NAME

6       vol_id - probe filesystem type and read label and uuid
7

SYNOPSIS

9       vol_id [--export] [--type] [--label] [--label-raw] [--uuid]
10              [--skip-raid] [--probe-all] [--help] [device]
11

DESCRIPTION

13       vol_id is usually called from a udev rule, to provide udev with the
14       filesystem type, the label and the uuid of a volume. It supports most
15       of the common filesystem formats and detects various raid setups to
16       prevent the recognition of raid members as a volume with a filesystem.
