In this example, the failed device caused both a linear and a striped logical volume in the
volume group to fail. The
lvs
command without the
-P
argument shows the following output.
[root@link-07 tmp]# lvs -a -o +devices
Volume group "vg" not found
Using the
-P
argument shows the logical volumes that have failed.
[root@link-07 tmp]# lvs -P -a -o +devices

The following examples show the output of the
pvs
and
