Unraid 6.9.2

[AGuyInTheWrongRoom]

Hi everyone,

 

I don't know where else to ask and seeing as I'm quite new to this I'm completely lost:

 

I recently updated to Unraid 6.9.2. After completing the updated, I kept working on the server for a few more minutes and after that decided to restart the array for the changes to take effect.

 

After restarting I had this problem - Docker Service Failed to Start. I have no idea why and I don't know what the contents of the log mean.

 

Did a parity check and everything looks good.

 

I ran and downloaded the diagnostics, and the docker log file reads as follows:

 

time="2021-10-13T19:16:01.590161186-07:00" level=error msg="garbage collection failed" error="input/output error"

Could someone give me a hand and tell me what I have to do to get the Docker Service running again?

Post your diagnostics

Hi,

 

@Squid, I'm sorry, I thought the log was what would be needed. After your message I tried posting it but I had a 1 post/day limit. Since then I haven't managed to come to the forum.

 

The server has actually been functioning on and off this last week and a half. After my initial post, it somehow "fixed" itself temporarily and the Docker Service started working again without me doing anything, then broke down a couple more times and came back on.

 

Right now the Docker Service can't be started. This is the diagnostics I ran a few minutes ago.

 

I also had this error message in the docker tab:

 

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 682

Start with recreating the docker.img file https://forums.unraid.net/topic/57181-docker-faq/?tab=comments#comment-564309

OK I did that now. The docker image path was "/mnt/user/system/docker/docker.img" so after deleting it I moved the path to "mnt/cache/docker.img" as you suggested.

 

I reactivated the Docker service and rebooted the system, but still nothing. I noticed that the cache disk was full. I only have one cache disk which is a 120GB SSD, and it's being used to save incomplete torrent downloads. Now that I think about it, it has been full or close to full almost always.

 

So I after recreating the docker image and rebooting the system without results, I ran the mover which cleared space on the cache disk and then rebooted the system. This time it worked and the docker service was enabled. I'm now redownloading my applications.

 

So I guess that's it, it's solved? Thank you for the help.

 

I guess I still have some reading to do regarding the use of the cache and how to keep it from being used at full capacity.
