Displaying Physical Volumes

There are three commands you can use to display properties of LVM physical volumes: pvs, pvdisplay, and pvscan.

The pvs command provides physical volume information in a configurable form, displaying one line per physical volume.

The pvs command provides a great deal of format control, and is useful for scripting.

For information on using the pvs command to customize your output,

The pvdisplay command provides a verbose multi-line output for each physical volume. It displays physical properties (size, extents, volume group, etc.) in a fixed format. The following example shows the output of the pvdisplay command for a single physical volume.

# pvdisplay
— Physical volume —
PV Name /dev/sdc1

The pvscan command scans all supported LVM block devices in the system for physical volumes.

The following command shows all physical devices found:

# pvscan
PV /dev/sdb2 VG vg0 lvm2 [964.00 MB / 0 free]
PV /dev/sdc1 VG vg0 lvm2 [964.00 MB / 428.00 MB free]
PV /dev/sdc2 lvm2 [964.84 MB]
Total: 3 [2.83 GB] / in use: 2 [1.88 GB] / in no VG: 1 [964.84 MB]
