lvs is a command in Linux used to display information about Logical Volumes (LVs) in a Linux Logical Volume Manager (LVM) system. The lvs command outputs a table of information about each LV in a system, including LV name, volume group (VG) name, size, status, and more. The lvs command can also be used with various options to display specific information about LVs, such as device paths, UUIDs, or to format the output in a custom way. The lvs command is a useful tool for viewing information about LVs and verifying the status of LVM storage configurations.
