danev1k1ng Posted April 12, 2018 Share Posted April 12, 2018 Hi, I've started to get some errors lately, and I think it's one of my cache drives that's creating problems. I've got no clue what to look for, so maybe some one here can help me? Attached is the latest diagnostics from the server. Best regards, berta-diagnostics-20180322-1954.zip Quote Link to comment

danev1k1ng Posted April 29, 2018 Author Share Posted April 29, 2018 I finally got some time to look at the problem. I did the sugested things and now the log is floating with "BTRFS csum failed". Anything I can do? berta-diagnostics-20180429-1943.zip Quote Link to comment
JorgeB Posted April 30, 2018 Share Posted April 30, 2018 Run a correcting scrub on the pool and make sure are errors are corrected, if not backup, format and restore. Quote Link to comment
