vol_id − probe filesystem type and read label and uuid
|
vol_id [−−export] [−−type] [−−label] [−−label−raw] [−−uuid] [−−skip−raid] [−−probe−all] [−−offset=bytes] [−−debug] [−−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
Print all values in key/value format to import them into the environment.
−−type
Print the filesystem type.
−−label
Print the safe version of volume label suitable for use as filename.
−−label−raw
Print the raw volume label.
−−uuid
Print the uuid of a volume.
−−skip−raid
Skip detection of raid metadata.
−−probe−all
Probe for all types and print all matches.
−−offset=bytes
Start probing at the given offset, instead of the beginning of the volume. The offset value is specified in bytes.
−−debug
Print debug messages to stderr.
−−help
Print usage.
UDEV_LOG
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.
