[SOLVED] Docker - read-only file system

[zyke]

As the topic reads, was trying to install a new docker app, and recieved an error with "read-only file system". When checking the logs, I could see similar issues where the current dockers are unable to write logs

 

time="2021-03-04T11:53:11.079134440+01:00" level=error msg="Failed to log msg \"\" for logger json-file: write /var/lib/docker/containers/4312a9b16e3a529e33ebc383c2a8b41800d7ffaa72f3b91b9fb609f7a172d569/4312a9b16e3a529e33ebc383c2a8b41800d7ffaa72f3b91b9fb609f7a172d569-json.log: read-only file system"

 

There does not seem to be any issues with creating files or folders on the cache drive itself, so I assume that the docker img have become correpted. Attached is the diagnostics.

 

If someone could please help me out here, and also please tell me where you find things so I can get a greater understanding of how to TS unraid. 

 

If it is the docker img that is corrupted, is there a process on how to replace the docker img file and keep the settings, since the config files are in the /appdata/* I assume it should just be to remove the old docker image, get a new and reinstall the apps?

 

Thanks in advance!

Thank you for this! I followed the steps outlined, it worked like a charm. Recreated the dockers with going to "Docker" then "Add Container" and just added one of the ones I had used before and everything worked like a charm!
