kernel 4.2.6-301.fc23.x86_64
btrfs-progs-4.2.2-1.fc23.x86_64
This is a new one for me. Two new Btrfs volumes (one single profile,
one 2x raid1) both created with this btrfs-progs. And then
[root@f23a chrisbackup]# btrfs send everything-20150922/ | btrfs
receive /mnt/br1-500g/
At subvol everything-20150922/
At subvol everything-20150922
ERROR: did not find source subvol.
There are no kernel messages.
[root@f23a chrisbackup]# du -sh everything-20150922/
324G everything-20150922/
[root@f23a chrisbackup]# du -sh /mnt /b
[root@f23a chrisbackup]# du -sh /mnt/br1-500g/everything-20150922/
322G /mnt/br1-500g/everything-20150922/
HUH, looks like 2G is missing on the receive side. So it got
interrupted for some reason?
btrfs check (v4.3.1) comes up clean on the source, as does a scrub.
So should I retry with -v on the send or the receive side or both?

Files are definitely missing. -v reveals no new information. So I'm confused.
Next, I switched to kernel 4.4rc5 and btrfs-progs 4.3.1 and I'm not
seeing this problem. Same file systems, same subvolume.
