For a different reason, I have been using a subdirectory of the mountpoint
for the brick - e.g. if the filesystem is /mnt/xyz then I have done
mkdir /mnt/xyz/brick1 and set the brick as server1:/mnt/xyz/brick1

However I think this also fixes your problem, because if you try to mount
when the brick1 directory is not present, the glusterfsd process doesn't
start.  The client doesn't get a good error message, but buried in the
server logs you can see what happened.
