That's a red herring. Why the Filesystem RA is still trying to modprobe scsi_hostadapter, and is even logging any failure to do so with a FATAL priority, don't ask. :) However, with all those target-role="Stopped" attributes in there nothing of interest is really expected to start. > in the /var/log/syslog > > I've been googling around for a solution but all of them seem to fail for me. > > any help is much appreciated That tutorial is wrong in several places. Specifically, "One word about OCFS2. In a perfect world, we should manage OCFS2 with pacemaker. In this particular case, this won't be the case (I had issues with lock managment which is mandatory for pacemaker)." ... is just nonsense. You can (and should) put the DLM and O2CB under Pacemaker management. See the ocf:pacemaker:controld and ocf:pacemaker:o2cb resource agents for details. Also, you'll probably need to update your OCFS2 with "tunefs.ocfs2 --update-cluster-stack" before you can mount it.
