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  |  -L/--size  [+]LogicalVolume-
       Size[kKmMgGtT]} [-t/--test]  [-v/--verbose]  LogicalVolumePath  [Physi-
       calVolumePath...]


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.


OPTIONS

       See lvm for common options.

       -l, --extents [+]LogicalExtentsNumber
              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.

       -L, --size [+]LogicalVolumeSize[kKmMgGtT]
              Extend or set the logical volume  size  in  units  in  units  of
              megabytes.  A size suffix of M for megabytes, G for gigabytes or
              T for terabytes 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)


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.
