<pre>Usage: greyhole [ACTION] [OPTIONS]
 
 
Where ACTION is one of:
 
  -?, --help            Display this help and exit.
 
  -D, --daemon          Start the daemon.
 
  -P, --pause          Pause the daemon.
 
  -R, --resume          Resume a paused daemon.
 
  -f, --fsck            Schedule a fsck.
 
  -C, --cancel-fsck    Cancel any ongoing or scheduled fsck operations.
 
  -l, --balance        Balance available space on storage pool drives.
 
  -B, --cancel-balance  Cancel any ongoing or scheduled balance operations.
 
  -s, --stats          Display storage pool statistics.
 
  -i, --iostat          I/O statistices for your storage pool drives.
 
  -L, --logs            Display new greyhole.log entries as they are logged.
 
  -S, --status          Display what the Greyhole daemon is currently doing.
 
  -q, --view-queue      Display the current work queue.
 
  -a, --empty-trash    Empty the trash.
 
  -b, --debug=filename  Debug past file operations.
 
  -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.
 
  -r, --replace[=path]  Tell Greyhole that you replaced the drive at <path>.
 
  -X, --fix-symlinks    Try to find a good file copy to point to for all broken
 
                        symlinks found on your shares.
 
  -p, --delete-metadata<=path>
 
                        Delete all metadata files for <path>, which should be a
 
                        share name, followed by the path to a file that is gone
 
                        from your storage pool.
 
  -U, --remove-share<=share_name>
 
                        Move the files currently inside the specified share from the
 
                        storage pool into the shared folder (landing zone),
 
                        effectively removing the share from Greyhole's storage pool.
 
 
For --stats and --view-queue, the available OPTIONS are:
 
  -j, --json            Output the result as JSON, instead of human-readable text.
 
 
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-metadata-store
 
                        Speed up fsck by skipping the scan of the metadata store
 
                        directories. Scanning the metadata stores 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 or smb.conf paths 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, a
 
                        sub-directory of a Samba share, or any directory on a
 
                        storage pool drive.
 
  -o, --find-orphaned-files
 
                        Scan for files with no metadata in the storage pool drives.
 
                        This will allow you to include existing files on a drive
 
                        in your storage pool without having to copy them manually.
 
  -k, --checksums      Read ALL files in your storage pool, and check that
 
                        file copies are identical. This will identify any problem
 
                        you might have with your file-systems.
 
                        NOTE: this can take a LONG time to complete, since it will read
 
                        everything from all your drives!
 
  -m, --delete-orphaned-metadata
 
                        When fsck find metadata files with no file copies, delete those
 
                        metadata files. If the file copies re-appear later, you'll need
 
                        to run fsck with --find-orphaned-files to have them reappear in
 
                        your shares.</pre>
