[email protected] Posted October 30, 2020 Share Posted October 30, 2020 I cant update my dockers. Plex stopped working. I think it cant write to the transcode folder? Based on my googling it is a BFRS cache pool issue. But I am a little out of my element on how to fixit. I tried to do a shutdown. but it couldn't get past syncing so i did an unclean shutdown and the cache drive was writable for a while. I deleted ~400Gb of stuff off of it. Then started a parity check, btrfs balance, and btrfs scrub with repair corrupted blocks checked. A couple of hours later the issue was back. Balance status Data, RAID1: total=742.00GiB, used=347.72GiB System, RAID1: total=32.00MiB, used=160.00KiB Metadata, RAID1: total=4.00GiB, used=1.23GiB GlobalReserve, single: total=369.34MiB, used=0.00B No balance found on '/mnt/cache' btrfs scrub status: UUID: f2db4662-24b4-4b09-8f87-932fdcd369dc Scrub started: Thu Oct 29 22:39:46 2020 Status: aborted Duration: 0:19:05 Total to scrub: 697.90GiB Rate: 228.39MiB/s Error summary: csum=2 Corrected: 0 Uncorrectable: 2 Unverified: 0 Oct 30 00:04:12 UNRAID kernel: loop: Write error at byte offset 587075584, length 4096.

JorgeB Posted October 30, 2020 Share Posted October 30, 2020 There's filesystem corruption on the pool, best bet is to backup, re-format and restore data. P.S: next time please post full diags instead. Quote Link to comment
[email protected] Posted October 30, 2020 Author Share Posted October 30, 2020 I don't see any smart failures in pool. unraid-diagnostics-20201030-1035.zip Quote Link to comment

[email protected] Posted October 31, 2020 Author Share Posted October 31, 2020 (edited) Well backup and rebuilt of the cached pool worked. Pain in the ass. second time i have had to do it. Last time was due to an SSD biting the dust by having a ton of errors. This time, not so sure. Edited October 31, 2020 by [email protected] Quote Link to comment
