Is there a special reason you're using both gnbd and manual fencing?  I've
never seen that done before and can't think of a reason you'd want to.

configured should still work.

Follow what the message says and run "fence_ack_manual -n bof226" on the
remaining node after verifying the failed node has been reset or otherwise
fenced.
