Yes, that’s the only reason. You can mix drive sizes and still have a dedicated parity drive to rebuild from in case things go poorly. I am aware that it’s basically LVM with extra steps, but for a NAS I just want it to be as appliance-like as possible.
Still using Scale at work, though - that use case is different.
Proxmox 9 dropped too, their major releases coincide with Debian’s. Upgrade process on a single standalone box was completely uneventful; I’ll be trying a 9-node cluster on Monday.
