[Pacemaker] Can't failover Master/Slave with group(primitive x3) setting

Hi,

sorry for the confusion.

Pacemaker 1.0.10 OK(group resource can failover)
Pacemaker 1.0.11 NG(gruop resource just stop, can not failover)
Pacemaker 1.1 <- the latest hg (gruop resource just stop, can not failover)

By the way, your simulation showed dummy01 restart on bl460g1n13 again,
but dummy01 failed on bl460g1n13, so dummy01 should move to bl460g1n14.

Current cluster status:
Online: [ bl460g1n13 bl460g1n14 ]

  Resource Group: grpDRBD
     dummy01    (ocf::pacemaker:Dummy): Started bl460g1n13 FAILED
     dummy02    (ocf::pacemaker:Dummy): Started bl460g1n13
     dummy03    (ocf::pacemaker:Dummy): Started bl460g1n13
  Master/Slave Set: msDRBD [prmDRBD]
     Masters: [ bl460g1n13 ]
     Slaves: [ bl460g1n14 ]

 Transition Summary:

  * Executing action 12: dummy02_stop_0 on bl460g1n13
  * Executing action 2: dummy01_stop_0 on bl460g1n13

  * Executing action 13: dummy02_start_0 on bl460g1n13
  * Executing action 3: dummy02_monitor_10000 on bl460g1n13
  * Executing action 15: dummy03_start_0 on bl460g1n13
  * Executing action 4: dummy03_monitor_10000 on bl460g1n13


Thanks,
