pvchange

Modify LVM physical volume attributes

TLDR

Allow allocation on physical volume

$ sudo pvchange -x y /dev/sdXN

Disallow allocation on physical volume

$ sudo pvchange -x n /dev/sdXN

Ignore metadata areas

$ sudo pvchange --metadataignore y /dev/sdXN

Stop ignoring metadata areas

$ sudo pvchange --metadataignore n /dev/sdXN

Add tag to physical volume

$ sudo pvchange --addtag mytag /dev/sdXN

Generate new UUID

$ sudo pvchange --uuid /dev/sdXN

Change all visible physical volumes

$ sudo pvchange -a -x y

SYNOPSIS

pvchange [options] PhysicalVolume...

DESCRIPTION

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

PARAMETERS

-x, --allocatable {y|n}

Allow or disallow allocation of physical extents on this volume

--metadataignore {y|n}

Ignore or use metadata areas on this physical volume

--addtag TAG

Add a tag to the physical volume

--deltag TAG

Remove a tag from the physical volume

--uuid

Generate a new UUID for the physical volume

-a, --all

Change all visible physical volumes

-f, --force

Force operation

-v, --verbose

Verbose mode

INSTALL

sudo apt install lvm2

sudo dnf install lvm2

sudo pacman -S lvm2

sudo apk add lvm2

sudo zypper install lvm2

nix profile install nixpkgs#lvm2

CAVEATS

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.

HISTORY

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