Hi,
I think the problem would be around the fact that you try to mount the
underlying device of your drbd array. You should be mounting
/dev/drbd1 not your LVM volume. (The volume most be available
thought).
Btw, syncer at 10M is kinda low. You should consider using 1Gbps
network card and an higher value for your cross-link.
