The command "sudo vgdisplay" is used in Linux systems to display information about all the volume groups (VGs) configured on the system. Here's a breakdown of the command:
-
"sudo": This is a command used to execute another command with elevated privileges. It stands for "Super User Do" and allows the user to run commands as the superuser or root.
-
"vgdisplay": This is the main command that retrieves information about volume groups. It is part of the Logical Volume Manager (LVM), which is a system for managing logical volumes on Linux.
When you run "sudo vgdisplay", it will display detailed information about volume groups configured on the system, including their name, UUID, VG size, the number of physical volumes (PVs) used, the number of logical volumes (LVs) in the group, and other properties such as permissions, allocation policies, and metadata backups.
Overall, "sudo vgdisplay" is a useful command for administrators or users who need to know the configuration and status of volume groups on a Linux system.
