Hello everyone,
we are having some problems with pacemaker and/or related software. I 
hope you can help to shed some light on the issues we are facing.

Our Setup consists of 2 nodes and 5 services running on these nodes.

Here comes the first problem, i will show you the output of "crm_mon -1":

Last updated: Thu Feb 20 08:56:44 2014
Last change: Tue Feb 18 15:12:41 2014 via crm_attribute on drbd0
Stack: classic openais (with plugin)
Current DC: drbd1 - partition with quorum
Version: 1.1.10-14.el6_5.2-368c726
3 Nodes configured, 2 expected votes
5 Resources configured

Online: [ drbd1 ]
OFFLINE: [ drbd0 drbd0.sp.local ]

  Resource Group: rg_drbd
      drbd_iscsi_target  (ocf::heartbeat:iSCSITarget):   Started drbd1
      drbd_iscsi_lun1    (ocf::heartbeat:iSCSILogicalUnit): Started drbd1
      ClusterIP  (ocf::heartbeat:IPaddr2):       Started drbd1
  Master/Slave Set: drbd_master_slave [drbd_res]
      Masters: [ drbd1 ]
      Stopped: [ drbd0 drbd0.sp.local ]

Failed actions:
     drbd_iscsi_target_monitor_10000 on drbd1 'unknown error' (1): 
call=125, status=Timed Out, last-rc-change='Fri Feb  7 20:26:10 2014', 
queued=0ms, exec=0ms
     drbd_res_monitor_29000 on drbd1 'unknown error' (1): call=38, 
status=Timed Out, last-rc-change='Fri Feb  7 20:24:36 2014', queued=0ms, 

As you can see it says "3 Nodes configured", because it counts drbd0 as 
two nodes. So this would be my first question.

As for the failed actions: I get "unknown error" for both, is there some 
way to debug this further? Maybe it is related to the "double node", so 
i wont have to investigate further.

And the third problem would be: I can't get the "drbd0"-node online via 
crm-shell, however i can put it in standby mode, so it obviously reacts 
to commands.

Would be great if you could help me with that!
