Hi,
I don't know if it helps, but groupd is using all available CPU, but
only in 2 of the nodes.
That sounds like https://bugzilla.redhat.com/show_bug.cgi?id=444529
which is fixed in 5.3. I suspect that's the cause of you're problems.

We seem to be having the same problem on a 5 node virtual cluster
where 3 of the nodes share a GFS mount.
A backup script runs on one node which does some heavy reads + writes
to this mount at which point all three nodes jump to 100% cpu (90%
iowait on the machine that is doing the backup, 100% system on the
other two) and all LVM VGs, LVs and GFS mounts lock up.
Is there anything that could be tuned here to avoid this issue until a
bug fix is released?
Regards,
Tom
