DESCRIPTION

       lvextend  allows  you to extend the size of a logical volume.  Extension of snapshot logical volumes (see
       lvcreate(8) for information to create snapshots) is supported as well.   But  to  change  the  number  of
       copies in a mirrored logical volume use lvconvert(8).

OPTIONS

       See lvm(8) for common options.

       --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.

       -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 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, 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.

       -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)

       -f, --force
              Proceed with size extension without prompting.

       -n, --nofsck
              Do not perform fsck before extending 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).

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
