fence_manual works by you power cycling the affected node first before
trying to run fence_ack_manual

fence_manual creates the file - you'll have to see the logs on the
system to see what node created it; some nodes will say:

  fencing of X deferred to node Y

Step 1: Power cycle node X
Step 2: Log in to node Y and run fence_ack_manual -n X
