. Is is needed to permit to ctdb to start only.

farkey_2000 2019-10-05 14:22 reporter ~0035336	I am experiencing the same problem. Adding the directories, as Ailiev suggests allows the service to start, however none of the VIP's/public addresses seem to coming up.

ailiev 2019-10-05 16:09 reporter ~0035337	dipssid, farkey_2000, this is correct. I also needed to create the /var/lib/ctdb/persistent and /var/lib/ctdb/volatile direcotries before ctdb was functional.

dipsspid 2019-10-07 07:30 reporter ~0035354	Tried to create all needed directories, the daemon starts but still the takeover process has some issues: The log report this: <cut> 2019/10/07 09:21:39.701502 ctdbd[7631]: monitor event OK - node re-enabled 2019/10/07 09:21:39.702375 ctdbd[7631]: Node became HEALTHY.

Tried to change permissions on previous create directories to 777, but no luck :( @farkey_2000: which is you experience, the suggested actions from aliev fix on your side?

dipsspid 2019-10-07 07:33 reporter ~0035355	I'm also notice that no lockfile is created.....(from ctdbd.conf , variable CTDB_RECOVERY_LOCK). Tried different location, shared storage or local storage.

farkey_2000 2019-10-09 23:16 reporter ~0035419	No all of the fixes, folder creation etc, only allows for the service to start. None of the public addresses are "pingable" or get assigned. I followed up with the SAMBA group and their response, which is the title of this bug is the back ported 4.9 version CENTOS is pushing in the repos. Which they suggest upgrading to 4.11 and the RPM is currently on FC 32. I have not tried samba this option yet. thank

dipsspid 2019-11-13 08:58 reporter ~0035683	Hello, any news on this ?

TrevorH 2019-11-13 08:59 manager ~0035684	CentOS is a rebuild of the sources used to create RHEL. We do not modify anything except to remove branding and logos. You will need to submit your request to Redhat via bugzilla.redhat.com and if/when RH accepts it and incorporates it into RHEL and releases a patched version, then CentOS will pick it up and rebuild it.
