NAME

        lvextend - extend the size of a logical volume

SYNOPSIS

        lvextend  [--alloc AllocationPolicy] [-A/--autobackup y/n] [-d/--debug]
        [-h/-?/--help]  [-i/--stripes  Stripes  [-I/--stripesize   StripeSize]]
        {-l/--extents    [+]LogicalExtentsNumber[%{VG|LV|FREE}]   |   -L/--size
        [+]LogicalVolumeSize[kKmMgGtT]} [-t/--test] [-v/--verbose]  LogicalVol‐
        umePath [PhysicalVolumePath...]

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.
 
        -l, --extents [+]LogicalExtentsNumber[%{VG|LV|FREE}]
               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  or
               relative  to  the  existing  size of the Logical Volume with the
               suffix %LV or as a percentage of the remaining free space in the
               Volume Group with the suffix %FREE.
 
        -L, --size [+]LogicalVolumeSize[kKmMgGtTpPeE]
               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)

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.
