-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  sup‐
-       ported as well.  But to change the number of copies in a mirrored logical volume use lvconvert(8).
-OPTIONS
-       See lvm(8) for common options.
-       -f, --force
-              Force resize without prompting even when it may cause data loss.
-       -n, --nofsck
-              Do  not  perform  fsck before resizing filesystem when filesystem requires it. You may need to use --force to proceed with
-              this option.
-       -r, --resizefs
-              Resize underlying filesystem together with the logical volume using fsadm(8).
-       -l, --extents [+|-]LogicalExtentsNumber[%{VG|LV|PVS|FREE|ORIGIN}]
-              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.  The total num‐
-              ber of physical extents affected will be greater than this if, for example, the volume is mirrored.  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, as a percentage of the remaining free space in the Volume Group with the suffix %FREE, or (for
-              a snapshot) as a percentage of the total space in the Origin Logical Volume with the suffix %ORIGIN.  The resulting  value
-              is  rounded  downward  for  the subtraction otherwise it is rounded upward.  N.B. In a future release, when expressed as a
-              percentage with PVS, VG or FREE, the number will be treated as an approximate total number of physical extents to be allo‐
-              cated or freed (including extents used by any mirrors, for example).  The code may currently allocate or remove more space
-              than you might otherwise expect.
-       -L, --size [+|-]LogicalVolumeSize[bBsSkKmMgGtTpPeE]
-              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 or subtracted from the
-              actual size of the logical volume and rounded to the full extent size 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.
-       --poolmetadatasize [+]MetadataVolumeSize[bBsSkKmMgG]
-              Change or set the thin pool metadata logical volume size.  With the + sign the value is added to the actual  size  of  the
-              metadata  volume  and rounded to the full extent size and without it, the value is taken as an absolute one.  Maximal size
-              is 16GiB. Default unit is megabytes.
-       -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) for metadata in LVM1 format.  For metadata in LVM2 format, the stripe size may be a
-              larger power of 2 but must not exceed the physical extent size.
-       --noudevsync
-              Disable udev synchronisation. The process will not wait for notification from udev.  It will continue irrespective of  any
-              possible  udev processing in the background.  You should only use this if udev is not running or has rules that ignore the
-              devices LVM2 creates.
-EXAMPLES
-       Extend a logical volume vg1/lv1 by 16MB using physical extents /dev/sda:0-1 and /dev/sdb:0-1 for allocation of extents:
-       lvresize -L+16M vg1/lv1 /dev/sda:0-1 /dev/sdb:0-1
