This issue started today after power shutdown. When going into Docker tab I have error Docker Service failed to start.

 

My docker.img file is missing from /mnt/user/system/docker and unraid is unable to create a new one. When I change directory for docker creation it works fine but not inside system directory. In log I see this :

I thought it was problem with cache so I set system directory to not use cache but still same issue.

 

Thank you for your help

Docker image is corrupt, you need to delete and re-create.

 

Next time please post the diagnostics: Tools -> Diagnostics

Thank you for the reply tee-tee jorge, the thing is, unraid is unable to write a new docker.img into the /system/docker location.

Yep, that's why I mentioned posting the complete diags, cache filesystem is also corrupt, you need to backup and recreate cache filesystem, note that checksum errors are usually a sign of bad hardware, like bad RAM.

Hmmm ok great thank you for looking it up for me.
