The following commandline switches are supported to specify what vol_id should print: - - --export prints all values - -h prints help text - -l prints the label of the volume - -u prints the uuid of the volume + --export export key/value pairs + --type filesystem type + --label filesystem label + --label-raw raw label + --uuid filesystem uuid + --skip-raid don't probe for raid + --probe-all find possibly conflicting signatures + --help vol_id will only return successful if the string asked for, is not empty.
