This is where you get into the problem. I am really not sure what
happens when you reboot a board. In our earlier conversation w.r.t to a
similar problem you did mention that board reboot doesn't wipe of
/var/lib/glusterd, please double confirm!

Also please send cmd_history.log along with glusterd log from both the
nodes. Also post reboot are you also trying to detach/probe A? If so
before detaching was A & B were in cluster connected state?
