[Pacemaker] Pacemaker 1.1: cloned stonith resources require --force to be added to levels

In the end, I suppose it's only a "purist mindset" :) because it is a PDU whose power outlets control both nodes, so
its resource "should be" active (and monitored) on both nodes "independently".
I understand that it would work anyway, leaving it not cloned and not location-constrained
just as regular, "dedicated" stonith devices would not need to be location-constrained, right?

You're right! (obviously ;> )
It's been automatically named pdu1-clone

I suppose that there's still too much crmsh in my memory :)

Anyway, removing the stonith level (to start from scratch) and using the correct clone name does not change the result:

[root at cluster1 etc]# pcs -f stonith_cfg stonith level add 2 cluster1.verolengo.privatelan pdu1-clone
Error: pdu1-clone is not a stonith id (use --force to override)
[root at cluster1 etc]# pcs -f stonith_cfg stonith level add 2 cluster1.verolengo.privatelan pdu1-clone --force
[root at cluster1 etc]# pcs -f stonith_cfg stonith level verify
Error: pdu1-clone is not a stonith id
[root at cluster1 etc]# echo $?
1

I suppose that I should devise a testing strategy (like pulling iLO cables and causing a stonith to happen) to verify it.
 
Many thanks again for your help.

Regards,
Giuseppe
