You can't (or at least, seriously shouldn't - that way lies madness) have both Pacemaker and O2CB simultaneously managing the cluster. I can't speak for OCFS2 support on Debian or RHEL, but I can suggest reading: * The previous version of Clusters from Scratch (labelled "OpenAIS") at http://www.clusterlabs.org/wiki/Documentation (this is old, but refers to OCFS2). * The relevant chapter of the SLE HA documentation: http://www.novell.com/documentation/sle_ha/book_sleha/?page=/documentation/sle_ha/book_sleha/data/part_storage.html * Lars' blog post about using clone-of-group configuration in Pacemaker: http://www.advogato.org/person/lmb/diary/104.html HTH, Tim > > Let us know. > Thanks a lot > Alain Moullé > > > > De : Nick Khamis<sym...@gmail.com> > A : General Linux-HA mailing list<linux-ha@lists.linux-ha.org> > Date : 25/10/2011 20:14 > Objet : [Linux-HA] PCMK + OCFS2 > Envoyé par : linux-ha-boun...@lists.linux-ha.org > > > > Hello Everyone, > > Moving forward, I noticed that there was not much documentation > regarding getting the pcmk stack working > with ocfs2.
