= Greyhole =
 
Use just "greyhole" in a Terminal to get the list, since those could change in the future. Currently, they are:
 
 
 
  Usage: greyhole [ACTION] [OPTIONS]
 
 
 
  Where ACTION is one of:
 
 
 
    -?, --help            Display this help and exit.
 
    -D, --daemon          Start the daemon.
 
    -f, --fsck            Schedule a fsck.
 
    -l, --balance        Balance available space on storage pool devices.
 
    -s, --stats          Display storage pool statistics.
 
    -S, --status          Display what the Greyhole daemon is currently doing.
 
    -q, --view-queue      Display the current work queue.
 
    -a, --empty-attic    Empty the attic.
 
    -b, --debug=filename  Debug past file operations.
 
    -p, --prerotate      Pre-rotate task (for logrotate).
 
    -P, --postrotate      Post-rotate task (for logrotate).
 
    -t, --thaw[=path]    Thaw a frozen directory. Greyhole will start working on
 
                          files inside <path>. If you don't supply an option, the list
 
                          of frozen directories will be displayed.
 
    -w, --wait-for[=path] Tell Greyhole that the missing drive at <path> will return
 
                          soon, and that it shouldn't re-create additional file copies
 
                          to replace it. If you don't supply an option, the available
 
                          options (paths) will be displayed.
 
    -g, --gone[=path]    Tell Greyhole that the missing drive at <path> is gone for
 
                          good. Greyhole will start replacing the missing file copies
 
                          instantly. If you don't supply an option, the available
 
                          options (paths) will be displayed.
 
    -n, --going[=path]    Tell Greyhole that you want to remove a drive. Greyhole will
 
                          then make sure you don't loose any files, and that the
 
                          correct number of file copies are created to replace the
 
                          missing drive. If you don't supply an option, the available
 
                          options (paths) will be displayed.
 
 
 
  For --fsck, the available OPTIONS are:
 
    -e, --email-report    Send an email when fsck completes, to report on what was
 
                          checked, and any error that was found.
 
    -y, --dont-walk-graveyard
 
                          Speed up fsck by skipping the scan of the graveyard
 
                          directories. Scanning the graveyards is only required to
 
                          re-create symbolic links that might be missing from your
 
                          shared directories.
 
    -c, --if-conf-changed Only fsck if greyhole.conf changed since the last fsck.
 
                          Used in the daily cron to prevent unneccesary fsck runs.
 
    -d, --dir=path        Only scan a specific directory, and all sub-directories.
 
                          The specified directory should be a Samba share, or a
 
                          sub-directory of a Samba share.
