Thanks Andrew for pointing towards the OCF resource agent's list of
"must implement" actions. I noticed that our OCF script only implements
start, stop and monitor. It does not implement meta-data and
validate-all. Could this error be a result of these un-implemented
actions?
Thanks

Yes, we have cman (version: cman-3.0.12.1-49). We use manual fencing ( I know

Perhaps subject line "resource is too active problem in a 2-node cluster" was
misleading. Real problem is that resource is *NOT* too active, but pacemaker thinks it is.
It only thinks what the resource agent tells us.
Sounds like script.sh isn't OCF compliant.

Which leads to undesirable recovery procedure. See log lines below

Turning off quorum on a 2-node cluster is fine, in fact, it's required.
However, that makes stonith all the more important. Without stonith, in any
cluster but in particualr on two node clusters, things will not work right.
First and foremost; Configure stonith and test to make sure it works.
Pacemaker version: 1.1.10
Corosync version: 1-4.1-15
OS: CentOS 6.4
With CentOS/RHEL 6, you need cman as well. Please be sure to also configure fence_pcmk in
cluster.conf to "hook" it into pacemaker's real fencing.
What am I doing wrong?

That. :)
Once you have stonith working, see if the problem remains.
