uaktags Posted March 17, 2019 Share Posted March 17, 2019 So I'm getting this error today and I've checked everything I can possibly think of, and can't for the life of me figure out where it's coming to this conclusion that there's something wrong with my Cache. All 3 drives are reporting healthy in SMART (has nothing really to do with Filesystems, but worth it to know), the drives are mounted, I'm able to copy to/from and edit files that are on the cache, etc. However, I do know something somewhere is wrong because my Docker's are failing randomly with I/O errors. Radarr has been notable: "message": "disk I/O error\ndisk I/O error", Deluge is showing files as downloading though they've done been downloaded already which is weird (manual torrents, so it's not radarr/sonarr related), etc. Alot of weird things that I can only imagine are coming from the cache. Another article i saw with a similar case referenced to go to the wiki on checking filesystems via the webgui. The link itself failed, but I was able to find the relevant wiki and this is what I get: "If the file system is BTRFS, then make sure the array is started, and NOT in Maintenance mode." However the cache page says: " Check is only available when array is Started in Maintenance mode." so I'm at a loss with that. I haven't tried filesystem checks on the other guys yet though because I haven't put the array in maintenance yet. tower-diagnostics-20190317-0006.zip Quote Link to comment
uaktags Posted March 17, 2019 Author Share Posted March 17, 2019 well I'm dense, literally the next paragraph had the explanation for the cache (brtfs) was to use scrub. No errors detected. Quote Link to comment
JorgeB Posted March 17, 2019 Share Posted March 17, 2019 You need to balance the pool to redistribute the data, only one device has free space, and since the pool is raid1 it's the same as being full. Quote Link to comment
