[Pacemaker] group depending on clones restarting unnescessary

I set up HA NFS Server according to the HOWTO from linbit. Basically it is a 
clone of the NFS server and a clone of the root filesystem. A group of the 
Filesystem, the exportfs and the ip address depends on a DRBD and the root-
exportfs clone.

See below for the configuration.

Lets say, the group run in node A and I put node B into standby everything 
looks good. But when I set node B online again the NFS-group  restarts 
although it runs on node A where which is not touched by the restart of the 
second half of the clone.

Any explanation? I tried to set the clone interleave and non-globally-uniq, 
but nothing helps.

Thanks for any hints.
