The size of a volume is automatically adjusted conforming to the following conditions.
When creating a volume into the group that a keep disk belongs to [EFI]
A volume is created in the size calculated by rounding-up the size specified when creating the volume to a multiple of the keep disk's cylinder size.
(Example)
If the keep disk's cylinder size is 8 MB (= 16,384 blocks) and 20 MB (= 40,960 blocks) is specified as the size of a volume when it is created, the size is rounded to a multiple of 16,384 blocks, and a volume with 49,152 blocks (= 24 MB) is created.
When creating a volume into a stripe group
A volume is created in the size calculated by rounding-up the size specified when creating the volume to a common multiple of (stripe width) * (stripe column number) and the cylinder size (32,768 blocks = 16 MB).
(Example)
If the stripe width is 32, the number of the stripe columns is 3 and 20 MB (= 40,960 blocks) is specified as the size of a volume when it is created, the size is rounded to a common multiple of 96 (= 32 * 3) blocks and 32,768 blocks, and a volume with 98,304 blocks (= 48 MB) is created.
When creating other volumes
A volume is created in the size calculate by rounding-up the size specified when creating the volume to a multiple of the cylinder size (32,768 blocks = 16 MB).
(Example)
If 20 MB (= 40,960 blocks) is specified as the size of a volume when it is created, the size is rounded to a multiple of 32,768 blocks, and a volume with 65,536 blocks (= 32 MB) is created.
