Docker image might be corrupt, can not stop array, cache disk full and not writable. Please help.


Recommended Posts

Hi! Yesterday I downloaded a large file to my cache drive and when I woke up this morning my cache was full and Docker containers weren't accessible. I thought that was weird since the moved should have been invoked, and also the share holding the large file is set to "use cache drive: yes". I tried removing the large file but unraid didn't notice the change in disk space. I shut down the docker image and got this message.

Warning: stream_socket_client(): unable to connect to unix:///var/run/docker.sock (Connection refused) in /usr/local/emhttp/plugins/dynamix.docker.manager/include/DockerClient.php on line 655
Couldn't create socket: [111] Connection refused
Warning: Invalid argument supplied for foreach() in /usr/local/emhttp/plugins/dynamix.docker.manager/include/DockerClient.php on line 827

Then checking Fix Common Problems i got this error:

Unable to write to cacheDrive mounted read-only or completely full. Begin Investigation

Unable to write to Docker ImageDocker Image either full or corrupted. Investigate 

I then tried to shut down the array, but the disks won't unmount. 

 

I did a diagnostics dump (attached). 

 

Any help would be appreciated!

Thank you!

As the drives did not unmount i force restared the server, now everything is working fine... I do not know what solved the problem and why it occured in the first place. A docker image scrub told me 0 errors. 

The docker file was fine, it was the cache drive’s filesystem requiring a scrub.
