DRBD sounds good in that it works at the block level Give drbd a try then. Just make sure you do enough tests first. I had a test setup with no fencing (yes, I know it's bad, that's why it's only a test) with dbrd+ocfs2, and sometimes a node failure cause unpredicatable cluster-wide error (both nodes restarting, split brain, etc). In production environment timeout for fencing should be lower than other subsystems (e.g. drbd). -- Fajar -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
