But BTRFS does checksums on all reads and solves the problem of corrupt data - as long as you don't have 2 corrupt sectors in matching blocks. Yeah. I'm not sure though if openSUSE 13.2 prevents users from creating btrfs raid1 volumes entirely, or if it's just an install time limitation. I know that Fedora's installer won't allow the user to create Btrfs on LVM, and it probably doesn't allow it on md raid either. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
