OK, I found what's wrong. From the brick's log:

So several leftover processes. What will happen if I do a

/etc/init.d/glusterd stop
/etc/init.d/glusterfsd stop

kill all remaining gluster processes and restart gluster on this node?

Will the volume stay online? What about split-brain? I suppose it would be
best to disconnect all clients first...?
