SYNOPSIS

[--alloc AllocationPolicy]
[-A/--autobackup y/n] [-d/--debug] [-h/-?/--help]
[-i/--stripes Stripes [-I/--stripesize StripeSize]]
{-l/--extents [+]LogicalExtentsNumber |
-L/--size [+]LogicalVolumeSize[kKmMgGtT]}
[-t/--test]
[-v/--verbose] LogicalVolumePath [PhysicalVolumePath...]
DESCRIPTION
lvextend allows you to extend the size of a logical volume.
Extension of snapshot logical volumes (see
lvcreate(8)
for information to create snapshots) is supported as well.
OPTIONS
See lvm for common options.
- -l, --extents [+]LogicalExtentsNumber
-
Extend or set the logical volume size in units of logical extents.
With the + sign the value is added to the actual size
of the logical volume and without it, the value is taken as an absolute one.
- -L, --size [+]LogicalVolumeSize[kKmMgGtT]
-
Extend or set the logical volume size in units in units of megabytes.
A size suffix of M for megabytes, G for gigabytes or T for terabytes is
optional. With the + sign the value is added to 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 for the extension.
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.
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)
Examples
"lvextend -L +54 /dev/vg01/lvol10 /dev/sdk3" tries to extend the size of
that logical volume by 54MB on physical volume /dev/sdk3.
This is only possible if /dev/sdk3 is a member of volume group vg01 and
there are enough free physical extents in it.
