vol_id - probe filesystem type and read label and uuid
vol_id [−−export] [−−type] [−−label] [−−label−raw] [−−uuid] [−−skip−raid] [−−probe−all] [−−help] [device] |
vol_id is usually called from a udev rule, to provide udev with the filesystem type, the label and the uuid of a volume. It supports most of the common filesystem formats and detects various raid setups to prevent the recognition of raid members as a volume with a filesystem.
−−export

−−label
Print the safe version of volume label suitable for use as filename.
−−label−raw

−−uuid
Print the uuid of a volume.
−−skip−raid
Skip detection of raid metadata.
−−probe−all
Probe for all types and print all matches.
−−help

Set the syslog priority.
vol_id will only return successful if the value asked for is not empty. All trailing whitespace will be removed, spaces replaced by underscore and slashes ignored.
