Yes it is.

> mount /dev/drbd0 on the Secondary as well?

No, the drbd device MUST (*) be always only mounted on the primary node. The 
idea is that heartbeat will manage which of both node is the current primary 
and so will adjust it properly.


PS: (*): Of course, there are always exceptions for everything, but until one 
understands the concept, one better shouldn't try to do unusual things ;-)
