Actually I just checked with btrfsprogs

btrfs-map-logical is the tool that will convert logical to physical
and also give what device it's on; but the device notation is copy 1
and copy 2, so you have to infer what device that is, it's not
explicit.

Hi, Thanks for responses.
I actually need the physical addresses. FIEMAP I believe (and I
tested) gives logical address which as Andrei mentioned is useless.
I'm assuming btfs-debug-tree gives the physical addresses right? I
also need to know the compression method used on each extent and I
don't

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
13 matches
