-v     print version information and exit

       -h     print usage information and exit

       -cCFGFILE
              specify   alternative  path  of  configuration  file  (default  is  mfschunkserver.cfg  in  system
              configuration directory)

       -n     do not attempt to increase limit of core dump size

       -tLOCKTIMEOUT
              how long to wait for lockfile (in seconds; default is 60 seconds)

       ACTION tells chunkserver to perform one of the following actions:

              start    Start chunkserver process if the process is not already running, otherwise display  error
                       message.

              stop     Stop chunkserver process if the process is running, otherwise display error message.

              restart  (default  action) If the chunkserver process is running, restart it, if it's not running,
                       start it.

              reload   Send a signal to chunkserver process to reload config files.

              info     Send a singal to chunkserver process to dump debug information file in working directory.

              test     Displays "mfschunkserver pid: PID" if the  chunkserver  is  running  (and  return  0)  or
                       "mfschunkserver is not running" otherwise (and return 1).
