Hello,
I have logical volume group of 50GB, in which I have 2 logical volumes, LogVol01 and LogVol02, both are of 10GB.

lvresize
LVRESIZE(8) System Manager's Manual LVRESIZE(8)
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 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|PVS|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, relative to the existing size of the Logical 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 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)
