Manual Section... (8) - page: pvresize
NAMEpvresize - resize a disk or partition in use by LVM2
SYNOPSISpvresize [-d|--debug] [-h|--help] [-t|--test] [-v|--verbose] [--setphysicalvolumesizesize] PhysicalVolume [PhysicalVolume...]
DESCRIPTIONpvresize resizes PhysicalVolume which may already be in a volume group and have active logical volumes allocated on it.
OPTIONSSee 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.
EXAMPLESExpand the PV on /dev/sda1 after enlarging the partition with fdisk:
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
RESTRICTIONSpvresize 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.
