            Bug ID: 1343926
           Summary: port-map: let brick choose its own port
           Product: GlusterFS
           Version: mainline
         Component: rpc
          Assignee: bugs at gluster.org

Description of problem:
In the current implementation, glusterd will choose a free port and pass
that to brick which need to bind on it, if you observe carefully there is
window
open for race here. In case, if the passed port was consumed by some other
processes then brick will fail to bind. In the recent past we have addressed
this issue by returning EADDRINUSE from brick to glusterd after which glusterd
will allocate a port from refreshed free ports list, but I feel that's kind of
too much of automation and also a hacky way.
