lvm2/man/lvextend.8_des
Alasdair G Kergon ca905681cc man: Revise internal man page generation process.
For each section 8 man page, a .8_gen file is created from one of:
  .8_main            - Old-style man page - content used directly
  .8_des and .8_end  - Description and end section of a generated page
  .8_pregen	     - Pre-generated page used if the generator fails

Other man sections are not generated and use the suffix .5_main or .7_main.

Developers should use 'make generate' to regenerate the .8_pregen files.

lvextend extends the size of an LV. This requires allocating logical
extents from the VG's free physical extents. If the extension adds a new
LV segment, the new segment will use the existing segment type of the LV.
Extending a copy\-on\-write snapshot LV adds space for COW blocks.
Use \fBlvconvert\fP(8) to change the number of data images in a RAID or
mirrored LV.
In the usage section below, \fB--size\fP \fISize\fP can be replaced
with \fB--extents\fP \fINumber\fP. See both descriptions
the options section.
