This means that the glusterfsd process for this brick is offline. Can 
you please check the log files of this brick to determine why it failed? 
It could be related to missing extended attribute 
"trusted.glusterfs.volume-id" on the brick directory.  If that is the 
case you can copy the same extended attribute from the other brick 
directory.

Once both bricks are online, self-heal would kick in to rebuild data on 
the replaced brick.
