Maybe someone can tell us if i'm wrong here. > I've just been playing with a 4TB drbd volume using a dual primary configuration, openais and clvmd on openSuSE 11.1. Things seem to be OK so far. It appears that openais may have some issues though :-(, due to it's youth, and the clvm stuff doesn't have a startup script, so will need to play around a bit. Of course you still can't use the two primaries without either a clustered file system or as I hope to do, failover for iscsi based Xen domUs on separate dom0 servers with multipath.
