See lvm(8) for valid names.\n\nString See the option description for information about the string content.\n\nSize[UNIT]\nSize is an input number that accepts an optional unit.  Input units are always treated\nas base two values, regardless of capitalization, e.g. 'k' and 'K' both refer to 1024.\nThe  default  input  unit  is specified by letter, followed by |UNIT.  UNIT represents\nother possible input units: b|B is bytes, s|S is sectors of 512 bytes, k|K is KiB, m|M\nis MiB, g|G is GiB, t|T is TiB, p|P is PiB, e|E is EiB.  (This should not be  confused\nwith the output control --units, where capital letters mean multiple of 1000.)\n",
