Linux Cluster Heartbeat and /dev/drbd0
How to enable access to a /dev/drdb0
Assuming that your cluster is already configured
you can use the following commands to check the status
#service drbd status
#drbdadm state r0 ( being r0 the name of the disk resource )
and to make current node Primary for a given disk (r0)
#drbdadm primary r0
After this you gain access to the /dev/drbd0 access.
