[Pacemaker] [Problem] The cluster fails in the stop of the node.

[renayama19661014 at ybb.ne.jp]

Hi All,

When we set a group resource within Master/Slave resource, we found the problem that a node could not stop.

This problem occurs in Pacemaker1.0.11.

We confirmed a problem in the following procedure.

Step1) Start all nodes.

Stack: Heartbeat
Current DC: test2 (b645c456-af78-429e-a40a-279ed063b97d) - partition WITHOUT quorum
Version: 1.0.12-unknown
2 Nodes configured, unknown expected votes
4 Resources configured.
============

Online: [ test1 test2 ]

 Master/Slave Set: msGroup01
     Masters: [ test1 ]
     Slaves: [ test2 ]
 Resource Group: testGroup
     prmDummy1  (ocf::pacemaker:Dummy): Started test1
     prmDummy2  (ocf::pacemaker:Dummy): Started test1
 Resource Group: grpStonith1
     prmStonithN1       (stonith:external/ssh): Started test2
 Resource Group: grpStonith2
     prmStonithN2       (stonith:external/ssh): Started test1

Migration summary:
* Node test2: 
* Node test1: 

Step2) Stop Slave node.

[root at test2 ~]# service heartbeat stop
Stopping High-Availability services: Done.

Step3) Stop Master node. However, a loop does the Master node and does not stop.
