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

[Felipe Reyes]

I'm seeing this problem in another environment, similar deployment (3
lxc containers)

These are the only processes running in one of the nodes:

root       782  0.0  0.0  81464  1828 ?        Ss   Feb12  25:13 /usr/lib/pacemaker/lrmd
haclust+   784  0.0  0.0  73920   776 ?        Ss   Feb12   8:25 /usr/lib/pacemaker/pengine
root       780  0.8  0.0 130256  4152 ?        Ssl  16:50   0:00 /usr/sbin/corosync


A possible explanation could be: http://thread.gmane.org/gmane.linux.highavailability.corosync/592/focus=639

I only have logs for one of the nodes, I'm trying to get logs of the
other 2 nodes to get a better understanding of what was happening with
the communication.
