We can also do "gluster peer detach <hostname> force right?

Just to be sure I setup a test 3 node vm gluster cluster :) then shut down
one of the nodes and tried to remove it.


root at gh1:~# gluster peer status
Number of Peers: 2

Hostname: gh2.brian.softlog
Uuid: b59c32a5-eb10-4630-b147-890a98d0e51d
State: Peer in Cluster (Connected)

Hostname: gh3.brian.softlog
Uuid: 825afc5c-ead6-4c83-97a0-fbc9d8e19e62
State: Peer in Cluster (Disconnected


root at gh1:~# gluster peer detach gh3 force
peer detach: failed: gh3 is not part of cluster

This looks like a bug in the error code as the error message is wrong. I'll
take a look at it and get back.
