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 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.
