|vol_id [--export] [-t] [-l] [-u] [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. vol_id supports all common filesystem formats and detects various raid setups to prevent the recognition of raid members as a volume with a filesystem.
|print all values in key/value format to import them into the environment.|
|-t||print the filesystem type|
|-l||print the label of a volume|
|-u||print the uuid of a volume|
|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.
