Hi, I have tried to get this setup up and running a few weeks ago, but at the time I had issues with iSCSI failover (running on CentOS 5.4 VMs). Would you share your pacemaker config ? I have now also moved to NFS. From a perf point of view, a single VM on an NFS datastore looks slower than on an iSCSI LUN, but I think NFS scales much better. Even VMware recommends to go no further than 16 VM on a LUN, compared to 250 on an NFS store. The issue with NFS is that you can't go dual-primaries (unless you are NetApp, probably). I haven't found a way to have 2 NFS servers running in parallel, and exporting the same filesystem (due to NFS storing information locally in /var/lib/nfs). As far as I can tell, even a cluster FS (OCFS2, GFS) wouldn't help. However, the problem can be solved by running two single-primary clusters. This requires 4 VMs, and a slight admin overhead, but seems to work well. Sorry, for not answering the question, though. Just my 2 cents... Regards
