<refsect1><title>DESCRIPTION</title>
|
|
<para><command>vol_id</command> 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.</para>
