mkfs.btrfs /dev/sdb
mkdir /tmp/mnt
mount /dev/sdb /tmp/mnt
cd /tmp/mnt
btrfs quota enable .
btrfs subvol create foo
btrfs qgroup create 1/0
btrfs qgroup assign 0/257 1/0
btrfs subvol snapshot foo bar
btrfs qgroup assign 0/258 1/0
cd ..
umount /dev/sdb
mount /dev/sdb /tmp/mnt
# Still mountable!
cd mnt
btrfs qgroup destroy 1/0
cd ..
umount /dev/sdb
mount /dev/sdb /tmp/mnt
# Oops, no longer mountable, even in recovery mode!
