[Gluster-users] glusterfsd won't restart on one brick

I think I've found the problem. The problem is not with the brick port, but
instead with the unix domain socket used for communication between glusterd
and glusterfsd.

socket.glusterfsd is the transport which is bound to the socket file
specified, which is  /var/run/5a538b707ce5dbf525ba6d01835863bb.socket in
this case as specified by the -S option.
The 'binding to' log should have printed the address:port identifier if
this was a log for a port.

So this is most likely due the zombie process 23744 still listening on the
unix domain socket. Only one bind can be performed on a unix domain socket.
If another bind is tried we get an EADDRINUSE error.

Can you kill 23744, remove /var/run/5a538b707ce5dbf525ba6d01835863bb.socket
and restart the brick using 'gluster volume start'. This should allow it to
