lvm2/man/lvreduce.8_des

lvreduce reduces the size of an LV. The freed logical extents are returned
to the VG to be used by other LVs. A copy-on-write snapshot LV can also
be reduced if less space is needed to hold COW blocks. Use
\fBlvconvert\fP(8) to change the number of data images in a RAID or
mirrored LV.
.P
Be careful when reducing an LV's size, because data in the reduced area is
lost. Ensure that any file system on the LV is resized \fBbefore\fP
running lvreduce so that the removed extents are not in use by the file
system.
.P
Sizes will be rounded if necessary. For example, the LV size must be an
exact number of extents, and the size of a striped segment must be a
multiple of the number of stripes.
.P
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.

man-generator/man/help: simplify hyphen escaping Commits a29bb6a14b5e920092495fb9a1623e527d22daac ... 5c199d99f4dc9911d62673baba7643ea649ffe64 narrowed down on addressing the escaping of hyphens in the dynamic creation of manuals whilst avoiding them in creating help texts. This lead to a sequence of slipping through hyphens adrressed by additional patches in aforementioned commit series. On the other hand, postprocessing dynamically man-generator created and statically provided manuals catches all hyphens in need of escaping. Changes: - revert the above commits whilst keeping man-generator streamlining and the detection of any '\' when generating help texts in order to avoid escapes to slip in - Dynamically escape hyphens in manaual pages using sed(1) in the respective Makefile targets - remove any manually added escaping on hyphens from any static manual sources or headers 2017-03-27 16:45:48 +02:00			`to the VG to be used by other LVs.

man/help: rework extents and size output Clean up and correct the details around --extents and --size. lvcreate/lvresize/lvreduce/lvextend all now display the extents option in usages. The Size and Number value variables for --size and --extents are now displayed without the [+\|-] prefix for lvcreate. 2017-03-03 14:21:36 -06:00			`the options section.`
