SYNOPSISlvextend [--alloc AllocationPolicy] [-A/--autobackup y/n] [-d/--debug]
[-h/-?/--help] [-i/--stripes Stripes [-I/--stripesize StripeSize]]
{-l/--extents [+]LogicalExtentsNumber | -L/--size [+]LogicalVolume‐
Size[kKmMgGtT]} [-t/--test] [-v/--verbose] LogicalVolumePath [Physi‐
calVolumePath...]
DESCRIPTIONlvextend 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.
