Thanks for the tip, Christopher. The document [1] you mentioned is an absolute must-read for anyone migrating from a non-RAID to RAID-1 storage system. The document's title suggests it's Debian specific, but the vast majority of it is distribution agnostic. It's up to date, using the modern mdadm tool; many documents I read still referred to raidtools. The migration process went quite flawlessly! Thanks to all those that helped.
