Yes. I considered that too. What you have to weigh it up against is the management overhead: - recognising a failed disk - replacing a failed disk (which involves creating a new XFS filesystem and mounting it at the right place) - forcing a self-heal Whereas detecting a failed RAID disk is straightforward, and so is swapping it out.
