I realize you describe a past setup, but as a fun tip, you could have used md
RAID0 for this: with different sized devices it would automatically stripe the
first 1TB of both disks, and then continue with the tail of 2TB drive as-is.
This would provide some linear speed benefit for the most part of the device,
with no change in reliability in this scheme compared to md linear.
