redundancy or enhanced I/O performance. See also volume, spanned volume,
RAID 0, RAID 1. Also known as a container.

created. When an array is deleted, the space that it used is returned to the
available space pool.

by all arrays to see if the disks can return data from the blocks. See also consis-
