Hello, everybody. I'm trying to configure Pacemaker for using DRBD + OCFS2 storage, but I'm stuck with DRBD and controld up and o2cb doggedly displaying "not installed" errors. To do this, I followed the DRBD guide ( http://www.drbd.org/users-guide-8.3/ch-ocfs2.html), with the difference that I was forced to disable DRBD fencing because it was interfering with Pacemaker fencing and stopping each nodes as often as it could.
Now, as I said, I'm stuck with these errors (Malastare and Vindemiatrix
being the 2 nodes of my cluster) :
Failed actions:
p_o2cb_start_0 (node=Vindemiatrix, call=11, rc=5, status=complete):
not installed
p_o2cb_monitor_0 (node=Malastare, call=4, rc=5, status=complete):
not installed
Looking into logs, I find these messages :
o2cb[19904]: 2012/06/20_09:04:35 ERROR: Wrong stack o2cb
o2cb[19904]: 2012/06/20_09:04:35 ERROR: Wrong stack o2cb
I tried to manually test ocf:pacemaker:o2cb, but I got this result :
root@Malastare:/home/david# export OCF_ROOT="/usr/lib/ocf"
root@Malastare:/home/david# /usr/lib/ocf/resource.d/pacemaker/o2cb monitor
o2cb[22387]: ERROR: Wrong stack o2cb
root@Malastare:/home/david# echo $?
5
I tried the solution described on this message (
http://oss.clusterlabs.org/pipermail/pacemaker/2009-December/004112.html),
but tunefs.ocfs2 failed :

DANGER: YOU MUST BE ABSOLUTELY SURE THAT NO OTHER NODE IS USING THIS
FILESYSTEM BEFORE MODIFYING ITS CLUSTER CONFIGURATION.
Update the on-disk cluster information? yes

I also tried to manually set the cluster stack using "echo pcmk >
/sys/fs/ocfs2/cluster_stack" on both nodes, then restarting Corosync and
Pacemaker, but error messages stayed. Same thing with resetting OCFS2
FSs while cluster is on-line. Now I'm stuck, desperately waiting for
help Seriously, if some do-gooder would like to help me, I would
greatly appreciate his or her help.
Thank you in advance for your answers.
Kind regards.
