you can use on-fail in the stop operation and for your other questions
you can use colocation + order or better if you use a group: for
example group mygroup resource1 resource2
When resource1 monitor fails the resource2 restarts

If you want to use lvm with your oracle instance for space management:

the first thing that you need to configure is the stonith, because you have
this constraint "constraint order promote DrbdResClone then start HALVM"
To recover and promote drbd to master when you crash a node, configurare
the drbd fencing handler.

Sorry, but from my point of view, the agent first check if the
resource is running, for example you can check that from
/usr/lib/ocf/resource.d/heartbeat/Filesystem
The logic is
Filesystem::start(parameter as parameter for the
agent)->Filesystem_start(function called from start in the case which
