 "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.

--label

--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


Print usage.



 "ENVIRONMENT"

UDEV_LOG

 "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.
