       [-h|-?|--help] [--noudevsync]  [-i|--stripes  Stripes  [-I|--stripesize

       ber[%{VG|LV|PVS|FREE|ORIGIN}] | -L|--size [+]LogicalVolumeSize[bBsSkKm‐

       [-v|--verbose] LogicalVolumePath [PhysicalVolumePath[:PE[-PE]]...]

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 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, rel‐
	      ative to the existing size of the Logical Volume with the suffix
	      %LV,  of the remaining free space for the specified PhysicalVol‐
	      ume(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 Logi‐
	      cal Volume with the suffix %ORIGIN.

       -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  ter‐
	      abytes, P for petabytes or E for exabytes is optional.  With the
	      + sign the value is added to the actual size of the logical vol‐
	      ume 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
       "lvextend -L +54 /dev/vg01/lvol10 /dev/sdk3" tries to extend  the  size
       of  that	 logical volume by 54MB 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  /dev/vg01/lvol01 /dev/sdk3" tries to extend the size of that
       logical	volume	by  the	 amount	 of  free  space  on  physical	volume
       /dev/sdk3.   This is equivalent to specifying "-l +100%PVS" on the com‐
       mand line.

       "lvextend -L+16M vg01/lvol01 /dev/sda:8-9 /dev/sdb:8-9"
       tries to extend a logical volume "vg01/lvol01" by 16MB  using  physical
       extents /dev/sda:8-9 and /dev/sdb:8-9 for allocation of extents.
