what does /proc/mounts say about the applied options? do you see nodatasum and nodatacow there? afaik most (if not all) mount options affect the whole filesystem including any subvolume mounts. having per-subvol options is possible, just not implemented. david -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
