|
|
<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. <command>vol_id</command> supports all common filesystem formats
|
|
and detects various raid setups to prevent the recognition of raid members
|
|
as a volume with a filesystem.</para>
