I've been having an issue recently with this error - This will result in all of my docker containers failing to start or stop.



This is what happens when I try to start a container:

I've tried to expand the size of my docker image which hasn't helped. It's now at 50Gb but it seems the docker image is corrupt, not full.

I stopped the docker service and then deleted the docker image. Then re-imported all my containers. Overnight I get the same error message in the morning.

Does this suggest the disk is failing? It's a 1Tb SSD that is less that a year old 😒 or could it be something else?

The only way to get it working again temporarily is to reboot the server, or stop and start the array, then the docker service.

Here are my diagnostic logs if anyone can take a look:

What are my next steps here? Memtest?

Thanks 😁

Pool filesystem is corrupted; you will need to copy what you can and reformat, but before doing that, I recommend running memtest.

Thanks - I'd already started moving everything from the cache to the array. I've just formatted but used xfs as the file system (I only plan to use one cache drive).

Mover is now moving everything in appdata / domains / system back to the cache drive.

Once that is done I'll do a memtest but hopefully formatting the cache drive will do the trick!
