Example from my haressources file:
test-neu1 10.192.64.63 \
MailTo::support at icomedias.com::test-neu-db
So mount/unmount is handled by using the "Filesystem" ressource script
provided with heartbeat.

If you're using internal metadata, drbd should realize that the disk is
new and resync by itself. If you want to explicitely resync a device you
can use "drbdadm invalidate <ressource>" on the side with bad data.

You'll definitely want to try failovers before putting a system in
production. you can monitor current status of drbd by checking the
information from cat /proc/drbd.
