device removal (negative value) or device addition (positive

RAID levels 4/5/6 allow for addition of devices (metadata
and data device tupel), raid10_near and raid10_offset only
allow for device addtion. raid10_far does not support any
and data device tuple), raid10_near and raid10_offset only

A minimum of devices have to be kept to enforce resilience,
which is 3 devices for raid4/5 and 4 devices for raid6.
