NAME
vol_id - probe filesystem type and read label and uuid
SYNOPSIS
vol_id [--export] [--type] [--label] [--label-raw] [--uuid] [--skip-raid] [--probe-all] [--help] [device]
DESCRIPTION
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
Print all values in key/value format to import them into the environment.
--type

--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.
ENVIRONMENT
UDEV_LOG
Set the syslog priority.
EXIT STATUS
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.
