Hi Tim, I spoke of ocfs2.pcmk , and I configured all the things as documented so that we got a unique cluster "pcmk" for both stacks : ocfs2 and pacemaker, and did many tests and "tuning" to make it work, but ... it was defintely not working.
I completely do agree that making a cluster ocfs2 "besides" the cluster pacemaker will definetely not work , but the configuration with dlm and ocfs2 pcmk stack are specific to work under pacemaker (so there is no ocfs2.conf, the name of the ocfs2 cluster is "pcmk") , but it does not work at all on RHEL6, it perhaps was working on previous RH releases, but Oracle told me that (in fall 2010) they had not "updated" even "tested" the ocfs2.pcmk stack to work with Pacemaker on RHEL6 ... but perhaps things have been done now (I doubt) Regards Alain De : Tim Serong <tser...@suse.com> A : linux-ha@lists.linux-ha.org Date : 26/10/2011 08:00 Objet : Re: [Linux-HA] PCMK + OCFS2 Envoyé par : linux-ha-boun...@lists.linux-ha.org On 26/10/11 16:42, alain.mou...@bull.net wrote: > Hi Nick, > > I spent e few weeks to try to make this stack ocfs2.pcmk working with > pacemaker/corosync stack > last fall 2010, and this stack was definitely not working on RH.

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.
