4.4.7. Displaying Logical Volumes

download PDF
There are three commands you can use to display properties of LVM logical volumes: lvs, lvdisplay, and lvscan.
The lvs command provides logical volume information in a configurable form, displaying one line per logical volume. The lvs command provides a great deal of format control, and is useful for scripting. For information on using the lvs command to customize your output, see Section 4.9, “Customized Reporting for LVM”.
The lvdisplay command displays logical volume properties (such as size, layout, and mapping) in a fixed format.
The following command shows the attributes of lvol2 in vg00. If snapshot logical volumes have been created for this original logical volume, this command shows a list of all snapshot logical volumes and their status (active or inactive) as well.
lvdisplay -v /dev/vg00/lvol2
The lvscan command scans for all logical volumes in the system and lists them, as in the following example.
# lvscan
 ACTIVE                   '/dev/vg0/gfslv' [1.46 GB] inherit
