Fixed In Version:
Doc Type: Known Issue
Doc Text:
Pacemaker continuously crashes when the fencing device name and the host name are the same. To avoid this problem, add the "fence-" prefix or the "-fence" suffix to the name of the fencing device. With the names configured like this, the cluster works without errors.

Comment 3 Fabio Massimo Di Nitto 2015-07-27 07:43:01 UTC
Skipping trough the details of the original bug, the way in which ospd is configuring fence devices causes pacemaker to crash.

The root issue is of course in pacemaker and we are working to fix it, BUT we can´t make it in time for OSP7 GA.

The problem is that OSPd is configuring fence devices with a name that matches the hostname. This makes pacemaker crash and fail.

the simplest workaround possible is to simply add a fence-* prefix or *-fence suffix when configuring stonith devices.

Without this workaround and the proper fix, it will be impossible to manage a HA OSP.

Be aware that everything will work just fine after a normal deployment because fence devices are configured after cluster has formed, but everything will explode at the first time one of the nodes is rebooted or restarted.

Moving this to A2 since we don't yet support fence device configuration with OSP-director just yet.

Comment 7 Mike Burns 2016-04-07 20:47:27 UTC
This bug did not make the OSP 8.0 release.  It is being deferred to OSP 10.

Comment 9 Fabio Massimo Di Nitto 2016-08-30 12:30:39 UTC
moving to OSP11 as part of auto-fencing implementation.

Chris, while the pacemaker bug has been fixed, we still want to have a fence-$nodename or $nodename-fence entry when creating stonith services.
