Hello For reference please see this post. https://mail-archive.com/linux-btrfs@vger.kernel.org/msg58461.html Please note that I downgraded to btrfs-progs 4.6.1 as advised.
After exchanging the malfunctioning drive I re-created the filesystem and restored the backup from my NAS. (I didnt entirely trust the filesystem after so many errors) On completing the restoration I manually started scrubbing, which ended with hundreds of checksum and read errors on /dev/sda. The drive checks out fine in smart and passed through all scheduled SMART Self-Tests. The model is not identical to the two drives recently added to the system - the new drives are WD Blue, the four original ones are WD Greens. I have resetted the output from btrfs dev stats and restarted the scrubbing process. I am unsure how to interpret or explain the errors of the last scrub run. I scrubbed regularly each month for nearly three years and never had any errors. I would be grateful for any advice how to proceed.
