We're looking at using xen on SLES11SP1 servers in production at remote sites. We've been testing ocfs2 over dual primary drbd as one of the storage choices. It runs great, and is certainly more cost affective than putting SANs at our sites. Our big concern is split brain and how to handle that when it happens. If you have a large, shared storage over drbd with VMs running on either host, how do you handle a split brain situation from a recovery standpoint? One idea we had is to run multiple ocfs2/drbd's, one for each VM, and we can pick and choose which way to recover in a split brain. That seems like it makes it a lot more complex and not sure how successful it would even be. What has been your experience? Any suggestions are appreciated. Thanks, James
