16 lvextend allows you to extend the size of a logical volume. Extension
17 of snapshot logical volumes (see lvcreate(8) for information to create
18 snapshots) is supported as well. But to change the number of copies in
19 a mirrored logical volume use lvconvert(8).

22 See lvm for common options.
23
24 -l, --extents [+]LogicalExtentsNumber[%{VG|LV|FREE}]
25 Extend or set the logical volume size in units of logical
26 extents. With the + sign the value is added to the actual size
27 of the logical volume and without it, the value is taken as an
28 absolute one. The number can also be expressed as a percentage
29 of the total space in the Volume Group with the suffix %VG or
30 relative to the existing size of the Logical Volume with the
31 suffix %LV or as a percentage of the remaining free space in the
32 Volume Group with the suffix %FREE.
33
34 -L, --size [+]LogicalVolumeSize[kKmMgGtTpPeE]
35 Extend or set the logical volume size in units of megabytes. A
36 size suffix of M for megabytes, G for gigabytes, T for ter‐
37 abytes, P for petabytes or E for exabytes is optional. With the
38 + sign the value is added to the actual size of the logical vol‐
39 ume and without it, the value is taken as an absolute one.
40
41 -i, --stripes Stripes
42 Gives the number of stripes for the extension. Not applicable
43 to LVs using the original metadata LVM format, which must use a
44 single value throughout.
45
46 -I, --stripesize StripeSize
47 Gives the number of kilobytes for the granularity of the
48 stripes. Not applicable to LVs using the original metadata LVM
49 format, which must use a single value throughout.
50 StripeSize must be 2^n (n = 2 to 9)
51
53 "lvextend -L +54 /dev/vg01/lvol10 /dev/sdk3" tries to extend the size
54 of that logical volume by 54MB on physical volume /dev/sdk3. This is
55 only possible if /dev/sdk3 is a member of volume group vg01 and there
56 are enough free physical extents in it.
