●

stripe size

The amount of data in each section of a striped array.

striped array

See

RAID 0

RAID 10

task

An operation that occurs only on the RAID controller, asynchronous to all other operations; for example,

initializing a disk or verifying an array. Some tasks can take an extended period of time, particularly if the

RAID controller is also performing intensive data I/O while the task is running.

verify

Low-level check that a drive, logical device, or hot spare is good. In a RAID 1, verify is a low-level check that

contents of both members’ segments are consistent and, optionally, corrects errors while assuming that the

master drive is correct. In a simple volume, verify performs a low-level check that the whole drive can be

read.

volume
