Hi Chris, According to my understanding, COW in Btrfs services for 1) snapshots capacities 2) keeping checksum consistent with FS data, that's why nodatacow implies nodatasum. And COW will still happen for snapshots even under 'nodatacow'.
So could you please tell me what can we get from COW if not computing checksum (nodatasum)? That's to say, if some user decides to disable checksum, do you think it's fine for him to just mount with 'nodatacow'? Or there's still some reason for him to use bare 'nodatasum'?
