NAME

pvresize - resize a disk or partition in use by LVM2

SYNOPSIS

pvresize [-d|--debug] [-h|--help] [-t|--test] [-v|--verbose] [--setphysicalvolumesizesize] PhysicalVolume [PhysicalVolume...]

DESCRIPTION

pvresize resizes PhysicalVolume which may already be in a volume group and have active logical volumes allocated on it.

OPTIONS

See lvm(8) for common options.
TagDescription
--setphysicalvolumesize size
  Overrides the automatically-detected size of the PV. Use with care, or prior to reducing the physical size of the device.

EXAMPLES

Expand the PV on /dev/sda1 after enlarging the partition with fdisk:

pvresize /dev/sda1

Shrink the PV on /dev/sda1 prior to shrinking the partition with fdisk (ensure that the PV size is appropriate for your intended new partition size):

pvresize --setphysicalvolumesize 40G /dev/sda1

RESTRICTIONS

pvresize will refuse to shrink PhysicalVolume if it has allocated extents after where its new end would be. In the future, it should relocate these elsewhere in the volume group if there is sufficient free space, like pvmove does.

pvresize won’t currently work correctly on LVM1 volumes or PVs with extra metadata areas.
