And the "rescue" commands tell you not to use them unless you've been blessed by someone on a mailing list, and that they can actually cause MORE damage. I was using BTRFS on my workstation and all of a sudden some garbage got written to the extent-tree, and it was toast. Never using BTRFS again. I had backups and was able to recover 99.99%, but the recuse tools were garbage. I finally killed it after it had spent a month, from July 4 until August 4, doing apparently nothing. And this was this year. This was a normal desktop configuration, single drive. I wasn't using any of the real features of the FS other than COW.
