johmei Posted February 19, 2022 Share Posted February 19, 2022 When you set something up so long ago...you really forget so many things 😕 I'm not exactly sure what information is needed, but I'll start with the Diag File. In my Dashboard, one of my cache drives in the pool is stating it has an error. I guess that has something to do with the issue but I thought the point of having a mirrored cache drives was that when one breaks, the other continues to function but that doesn't seem to be the case. I need to take care of this and I'm worried about losing data that is still on the cache that hasn't been moved yet. The cache is just acting weird and I'm worried about losing data, otherwise, I'd just be reading the manual and messing with stuff myself. Please advise and/or ask follow up questions as I know I left important information out.  Samsung_SSD_850_EVO_500GB_S21HNXAG941287N is the first cache drive and Samsung_SSD_850_EVO_500GB_S21HNXAG643841J is the second cache drive (the one with the errors)  Thanks so much johnsnas-diagnostics-20220219-0422.zip Quote Link to comment
Solution JorgeB Posted February 19, 2022 Solution Share Posted February 19, 2022 Cache2 is showing some SMART issues but should be fine for now, you can run an extended SMART test to confirm, main problem is that the pool is completely full, you need to move/delete some data from there, avoid completely filling up any COW filesystem, like btrfs or zfs.

That's the weird thing though....I have the mover scheduled for every week and I know I don't load up 500 GB or even close in a week. This has never happened before and I tried to manually invoke the mover and nothing. And when I try to view the pool....there's no data on there other than about 10-20 GB worth for my Docker Plugins and that includes a 10 GB for the docker image, at least not that I can see. I have no idea how it is saying there is no space on it. It makes no sense. It's never gotten even remotely close to filling up since I first fired this system up about 6 or 7 years ago. Any thoughts?
