In this case glusterd stops the brick processes but doesn't mark its status as stopped.
Ravi, correct me if I am wrong.

It waits for the other node's glusterd also to be up so that they are in sync. You can override this behavior by doing a `gluster volume start <volname> force` to bring up the gluster process only on this node and then mount the volume.
