Oh right, world wide computer part shortage. All hard drives that will be produced in 2026 are already bought and paid for.

FML.

Okay, ended up with 3 16TB drives and 3 22TB drives. I couldn't get 6 of anything in any reasonable time frame or price.

It's going to be a heck of a progress to replace the 4xRAID5 and 2xRAID1 arrays.

I need to rebuild the RAID1 twice, then grow it to the new size. Then I'll have enough room to migrate the RAID5 data over to it. Then I'll just build a new 3xRAID5, move that data back. Add another drive to the RAID1 and make it a second 3xRAID5.

Should only take me 2.4 years.

@janusfox I hope you're on btrfs or something and not ZFS. Heard ZFS really doesn't like mixed drive sizes (but we've never tried it, and even though we've dabbled in btrfs we've never done RAID).
@Ylfingr I have two different raid arrays, in fact.

@janusfox Fancy!

(we only have one bulk-storage disk in the first place)
