[Bug 1439649] Re: Pacemaker unable to communicate with corosync on restart under lxc

  Thread Previous • Date Previous • • Thread Next 
After trying several corosync/pacemaker restarts without luck,
I was able to workaround this by adding an 'uidgid'
entry for hacluster:haclient:

* from /var/log/syslog:
Aug 31 18:33:18 juju-machine-3-lxc-3 corosync[901082]:  [MAIN  ] Denied connection attempt from 108:113
$ getent passwd 108
hacluster:x:108:113::/var/lib/heartbeat:/bin/false
$ getent group 113
haclient:x:113:

* add uidgid config:
# echo $'uidgid {\n  uid: hacluster\n  gid: haclient\n}' > /etc/corosync/uidgid.d/hacluster

* restart => Ok (crm status, etc)

I can't explain why other units are working ok without
this ACL addition (racing at service setup/start?).

Title:
  Pacemaker unable to communicate with corosync on restart under lxc

Status in lxc package in Ubuntu:
  Confirmed
Status in pacemaker package in Ubuntu:
  Confirmed

Bug description:
  We've seen this a few times with three node clusters, all running in
  LXC containers; pacemaker fails to restart correctly as it can't
  communicate with corosync, resulting in a down cluster.  Rebooting the
  containers resolves the issue, so suspect some sort of bad state
  either in corosync or pacemaker.
