Watch the respective kernel logs when issueing "drbdadm connect" on both nodes. There will be an indication of split brain if that's indeed your problem. If they are both currently Primary, that definitely *is* your problem. Even if it has not been the root cause, it's now your state of affairs. In that case, you will need this: http://www.drbd.org/users-guide/s-resolve-split-brain.html Seeing as you may have two active OCFS instances, it may be difficult to choose a victim in your scenario. Maybe you can do a data merge of some kind before you kill one of your FSes? HTH, Felix
