In this configuration btrfs can't heal checksum errors, but will still detect them if they appear. btrfs now also has built-in RAID5 and RAID6 which *can* heal errors, but that's still way too immature for being actually used. In fact one may consider btrfs as a whole to be not mature enough yet, but in my experience without using fancy cutting edge features like RAID it generally works, and I don't remember seeing mailing list reports of any data loss or corruption from anyone in a long time. -- With respect, Roman
