[Pacemaker] Cluster Volume Group is stuck

This is an Update to my last Mail:

SBD is running on one Node normally:

Online: [ multix246 multix244 multix245 ]

  Clone Set: dlm_clone [dlm]
      Started: [ multix244 multix245 multix246 ]
  Clone Set: clvm_clone [clvm]
      Started: [ multix244 multix245 multix246 ]
  Clone Set: vgsmet_clone [vgsmet]
      Started: [ multix244 multix245 multix246 ]
  smetserv       (ocf::heartbeat:Xen):   Started multix244
  SBD_Stonith    (stonith:external/sbd): Started multix245  <----------

but after powering off Node multix246, it is running on two nodes:


Node multix246: UNCLEAN (offline)
Online: [ multix244 multix245 ]

  Clone Set: dlm_clone [dlm]
      Started: [ multix244 multix245 ]
      Stopped: [ dlm:2 ]
  Clone Set: clvm_clone [clvm]
      Started: [ multix244 multix245 ]
      Stopped: [ clvm:2 ]
  Clone Set: vgsmet_clone [vgsmet]
      Started: [ multix244 multix245 ]
      Stopped: [ vgsmet:2 ]
  smetserv       (ocf::heartbeat:Xen):   Started multix244
  SBD_Stonith    (stonith:external/sbd) Started [ multix245  multix246 ] <-----

If I power on the lost node again, everything recovers: only one SBD
is running, and:

  sbd -d /dev/disk/by-id/scsi-3600a0b8000420d5a00001cf14dc3a9a2-part1 list
0       multix244       clear
1       multix245       clear
2       multix246       clear
