Hello! I have a problem with btrfs device. Shows 355Gb free space. Done scrub on that. It shows that there is no space left on device. Doing simple operations (mkdir, touch, find) are extremely slow. Checking btrfsck show add_data_backref error (see below). Do you think I could do : btrfs check —repair ? root@gamma:~# btrfsck -p /dev/sda1 Checking filesystem on /dev/sda1 UUID: 666a7089-d716-44ff-8081-56b969b58eff cmds-check.c:4869: add_data_backref: Assertion `!back` failed. root@gamma:~# df -h /dev/sda1 Filesystem Size Used Avail Use% Mounted on /dev/sda1 1.9T 1.5T 355G 81% /tmp/rescue root@gamma:~# btrfs --version btrfs-progs v4.7.3
