Then this is why you're stuck. RGmanager, gfs2 and clvmd all use DLM and 
they will block when DLM blocks. When a fence is called, fenced informs 
dlm, and dlm remains blocked until fenced tells dlm that it's safe to 

If you are *certain* that the one nodes is powered off (or rebooted and 
cman/rgmanager was not started), you can run 'fence_ack_manual' to tell 
fenced that the node was fenced. Be very careful with this; improper use 
can corrupt your cluster.

Alternatively, restart all nodes.
