NAME

       lvreduce - reduce the size of a logical volume


SYNOPSIS

       lvreduce [-A/--autobackup y/n] [-d/--debug] [-f/--force] [-h/-?/--help]
       {-l/--extents  [-]LogicalExtentsNumber  |  -L/--size  [-]LogicalVolume-
       Size[kKmMgGtT]} [-t/--test] [-v/--verbose] LogicalVolume[Path]


DESCRIPTION

       lvreduce allows you to reduce the size of a logical volume.  Be careful
       when reducing a logical volume’s size, because data in the reduced part
       is lost!!!
       You  should  therefore  ensure  that  any  filesystem  on the volume is
       resized before running lvreduce so that the  extents  that  are  to  be
       removed are not in use.
       Shrinking  snapshot logical volumes (see lvcreate(8) for information to
       create snapshots) is supported as well.
       Sizes will be rounded if necessary - for example, the volume size  must
       be an exact number of extents and the size of a striped segment must be
       a multiple of the number of stripes.


OPTIONS

       See lvm for common options.

       -f, --force
              Force size reduction without any question.

       -l, --extents [-]LogicalExtentsNumber
              Reduce or set the  logical  volume  size  in  units  of  logical
              extents.   With the - sign the value will be subtracted from the
              logical volume’s actual size and without it the will be taken as
              an absolute size.

       -L, --size [-]LogicalVolumeSize[kKmMgGtT]
              Reduce  or  set  the logical volume size in units of megabyte by
              default.  A size suffix of k for kilobyte, m for megabyte, g for
              gigabyte  or  t  for  terabyte is optional.  With the - sign the
              value will be subtracted from the logical volume’s  actual  size
              and without it it will be taken as an absolute size.


Example

       "lvreduce -l -3 vg00/lvol1" reduces the size of logical volume lvol1 in
       volume group vg00 by 3 logical extents.
