Since each non-inlined file will occupy a minimum of 4k, you may find that inlining will still save space even if it is duplicated. Even if they are duplicated in the metadata under RAID1, inlining a bunch of 256 byte files will still be more space efficient than storing them as regular files. But if most of the files are in the 2k-3k range, you may be more efficient to store them as files. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
