[Linux-cluster] Problem in fencing, gfs2 freezes



Hi, 

I have setup a Primary/Primary cluster with GFS2.

All works good if I shut down any node regularly, but when I unplug power of any node, GFS freezes and I can not access the device. 

Tried to use http://people.redhat.com/lhh/obliterate 

this is what I see in logs
