lvdisplay

lvdisplay is a command-line utility in the Linux Logical Volume Manager (LVM2) suite used to display the properties and metadata of logical volumes. It provides information about a single logical volume or all volumes in the system, drawing from the LVM metadata stored in volume groups and physical volumes. The tool is part of the LVM2 user-space tools, typically installed with the lvm2 package, and is used for administration, auditing, and troubleshooting.

Output includes identifiers and attributes such as the LV path and name, the associated volume group, the LV UUID, size, allocation mode, and status (for example whether the LV is open). It may also report the number of active mirrors or segments, read/write permissions, and creation time and host. Details presented vary with the LV and the options used; more exhaustive information is shown by default, while machine-readable or concise formats can be requested with specific options.

Usage examples: To display a particular logical volume, run lvdisplay /dev/vgname/lvname. To show information for all logical volumes, run lvdisplay without arguments. Some versions support machine-readable output via concise, colon-separated formatting via the -c option and verbose output via -v. Consult the system's man page for your version to learn available switches.

Relation: lvdisplay is one of several LVM2 inspection tools, alongside vgdisplay and pvdisplay, and complements creation and management commands such as lvcreate and lvremove. It helps administrators verify configurations, monitor capacity, and diagnose issues with logical volumes.
