 +
 +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
