lvresize(8) - Linux man page
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|FREE}] | -L/--size [+]LogicalVolumeSize[kKmMgGtT]}
[-t/--test] [-v/--verbose] LogicalVolumePath [PhysicalVolumePath...]
Description
lvresize allows you to resize a logical volume. Be careful when reducing 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 information 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|FREE}]
- Change or set the logical volume size in units of logical extents. 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 expressed as a percentage of the total space in the Volume Group
with the suffix %VG or relative to the existing size of the Logical Volume with the suffix %LV 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 terabytes, 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 Volume. 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.
- -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)
