Re-adding an existing brick to a volume
.gluster and attr already in that folder so it would not connect it as a brick I don't think there is option to "reconnect brick back" what I did many times - delete .gluster and reset attr on the folder, connect the brick and then update those attr. with stat commands example here http://lists.gluster.org/pipermail/gluster-users/2018-January/033352.html Vlad On Sun, Feb 25, 2018
