What does the word "unfunctional" mean? Unable to mount?

Unless there is some bug in btrfs-progs 4.4, your fs should be mostly OK. > checking quota groups > Ignoring qgroup relation key 310 [snip] > Ignoring qgroup relation key 71776119061217590 Just a lot of qgroup relation key problems. Not a big problem, especially considering you're using older kernel without proper qgroup fixes. Just in case, please run "btrfs check" with latest btrfs-progs (v4.17.1) to see if it reports extra error. Despite that, if the fs can be mounted RW, mount it then execute "btrfs quota disable <mnt>" should disable quota and solves the problem.
