 +
 +DESCRIPTION
 +       ​lvextend allows you to extend the size of a logical volume. ​ Extension of snapshot logical volumes (see lvcreate(8) for  informa‐
 +       ​tion ​ to  create ​ snapshots) ​ is  supported ​ as well.  But to change the number of copies in a mirrored logical volume use lvcon‐
 +       ​vert(8).
 +
 +OPTIONS
 +       See lvm(8) for common options.
 +
 +       -f, --force
 +              Proceed with size extension without prompting.
 +
 +       -l, --extents [+]LogicalExtentsNumber[%{VG|LV|PVS|FREE|ORIGIN}]
 +              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.  The total number of physical extents
 +              allocated will be greater than this, for example, if the volume is mirrored. ​ The number can also be expressed as  a  per‐
 +              centage ​ 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, of the remaining free space for the specified PhysicalVolume(s) 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 ​ 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 upper limit for
 +              the total number of physical extents to be allocated (including extents used by any mirrors, for example). ​ The  code  may
 +              currently allocate more space than you might otherwise expect.
 +
 +       -L, --size [+]LogicalVolumeSize[bBsSkKmMgGtTpPeE]
 +              Extend ​ 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 + 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)
 +
 +       -n, --nofsck
 +              Do  not  perform fsck before extending filesystem when filesystem requires it. You may need to use --force to proceed with
 +              this option.
 +
 +       ​--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.
 +
 +       -r, --resizefs
 +              Resize underlying filesystem together with the logical volume using fsadm(8).
 +
 +       ​--use-policies
 +              Resizes the logical volume according to configured policy. See lvm.conf(5) for some details.
 +
 +
 +Examples
 +       ​Extends the size of the logical volume "​vg01/​lvol10"​ by 54MiB 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:
 +
 +       ​lvextend -L +54 /​dev/​vg01/​lvol10 /dev/sdk3
 +
 +       ​Extends ​ the size of logical volume "​vg01/​lvol01"​ by the amount of free space on physical volume /dev/sdk3. This is equivalent to
 +       ​specifying "-l +100%PVS"​ on the command line:
 +
 +       ​lvextend /​dev/​vg01/​lvol01 /dev/sdk3
 +
 +       ​Extends a logical volume "​vg01/​lvol01"​ by 16MiB using physical extents /​dev/​sda:​8-9 and /​dev/​sdb:​8-9 for allocation of extents:
 +
 +       ​lvextend -L+16M vg01/lvol01 /​dev/​sda:​8-9 /​dev/​sdb:​8-9
