lvname

lvname is the name given to a logical volume within a volume group in the Linux Logical Volume Manager (LVM). In LVM, storage is organized into volume groups that contain one or more logical volumes. lvname serves as the unique identifier for a specific LV within its volume group and is used when addressing the LV in commands and device paths.

Naming and addressing: The LV name is combined with the volume group name to form the device path, commonly /dev/vgname/lvname or, in device-mapper mappings, as /dev/mapper/vgname-lvname. lvnames must be unique within a volume group. The allowed character set and length are constrained by the LVM version and kernel, and most administrators use simple ASCII names composed of letters, numbers, underscores, or dashes to ensure script compatibility.

Operations: LV management involves commands such as lvcreate -n lvname -L size vgname to create, lvdisplay or lvs to show properties, lvrename vgname oldname newname to rename, and lvremove /dev/vgname/lvname to delete. Logical volumes can be extended, reduced, or snapshotted, with lvname remaining the identifying label for these operations.

Usage considerations: When planning LV names, consider consistency across the environment, readability, and automation. In scripted or automated environments, lvname is often parameterized; ensuring uniqueness and avoiding reserved words helps prevent conflicts and errors.
