SYNOPSISlvresize [--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...]
DESCRIPTIONlvresize 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.
OPTIONS
See lvm for common options.
-l, --extents [+/-]LogicalExtentsNumber
Change or set the logical volume size in units of logical
extents. With the + or - sign the value is added to or sub‐
tracted from the actual size of the logical volume and without
it, the value is taken as an absolute one.
-L, --size [+/-]LogicalVolumeSize[kKmMgGtT]
Change or set the logical volume size in units of megabytes. A
size suffix of M for megabytes, G for gigabytes or T for ter‐
abytes 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)
