4.2.2. 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, see
"Customized Reporting for
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
VG Name

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