Hi,
I have a btrfs partions on my laptop containing / and /home. Recently I
noticed that trim (fstrim) didn't work anymore. It always tells me there
nothing to trim which can not be correct. I then tried to to run btrfsck
--repair and this is the result:
ubuntu@ubuntu:~$ sudo btrfsck /dev/sda3 --repair
enabling repair mode
Fixed 0 roots.

I get the exact same result every time I run btrfsck --repair. If the
file system irreparable or is there something I can do to save it?
