−
  -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

−
  -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>
