Josef, it looks like the tracking code is losing some bytes ;) The
total bytes in the space info doesn't add up to the other numbers in
this data. It is worth mentioning that he's doing nodatacow.
Definitely a btrfs bug, so we can trim ext4 off the list from now on,
full quote below for Josef.

I'm still keeping two partitions with btrfs with such failure(i have 9 HDD's,
others i use now ext4, they do job fine for my squid, except lacking dynamic
inode allocation), do you want me to keep partitions as is more time?
