Docker Service failed to start - Unraid 7.0.1

Featured Replies

Hello,

 

Since upgrading to unraid 7.0.1 I've been having issues with my docker images. After a few days, sometimes even less I get a 'Docker Service failed to start' when going to the docker page. I can still access my dockers through their web ui and they appear to function fine but they are not able to communicate with each other.

 

If I restart the server everything works fine initially but then the same issue reappears. When I do restart or shutdown the server when this error appears, it does fail to successfully stop the array and ends up doing a parity check once it's back up. 

 

I did think it might be my usb drive, I use a USB microSD card reader, I have replaced the memory card with a new one but still have the same problems.

 

This issue has only started since upgrading to 7.0.1, was previous on 6.12, can't remember the exact version.

 

I've attached the system log hopefully that should offer some idea about what it going wrong.

Flash drive issue, you should replace it.

I’ve replaced the microsd card earlier this month and just bought another this week that I’m currently using.

 

I wonder if it’s the sd card reader that might be causing the problem, that’s the only thing that’s stayed the same?

It could be.

I replaced my sd card reader yesterday. Everything seems to be working fine. I’ll give it a week or 2 to see if I get any errors

How has it been since you replaced the reader? I have very similar issues although I don't have an adapter, just a regular USB drive. Exact same symptoms.

I’ve had no issues since replacing the SD card reader

Ok, thanks for the reply. I ran the diagnostics and it appears I'm looking for a new drive as well. Thanks again!
