My current home lab had 2x4tb drives in Raid 1. Today’s goal is converting to Raid 5 and adding 4x4tb drives to expand storage without losing data. THIS IS NOT A GUIDE, unless it works.

I would recommend move to BTRFS or ZFS. Easyer and safer to work with.
Don’t use the RAID56 functionality of BTRFS, the official docs still list it as unstable. Apart from that it’s pretty good.

ZFS for “RAID” is fine. Btrfs for a single disk (or on top of mdraid or hardware raid) is also fine.
I am running BTRFS Raid 6. i have no problems with it. You need a UPS to avoid transient errors.

Agreed. I’m using it as a mirror, and I’ll probably add another mirror once I run out of space.
Still? Good God, it’s been like 15 years.
Turns out the old gag “You can’t get there from here; You have to go somewhere else and start” is actually true for btrfs’s RAID support.
