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
recover.
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.
