Hi,

I could be wrong here but I'm pretty sure that you have to start the drbd "service" on the nodes before heartbeat and that the heartbeat resource agent isn't meant to start and stop the drbd service, it's meant to control the state of individual drbd devices you've configured with drbd.conf.

I don't use the OCF RA for my drbd devices, I use the LSB RA and that's how it works for me. When my nodes boot, they start the drbd service automatically. When I manually start heartbeat on each node, the drbd resource agents make sure that the drbd devices are set to primary on the nodes that I want based on rsc_location constraints and pingd status.
