Hi-
I'm trying to debug a problem that has surfaced recently in our clvmd
2.02.56 + openais 1.1.1 + corosync 1.1.2 cluster. We use clvmd to manage
volumes on a shared iSCSI storage array. We have four nodes in our
cluster, and after running for a while we start getting errors when trying
to perform LVM operations such as:
r...@babylon-four:~# lvs
cluster request failed: Cannot allocate memory
Can't get lock for xenvg
Skipping volume group xenvg
cluster request failed: Cannot allocate memory
Can't get lock for babylon-four
and
r...@citadel-station:~# lvcreate -L 1G -n quentin-test-2 xenvg
Error locking on node 1280050a: Cannot allocate memory
Error locking on node 1380050a: Cannot allocate memory
Error locking on node 1180050a: Cannot allocate memory
Error locking on node 1080050a: Cannot allocate memory
Aborting. Failed to activate new LV to wipe the start of it.
We had been able to clear these errors up by restarting corosync and
clvmd, but now that we've added another two nodes to our cluster, we're
getting these errors very frequently. Is there a buffer somewhere that we
need to increase the size of? I've attached our current corosync.conf to
the end of this message.
(Needless to say, the servers all have plenty of RAM free...)
Thanks,
--Quentin
