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

  Thread Previous • Date Previous • • Thread Next 
Looking at logs from bug 1491228, it would appear that the first time
that pacemaker goes to talk to the corosync daemon it gets denied. Per
upstream docs [0], if the enable-acl property isn't explicitly enabled,
then any user in the haclient group should have access. Since the
hacluster charm doesn't explicitly enable the acl, I'd expect pacemaker
to be running under the haclient/hacluster uid/gid.

The charms don't enable the acl and the package creates the hacluster
user in the haclient group, so I suspect there's something additional
going on here. For completeness, I'll attach the syslog in here. The
pacemaker node did start after following JuanJo's workaround in comment
#15.

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.
