I’m fairly sure that’s not supported, like, at all. You might be able to get Rockstor running (from a source install, I think, although I never did so myself), but the whole system is based around the assumption that the FS is BTRFS. Things might break in very interesting ways.

Why are you trying to use a BTRFS-based system on a non-BTRFS system? What are you trying to achieve?
