lvdisplay

The lvdisplay command line tool is a part of the LVM (Logical Volume Manager) package used in Linux environments. It is used to fetch and display information about logical volumes. When executed, it presents a detailed summary of the logical volumes available on a system.

The output provided by lvdisplay includes information such as the logical volume name, the volume group it belongs to, the size of the logical volume, physical extent sizes, and the percentage of space used.

Furthermore, lvdisplay also provides information about the type of file system used on the logical volume and its mount point, along with other relevant details such as whether the logical volume is mirrored or striped.

It is a useful command line tool for administrators to get an overview of the logical volumes configured on a machine and helps in diagnosing issues, managing storage, and planning expansions or changes to the logical volume setup.

lvdisplay is generally used in conjunction with other LVM tools such as vgdisplay (Volume Group Display) and pvdisplay (Physical Volume Display) to obtain a comprehensive view of the storage setup on a Linux system using LVM.

In summary, lvdisplay provides a convenient way to examine and understand the characteristics and configuration of logical volumes, aiding in effective storage management within a Linux environment.
