A、Allows the mirror partitions to spread across a maximum number of disks.

B、Allows the copy of a partition to be on the same physical volume as the mirrored partition.

C、Prevents partitions allocated to one logical volume mirror from sharing a physical volume with partitions from another logical volume mirror.

D、Forces copies of logical partitions to be housed on different physical volumes， while allowing a single physical volume to be shared by logical volume mirrors.
