lstor

lstor is a command-line utility designed for interacting with LVM, the Logical Volume Manager in Linux. It provides a convenient way to list and display information about LVM logical volumes, volume groups, and physical volumes. The primary function of lstor is to present a structured overview of the LVM setup on a system.

When executed, lstor typically displays details such as the names of logical volumes, their corresponding volume groups, sizes, and their state (e.g., active or inactive). It can also provide information about volume groups, including their total size, free space, and the physical volumes that comprise them. For physical volumes, lstor shows their device names, sizes, and whether they are currently part of any volume groups.

The utility is useful for system administrators and users who need to quickly understand the LVM configuration without delving into more complex LVM commands. It offers a straightforward way to check the status of LVM storage and identify available space or logical volumes. While lstor itself does not modify LVM structures, it serves as a fundamental tool for monitoring and planning LVM operations.
