NAME
lvresize - resize a logical volume
SYNOPSIS
lvresize [--alloc AllocationPolicy] [-A|--autobackup y|n] [-d|--debug]
[-h|-?|--help] [-i|--stripes Stripes [-I|--stripesize StripeSize]]
{-l|--extents [+]LogicalExtentsNumber[%{VG|LV|PVS|FREE}] | -L|--size
[+]LogicalVolumeSize[kKmMgGtT]} [-t|--test] [-v|--verbose] LogicalVol-
umePath [PhysicalVolumePath...]
DESCRIPTION
lvresize allows you to resize a logical volume. Be careful when reduc-
ing a logical volume's size, because data in the reduced part is
lost!!! You should therefore ensure that any filesystem on the volume
is shrunk first so that the extents that are to be removed are not in
use. Resizing snapshot logical volumes (see lvcreate(8) for informa-
tion about creating snapshots) is supported as well. But to change the
number of copies in a mirrored logical volume use lvconvert(8).
OPTIONS
See lvm for common options.
-l, --extents [+|-]LogicalExtentsNumber[%{VG|LV|PVS|FREE}]
Change or set the logical volume size in units of logical ex-
tents. With the + or - sign the value is added to or subtracted
from the actual size of the logical volume and without it, the
value is taken as an absolute one. The number can also be ex-
pressed as a percentage of the total space in the Volume Group
with the suffix %VG, relative to the existing size of the Logi-
cal Volume with the suffix %LV, as a percentage of the remaining
free space of the PhysicalVolumes on the command line with the
suffix %PVS, or as a percentage of the remaining free space in
the Volume Group with the suffix %FREE.
-L, --size [+|-]LogicalVolumeSize[kKmMgGtTpPeE]
Change or set the logical volume size in units of megabytes. A
size suffix of M for megabytes, G for gigabytes, T for ter-
abytes, P for petabytes or E for exabytes is optional. With the
+ or - sign the value is added to or subtracted from the actual
size of the logical volume and without it, the value is taken as
an absolute one.
-i, --stripes Stripes
Gives the number of stripes to use when extending a Logical Vol-
ume. Defaults to whatever the last segment of the Logical Vol-
ume uses. Not applicable to LVs using the original metadata LVM
format, which must use a single value throughout.
-I, --stripesize StripeSize
Gives the number of kilobytes for the granularity of the
stripes. Defaults to whatever the last segment of the Logical
Volume uses. Not applicable to LVs using the original metadata
LVM format, which must use a single value throughout.
StripeSize must be 2^n (n = 2 to 9)
