I also received this warning some minutes ago:

Message from syslogd at x at Feb  2 16:54:35 ...
 corosync[6368]:   [TOTEM ] LOGSYS EMERGENCY: TOTEM Unable to write to
/var/log/cluster/corosync.log.

Message from syslogd at x at Feb  2 16:54:36 ...
 corosync[6368]:   [QUORUM] LOGSYS EMERGENCY: QUORUM Unable to write
to /var/log/cluster/corosync.log.

Do I have to fiddle with the mcast parameters?
