NAME

SYNOPSIS

9       lvresize  [--alloc AllocationPolicy] [-A/--autobackup y/n] [-d/--debug]
10       [-h/-?/--help]  [-i/--stripes  Stripes  [-I/--stripesize   StripeSize]]
11       {-l/--extents    [+]LogicalExtentsNumber[%{VG|LV|FREE}]   |   -L/--size

13       umePath [PhysicalVolumePath...]

DESCRIPTION

16       lvresize allows you to resize a logical volume.  Be careful when reduc‐
17       ing a logical volume's size,  because  data  in  the  reduced  part  is
18       lost!!!   You should therefore ensure that any filesystem on the volume
19       is shrunk first so that the extents that are to be removed are  not  in
20       use.   Resizing  snapshot logical volumes (see lvcreate(8) for informa‐
21       tion about creating snapshots) is supported as well.  But to change the
22       number of copies in a mirrored logical volume use lvconvert(8).

OPTIONS

25       See lvm for common options.
26
27       -l, --extents [+/-]LogicalExtentsNumber[%{VG|LV|FREE}]
28              Change  or  set  the  logical  volume  size  in units of logical
29              extents.  With the + or - sign the value is  added  to  or  sub‐
30              tracted  from  the actual size of the logical volume and without
31              it, the value is taken as an absolute one.  The number can  also
32              be  expressed  as  a percentage of the total space in the Volume
33              Group with the suffix %VG or relative to the  existing  size  of
34              the Logical Volume with the suffix %LV or as a percentage of the
35              remaining free space in the Volume Group with the suffix %FREE.
36
37       -L, --size [+/-]LogicalVolumeSize[kKmMgGtTpPeE]
38              Change or set the logical volume size in units of megabytes.   A
39              size  suffix  of  M  for  megabytes, G for gigabytes, T for ter‐
40              abytes, P for petabytes or E for exabytes is optional.  With the
41              +  or - sign the value is added to or subtracted from the actual
42              size of the logical volume and without it, the value is taken as
43              an absolute one.
44
45       -i, --stripes Stripes
46              Gives the number of stripes to use when extending a Logical Vol‐
47              ume.  Defaults to whatever the last segment of the Logical  Vol‐
48              ume uses.  Not applicable to LVs using the original metadata LVM
49              format, which must use a single value throughout.
50
51       -I, --stripesize StripeSize
52              Gives the  number  of  kilobytes  for  the  granularity  of  the
53              stripes.   Defaults  to whatever the last segment of the Logical
54              Volume uses.  Not applicable to LVs using the original  metadata
55              LVM format, which must use a single value throughout.
56              StripeSize must be 2^n (n = 2 to 9)
