Hi All,

We tested the trouble of the clone resource in the next procedure.


Step1) We start a cluster in three nodes.

Inactive resources:


Migration summary:
* Node srv01:  pingd=1
* Node srv03:  pingd=1
* Node srv02:  pingd=1

Step2) In a srv01 node, We generate the trouble of the clone resource.

[root at srv01 ~]# rm -rf /var/run/Dummy-prmDummy1.state 

Step3) In a srv02 node, it takes the reboot of the pingd clone. Under influence of this, rebooting, main_rsc2 reboots.
 * The number of the clone becomes funny somehow or other, too.

Failed actions:

We think the reboot of pingd to be unnecessary in a srv02 node. 
Is there the method how this problem is settled?

Possibly the next bug may be related.

I registered the log with Bugzilla.(attached hb_report)
