SOLVED: Dockers fail to start with 7.3.1

Featured Replies

I updated from 7.2.4 to 7.3.1 yesterday. The update process seemed to go fine, but upon restart it reported errors on my second cache pool drive (which is made of 2 NVMe drives on a Supermicro riser card installed on a Supermicro X12SPi-TF motherboard) that had not been reported previously on 7.2.4.

None of the Docker modules in the Arr stack (Prowlarr, Sonarr, Radarr) would start and gave an Execution Error - Bad Parameter. They were also listed as having invalid IP addresses.

Diagnostics are attached.

Any help appreciated. I have successfully reverted to 7.2.4 (I had the same problem with 7.2.7) but obviously cannot stay on that version forever.

Many Thanks.

Let's start with the pool, one of the devices reporting corruption errors, also the docker image, start by scrubbing the pool and post the result from the GUI.

I had this same problem when I first updated to 7.3. It was caused by me using --net=container:<vpn container name> in extra parameters to route containers through another container. This no longer appears to work in 7.3+ (at least not for me). I had to remove this extra parameter and instead set Network Type to Container and below that set Container Network to the VPN docker that I want it to route through.

@wgstarks Thank you! Editing the docker settings by setting "Network Type" to "Container" and then setting "Container Network" the "binhex-deluge-vpn" solved this problem! All Dockers are now working normally again.

I ran scub twice once under 7.2.4 and a second time under 7.3.1. The results appear the same.

I also ran an extended SMART self-test on the NVMe drive that was reporting errors; that report is attached.

Thank you @JorgeB for your help with this.

Since no errors were found, clear the stats for the pool and keep monitoring, they are likely old errors.

  • Author

@JorgeB I will clear the pool state then.

You mentioned a docker image problem, too. Are there additional steps I need to take with respect to that?

Thank you.

If the containers are working fine it should be OK, but you can also recreate the Docker image to correct that.
