        Hi
        

        How  do I determine, which part of the  code is run on the
          client, and which part of the code is run on the server
          nodes by merely looking at the the glusterfs  source code ?
        I knew  there are client side  and server side translators
          which will run on respective platforms. I am looking at part
          of self heal daemon source  (ec/afr) which will run on the
          server nodes  and  the part which run on the clients.
      
    
    The self-heal daemon that runs on the server is also a client
    process in the sense that it has client side xlators like ec or afr
    and  protocol/client (see the shd volfile 'glustershd-server.vol')
    loaded and talks to the bricks like a normal client does.

    The difference is that only self-heal related 'logic' get executed
    on the shd while both self-heal and I/O related logic get executed
    from the mount. The self-heal logic resides mostly in
    afr-self-heal*.[ch] while I/O related logic is there in the other
    files.

    HTH,

    Ravi
