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.
