pvresize

PVRESIZE(8)						      System Manager's Manual						       PVRESIZE(8)

NAME

       pvresize - resize a disk or partition in use by LVM2

SYNOPSIS

       pvresize [-d|--debug] [-h|--help] [-t|--test] [-v|--verbose] [--version] [--setphysicalvolumesize size] 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.

       --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 parti-
       tion 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  relo-
       cate 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.
