Hello, I have a failure when mounting btrfs.
> mount -oro,recovery /dev/sda2 sda2_btrfs > mount: /dev/sda2: can't read superblock The kernel log is here http://pastebin.com/tHihHT92 and at the bottom of the email I must admit I did the error of running btrfs check --repair at some point, not knowing this was not a good idea. I run ubuntu 16.04 with kernel 4.4.0-36-generic .
