Date: Sun, 19 May 2013 18:31:14 +0100 Message-ID: Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Sender: linux-btrfs-owner@vger.kernel.org List-ID: Just a random Sunday afternoon thought: We've got some rather nice variations on the block-level RAID schemes but instead being implemented at the filesystem level in btrfs... Could the btrfs RAID be coded to be general so that a filesystem stack could be set up whereby the filesystem level raids could be used for ANY filesystem? So for example, we could have the stack: filesystem level RAID | V filesystem | V Block level So, an interesting variation could be to have filesystem level raid operating on ext4 or nilfs or whatever... Would that be a sensible idea? Regards, Martin
