Wouldn't it be at least slightly risky to pull all your spares plus one of your data drives for the duration of a rebuild?
Yes. Therefore it's not really recommended.
It's a pity that ONTAP doesn't support some sort of "planned disc failure". The sort of thing I have in mind is duplication of the parity disc or one of the data discs of a RAID group on a spare disc, without having to fail the original one first. Then a failure of another disc in the group during the process could cause this duplication to be abandoned and the more urgent condition to be dealt with instead.
This would be useful when taking discs out of service that are showing problems but haven't actually failed yet.
