as far as I know, you can put disks of different sizes in a mirror vdev, you’ll just obviously be limited to the size of the smaller disk. Is that not what OC

Is that not what OC is asking for?
- gray_-_wolf 4y agoBtrfs' RAID1 works bit differently. It ensures every block (1GB by default I believe) is present on two devices. So, if for example, you have 2x 1TB and 1x 2TB drive, you get 2 TB of usable space. It is arguably not the most useful property in enterprise setting, but helps to stay on budget on home projects, since I can just use random drives laying around without any further requirements on the matching of the sizes.
