lvdisplay – Display Logical Volume Properties

The lvdisplay command in Linux is used to display the properties of a logical volume. Logical volumes are a way to manage disk space in Linux, and they are created using the lvcreate command. lvdisplay displays information about the logical volumes that are currently available on the system.

Overview

The lvdisplay command displays information about logical volumes, including their size, name, and status. Here is the basic syntax for the command:

lvdisplay [options] [LogicalVolumePath...]

Here, options are any additional options you want to pass to the command, and LogicalVolumePath is the path to the logical volume you want to display information about. If you do not specify a path, lvdisplay will display information about all logical volumes on the system.

Examples

Display information about all logical volumes on the system:

lvdisplay

Display information about a specific logical volume:

lvdisplay /dev/myvg/mylv

Options

The following table lists the available options for the lvdisplay command:

Option Description
-a, --all Display information about all logical volumes, including hidden ones.
-c, --colon Use colon-separated output instead of the default human-readable output.
-m, --maps Display information about the logical volume’s mapping(s).
-o, --options Specify the columns to display.
-v, --verbose Display verbose output.

Troubleshooting Tips

If you are having trouble using lvdisplay, here are some common issues and their solutions:

  • “Command not found”: If you receive this error message, it means that the lvdisplay command is not installed on your system. You can install it using your package manager. For example, on a Debian-based system, you can run sudo apt-get install lvm2.
  • “No logical volumes found”: If you receive this error message, it means that there are no logical volumes on your system. You can create one using the lvcreate command.

Notes

  • lvdisplay is a read-only command, so it cannot be used to modify logical volumes.
  • If you want to display information about physical volumes instead of logical volumes, you can use the pvdisplay command.
  • lvdisplay is part of the LVM (Logical Volume Manager) package, which is not installed by default on some Linux distributions.
