You can use the -P argument of the lvs or vgs command to display information about a failed

volume that would otherwise not appear in the output. For information on the output this argument

yields, see Section 6.2, “Displaying Information on Failed Devices”.

For a full listing of display arguments, see the pvs(8), vgs(8) and lvs(8) man pages.

Volume group fields can be mixed with either physical volume (and physical volume segment) fields or

with logical volume (and logical volume segment) fields, but physical volume and logical volume fields

cannot be mixed. For example, the following command will display one line of output for each physical

volume.

# vgs -o +pv_name

VG #PV #LV #SN Attr VSize VFree PV

new_vg 3 1 0 wz--n- 51.42G 51.37G /dev/sdc1

new_vg 3 1 0 wz--n- 51.42G 51.37G /dev/sdd1

4.8.2. Object Selection

This section provides a series of tables that list the information you can display about the LVM objects

with the pvs, vgs, and lvs commands.

For convenience, a field name prefix can be dropped if it matches the default for the command.

For example, with the pvs command, name means pv_name, but with the vgs command, name is

interpreted as vg_name.

Executing the following command is the equivalent of executing pvs -o pv_free.

# pvs -o +free

PFree

The pvs Command

Table 4.1, “pvs Display Fields” lists the display arguments of the pvs command, along with the field

name as it appears in the header display and a description of the field.
