[Pacemaker] Loosing corosync communication clusterwide

[Daniel Dehennin]

Hello,

I just have an issue on my pacemaker setup, my dlm/clvm/gfs2 was
blocked.

The “dlm_tool ls” command told me “wait ringid”.

The corosync-* commands hangs (like corosync-quorumtool).

The pacemaker “crm_mon” display nothing wrong.

I'm using Ubuntu Trusty Tahr:

- corosync 2.3.3-1ubuntu1
- pacemaker 1.1.10+git20130802-1ubuntu2.1

My cluster was manually rebooted.

Any idea how to debug such situation?

Regards.
