    Jesus the beta is really buggy for me, It just removed my primary cache drive, can anyone help me as how to get I t back/ how to downgrade back to 6.9.3 stable?

    I had a backup from 2 days ago and ended up going that route after going back to unraid 6.8.3 that also stopped my issues with plex crashing/freezing the server

    It's not the superblock, first error lines are the important ones, it's extent tree corruption, loos like part of it was wiped/trimmed, if it's just the extent tree btrfs restore should be able to recover most of your data.

    Neither of the three options given worked in my situation
