This may be a silly question, but if your raid is currently working, why not remove the spare drive from your current array, pull the hardware from the machine, install your 2 bigger drives, set them up as a mirrored raid, copy all your data across. Then once copied and verified that you have all you need if you want you can retire your older drives or take whatever next steps you wish.
That way the only thing you have to worry about with regard to the spare is removing it from the array. Lorne Tyndale > > > Current server setup is raid1 with three drives.
