pvchange [options] PhysicalVolume...

pvchange changes the attributes of a physical volume in LVM. It can control allocation, metadata handling, tagging, and UUID generation for physical volumes.

-x, --allocatable {y|n}

Allow or disallow allocation of physical extents on this volume

Ignore or use metadata areas on this physical volume

Add a tag to the physical volume

Remove a tag from the physical volume

Generate a new UUID for the physical volume

Change all visible physical volumes

Force operation

Verbose mode

Use --uuid with caution as it can cause problems if the volume group is active or if backups refer to the old UUID. Disabling allocation on a PV prevents new extents from being placed on it.

pvchange is part of LVM2 (Logical Volume Manager), providing flexible disk management and storage virtualization for Linux systems.
