[Pacemaker] why does ressource go down on both nodes

[Guido Schmidt]

Hi to all,
please can someone explain to me why resource OCFS2 in my configuration stopped 
on node#2 by pacemakers-gui will also after a while stop upon node#1.
For me for maintenance purpose it will be helpful to stop OCFS2, CLVG01 and 
CLVM on one node only.
So the whole applications (4 tomcats, apache, postfix, cyrus) will be serviced 
on the other node (where the VIP1 will point to) during maintenance.
 
It seems to me, that it has worked as I described above some time ago;-)  I 
really could not find the mistake in my configuration.
 
Following the crm-configuration I am using now (based on SLES-HA v11.1-64Bit):
