Hello.
Yes, we get the same kind of thing. SLES11 HAE 64-bit.

We seem to have randomly picked up a standby="off" node attribute, I
can't see it's causing any problems but I'm too afraid to make any
changes at the moment in case we have a(nother) shootout.

Subject: [Pacemaker] OCFS2 fencing regulated by Pacemaker?
Hi,
I'm trying to set up OCFS2 in a pacemaker environment (SLES11 with HAE),
in a 3 node cluster. Now I succesfully configured two volumes, the dlm
and the o2cb resource. But: if I shut down one of the nodes, at least
one other node (and sometimes even two!) is fencing itself.
I've been looking for the a way to control this behavior, but can't find
anything.
Does anyone have a clue?
Thanks,
Sander
