Server suddenly restarted without notice, then Docker Service failed to start

[PzrrL]

Hello there, my server restarted unexpected around 9 hours ago, and I just realised that. The server is now checking the parity. However, when I try to access the Docker tab, it says "Docker Service failed to start". and I am not able to restart the docker service. I see buch of "kernel: md: disk5 read error, sector=3530271264" logs from the recent log.

 

Attached please also find my diagnostics, pleas kindly help thanks 🙏

Disk5 appears to be failing, run an extended SMART test, regarding docker, the image is corrupt, delete and recreate:

 

https://docs.unraid.net/unraid-os/manual/docker-management/#re-create-the-docker-image-file
Then:
https://docs.unraid.net/unraid-os/manual/docker-management/#re-installing-docker-applications
Also see below if you have any custom docker networks:

Thanks for your prompt response and insight!

I will run an extended SMART test for disk 5, and also recreate the docker image, thanks for the guide.

 

However, is there any clues on why the server suddenly restarted unexpected? I have been randomly experiencing this a few times in this year. 😕

Usually it's bad power or some failing hardware.

Thanks. Regarding re-installing dockers applications, since I have installed the FolderView, is there any chance I can re-create the layout that I used to use? Also find some clues on what applications did I use. I do have appdata backup.

Besides, I did not remember which repo's images that I used at the end (as I tried out multiple images of the same applications). Is there anyway to find them out? Thanks

I don't know, never used that, suggest asking in the plugin support thread.

Issues resolved for the layout. Thanks. Just a suggestion to add a log/config/record of the list of dockers' template used. Then it can be backed up together with the CA backup. This will reduce more pain on re-creating all the dockers. 🙏 thanks a lot for all the info
