trurl Posted September 14, 2020 Share Posted September 14, 2020 Looks like you have corrupt docker.img. Delete and recreate Also, appdata has some files on the array. Is this intentional? Having them on the array may impact performance and keep disks spunup. Quote Link to comment

JorgeB Posted September 15, 2020 Share Posted September 15, 2020 Cache filesystem is corrupt, you need to backup and reformat, then recreate docker image. Quote Link to comment
hilljiffy Posted September 15, 2020 Author Share Posted September 15, 2020 cheers mate i have done that and its all working again.this is the 3rd time this has happened.any ideas why it would do this. Quote Link to comment
JorgeB Posted September 16, 2020 Share Posted September 16, 2020 If cache keeps getting corrupt without an apparent reason that usually indicates a hardware problem. Quote Link to comment
