Both OCFS2 and GFS are meant to be used on SANs with shared storage(same
LUNs being accessed by multiple servers), I just re-confirmed that DRBD
is not a shared storage mechanism but just a simple block mirroring
technology between a couple of nodes(as I originally thought).
I think you are mixing incompatible technologies. Even if you can
get it working, just seems like a really bad idea.
Perhaps what you could do is setup an iSCSI initiator on your DRBD
cluster, export a LUN to another cluster running OCFS2 or GFS(last I
checked GFS required at least 3 nodes less than that and the cluster
goes to read-only mode, I didn't see any minimum requirements for
OCFS2).
Though the whole concept of DRBD just screams to me crap performance
compared to a real shared storage system, wouldn't touch it with
a 50 foot pole myself.
