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. -C, --cancel-fsck Cancel all scheduled fsck. -l, --balance Balance available space on storage pool devicesdrives. -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-attic trash Empty the attictrash. -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. -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-graveyardmetadata-store Speed up fsck by skipping the scan of the graveyardmetadata store directories. Scanning the graveyards 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, or 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.
