Btrfs-progs' version is irrelevant. The problem is the send side generating incorrect paths in the send stream (as I mentioned earlier), so it's exclusively a problem in the kernel. > Second > is that I have been able to recreate this issue three times over a period of > two to three days (tring again with 4.2.3).

If you can find out what happened to the directory/file in question between the parent and send snapshots (was it renamed/moved? was it deleted and then a new one with the same name/location created?) that helps. Otherwise looking at btrfs-debug-tree and see the trees for each snapshot helps too, but you need to figure out the number of the inode where it's failing (sometimes btrfs receive -vv is enough to figure this out). thanks > > Meanwhile I've been falling back to rsync which always works but is so much > slower. > > TIA > Ed > On Sunday, October 25, 2015 9:42:54 AM EDT, Filipe Manana wrote: >> >> On Sun, Oct 25, 2015 at 1:38 PM, Ed Tomlinson <e...@aei.ca> wrote: >>> >>> Filipe, >>> >>> Its still not perfect.
