|
|
.SH DESCRIPTION
|
|
pvresize resizes
|
|
.I PhysicalVolume
|
|
which may already be in a volume group and have active logical volumes
|
|
allocated on it.
|
|
.SH OPTIONS
|
|
See \fBlvm\fP(8) for common options.
|
|
.TP
|
|
.BI \-\-setphysicalvolumesize " size"
|
|
Overrides the automatically-detected size of the PV. Use with care, or
|
|
prior to reducing the physical size of the device.
|
|
.SH EXAMPLES
|
|
Expand the PV on /dev/sda1 after enlarging the partition with fdisk:
|
|
.sp
|
|
.B pvresize /dev/sda1
|
|
.sp
|
|
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):
|
|
.sp
|
|
.B pvresize \-\-setphysicalvolumesize 40G /dev/sda1
|
|
.sp
|
|
.SH RESTRICTIONS
|
|
pvresize will refuse to shrink
|
|
.I 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
|
|
.B pvmove
|
|
does.
|
|
.sp
|
|
.B pvresize
|
|
won't currently work correctly on LVM1 volumes or PVs with extra
|
|
metadata areas.
