Переменные (Variables)
VG Volume Group name. See lvm(8) for valid names.
PV Physical Volume name, a device path under /dev. For
commands managing physical extents, a PV positional arg
generally accepts a suffix indicating a range (or multiple
ranges) of physical extents (PEs). When the first PE is
omitted, it defaults to the start of the device, and when
the last PE is omitted it defaults to end. Start and end
range (inclusive): PV[:PE-PE]... Start and length range
(counting from 0): PV[:PE+PE]...
String See the option description for information about the
string content.
Size[UNIT]
Size is an input number that accepts an optional unit.
Input units are always treated as base two values,
regardless of capitalization, e.g. 'k' and 'K' both refer
to 1024. The default input unit is specified by letter,
followed by |UNIT. UNIT represents other possible input
units: b|B is bytes, s|S is sectors of 512 bytes, k|K is
KiB, m|M is MiB, g|G is GiB, t|T is TiB, p|P is PiB, e|E
is EiB. (This should not be confused with the output
control --units, where capital letters mean multiple of
1000.)
