          Hello
            I want to undrestand the operation of dht translator,
              then i decide to debug the code for this aim.
            But i can not do that:(
            I think i should run gdb in client side, but how? I can
              not mount the file system for client from gdb. And if I
              mount seperately, I can not run any glusterfs within gdb
          
        
    1) Install debuginfo if you are using rpm, if you are using source
    code then configure with --enable-debig.

    2) Do a fuse mount from client (mount -t glusterfs
    server_hostname:/volname /mount_point)

    3) find the pidof the mount process (you can grep for glusterfs or
    with you volname)

    4) Attach gdb to the client process using gdb -p <pidof
    glusterfs>

    5) put your break points in dht functions and then you are good to
    go :)

            Is there any way to not using gdb and debug with printf
              (Iknow it is very stupid but is easy) and see the serult
              in the terminal?
