Checksum capabilities with btrfs on top of mdraid?
As I understand, readynas OS6 implements btrfs on top of an mdraid volume because native raid-support in btrfs is still a bit experimental (introduced 2013). How does this affect the checksum capabili...
Bit rot is indeed a concern. Never seen one though. Never seen any countermeasure in up to mid-sized enterprise either. Maybe it's more seen with high speed transactional data or with long term storage (tapes).
What I'm saying is that you may end up with more trouble messing with the NAS than you could actually experience with bit rot. Messing with the raid can actually get you boot problem, disk adding errors, disk replacing problems, scrub/defrag buttons broken. If you really want to go the full BTRFS way i would advise to get a fresh Debian and do it all by yourself but a NAS doesn't seem a good place to experiment to me.
The way I see things, you may ask Netgear what they have in place to deal with it, use what you can that's already integrated on the NAS, maybe do a little tweaking but rebuilding a raid is definitely more than just that.
You can always try with a VM though, seek "OS6 tips and tricks" in "user submitted tips" forums, I think I posted the link in it.
