Hi, I am working on a project with Btrfs and I was wondering if there is any way to see the disk layout of the btrfs image. Let's assume I have a read-only btrfs image with compression on and only using one disk (no raid or anything). Is it possible to get a set of offset-lengths for each file or metadata parts of the image. I know there is an unfinished documentation for On-disk Formant in here: https://btrfs.wiki.kernel.org/index.php/On-disk_Format But it is not complete and does not show what I am looking for. Is there any other documentation on this? Is there any public API that I can use to get this information. For example can I iterate on all files starting from the root node and get all offset-lengths? This way any part that doesn't come can be assumed as metadata. I don't really care what is inside the metadata, I just want to know their offset-lengths in the file system. Thank you, Amin. -- 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
