vgname

vgname is a term used in computing, most commonly to denote the name assigned to a volume group in the Linux Logical Volume Manager (LVM). A volume group combines one or more physical volumes into a pool from which logical volumes are created.

In LVM, the vgname functions as the identifier of the volume group within the host system. It is stored in the VG metadata and is used by management tools to reference the group. Commands such as vgdisplay, vgscan, vgchange, and vgremove operate on a volume group identified by its vgname. The vgname should be unique on a given host to avoid ambiguity. Renaming a volume group changes the vgname; this can be done with a dedicated command (vgrename) but should be planned carefully because existing logical volumes, scripts, and mount configurations may depend on the old name.

Outside of LVM, vgname may appear as a placeholder in tutorials or configuration examples to illustrate naming conventions for a volume group. In those contexts, it represents a variable that users replace with an actual group name.
