The ocfs2 version should be the same on all the nodes. Mixing nodes
with 1.1.8 and 1.2.1 will cause problems. We had fixed a lot of issues
in 1.2.1. I'll write more when I reread your prev email.

Additionally I noticed last night, when I was shortly disabling the complete
network of all of those machines that after restoring the network, the last two
machines (older ocfs2 version) were confused and didn't rejoin the cluster
before the system reboot.
So, I guess first step is to update last two on ocfs2 version 1.2.1 ?
Although they were not directly involved in corruption, maybe indirect ?
Thanks,
Vladan

What version of ocfs2 is on the nodes? Do modinfo ocfs2 on all nodes.
The version of OCFS2 shipped with SLES9 SP3 varies with kernel.
Are you using the modules shipped by suse or building them yourself?
