Instantaneous read-only copy of an array at a precise point in time.
spanned volume
A simple volume that spans two or more drives.

T
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.
V
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.
