[Pacemaker] Seeking for advice after cluster freeze

[Patrick Zwahlen]

Hi Dejan, and thanks for the super quick response.

I didn't want to do too many changes before having some people have a
look at
it. I agree there are some new pacemaker/cluster-glue revisions, though.

I think this comes from the RPM dependencies. If I try to remove
heartbeat
using 'yum', then it also wants to remove pacemaker. I am making sure
that
heartbeat doesn't start, though. Only corosync is configured to start at
system boot.

> Anything in logs? Or is that the log attached?

The attached logs (messages.2) show what happened just before and right
after
the freeze. The last log entry is at 17:26:59. The freeze lasts until
17:41:46. During that time, we should at a minimum have logs for drbd
monitoring (crm_attribute...).

This happens after the freeze and manual reboot. I am not sure why I get
this
error, but for sure after the other node came back up, everything worked
fine
again.

Thanks again, - Patrick -
