[Ocfs2-users] ocfs2 fencing and half qurom issue

[Joseph Blackburn]

One of the nodes in a two node system keeps crashing every couple of
weeks. I'm getting this error message in /var/log/messages.

I've already changed my threshold settings to the following:

>cib-sim-wec-04:/proc/fs/ocfs2_nodemanager # more hb_dead_threshold
>46

Here's a little background. Two node setup DL580s, with x-over cables
for heartbeats.
SLES9-SP3. OCFS2 version 1.1.7.

Any help would be greatly appreciated.
Thanks
