Hello,
I have configured a drbd0 resource (nfsdata) in pacemaker, acting as
active/passive, using the linbit resource agent with master/slave config.
It works ok in different operations I tried with pacemaker.
Then on both two nodes I'm going to test ocfs2 for another drbd1 resource I
have created (ocfs2data).
Env for drbd seems ok on both nodes, with ocfs2 fs mounted on both, but the
drbd0 pacemaker resource failed

drbd1 is not mentioned (yet) in my pacemajer config, but I notice I got this
error in messages, that seems to say that pacemaker tries to take care of
drbd1 too...

As I didn't see anything about caveats with multiple resources both managed
and not managed by pacemaker @ linbit site, I presumed it is possible.
Is this correct?
My current config is this (btw: there are nfs words in resources, but not a
nfs server inside at the moment...):
