You defintely must not use the deprecated ocf:heartbeat:drbd resource
agent but the one that comes with DRBD: ocf:linbit:drbd ... you should
see a big fat warning in your logs to not use it.
And this colocation is wrong:
...
<rsc_colocation id="drbd-nfs-ha" rsc="ms-drbd_r0"
rsc-role="Master" score="INFINITY" with-rsc="nfs_resources"/>
...
rsc and with-rcs need to be the other way round
<rsc_colocation id="drbd-nfs-ha" rsc="nfs_resources" score="INFINITY"
with-rsc="ms-drbd_r0" with-rsc-role="Master" />
... give this a try.
