NAME

       lvresize - resize a logical volume


SYNOPSIS

       lvresize  [--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

       lvresize allows you to resize a logical volume.  Be careful when reduc-
       ing a logical volume’s size,  because  data  in  the  reduced  part  is
       lost!!!   You should therefore ensure that any filesystem on the volume
       is shrunk first so that the extents that are to be removed are  not  in
       use.   Resizing  snapshot logical volumes (see lvcreate(8) for informa-
       tion about creating snapshots) is supported as well.


OPTIONS

       See lvm for common options.

       -l, --extents [+/-]LogicalExtentsNumber
              Change or set the  logical  volume  size  in  units  of  logical
              extents.   With  the  +  or - sign the value is added to or sub-
              tracted from the actual size of the logical volume  and  without
              it, the value is taken as an absolute one.

       -L, --size [+/-]LogicalVolumeSize[kKmMgGtT]
              Change  or set the logical volume size in units of megabytes.  A
              size suffix of M for megabytes, G for gigabytes or  T  for  ter-
              abytes  is optional.  With the + or - sign the value is added to
              or subtracted from 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 to use when extending a Logical Vol-
              ume.  Defaults to whatever the last segment of the Logical  Vol-
              ume uses.  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.   Defaults  to whatever the last segment of the Logical
              Volume uses.  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)
