btrfs is detecting data corruption on both pools devices, start by running memtest, then scrub the pool and post the result from the GUI.

Hello JorgeB, thanks for the reply

I have run memtestand and ended up without errors.

Even so, I switched my RAMs from 2 sticks of 16gb for 2 new sticks of 8gb.

I even switched both my cache sata SSD drives for 2 new NVMe drives and started a fresh new cache pool.

Containers still wont start and keep getting the same errors.

When I go to the docker settings to do the scrub, it crashes immediatly and status says aborted:

Scrubbing the cache pool, also dont get any errors:

The weird thing is, since the beggining, some containers work, but most dont:

All those who are stopped, give "server error" or "error 403"

Could it be the docker image corrupted?

I wish I didnt have to format and reinstall all over again...

If there is anything i could do to give more information, feel free to ask.

Thanks in advance.

If no errors were found, try recreating the docker image:

https://docs.unraid.net/unraid-os/troubleshooting/common-issues/docker-troubleshooting/#re-creating-the-docker-image-file

Then:

https://docs.unraid.net/unraid-os/troubleshooting/common-issues/docker-troubleshooting/#reinstalling-docker-applications

Also see below if you have any custom docker networks:

https://docs.unraid.net/unraid-os/troubleshooting/common-issues/docker-troubleshooting/#restoring-docker-custom-networks

Thanks JorgeB, I followed your guide instructions, I disabled Docker, clicked the 'delete vDisk' checkbox and Delete button), and then proceeded to re-enable Docker.

Than started reinstalling the docker containers again. I installed most, only the important ones and so far so good.

All containers are working again,

Seems All are working fine, but for some reason the only one I cant get acess to the WebUI is Plex.

Everytime I try to open WebUI I get this:

Plex logs are showing crash errors. Is there any log or diagnostic i can download and post here. cause idont know how to save this plex log.

Also, If this has something to do with the costum docker networks, I might have fucked up in that last part cause I've deleted the vDisk file before checking the names of my previous costum networs.

And now I cant remember wich I had before. Is there anyother way to recover them?

I'm afraid that I can't help with that since I've never used it. I recommend looking for it's support thread, or someone else may be able to help.

Not that I know of.

I was able to copy the error and done a little bit of research. Finally figured out what was the problem with Plex.

Seems the database files were also corrupted, so I had to delete the old files and force plex to recreate new ones.

For someone else who might face the same problem, the files are in Appdata/Plex/Library/Application Support/Plex Media Server/Plug-in Support/Databases

Just delete the files on that folder, or restore from an old backup.

In the end, with good guidance, some research and hard work, my Unraid is flowing again.

Thank you so much JorgeB for all the help, you rock! 💪
