Hi all

I was having some issues with docker images failing to pull. So I rebooted my unRAID machine to see if that would fix things and now the docker service failed to start and loop2 is in read-only mode. I have done nothing after tuning the machine back on and seeing the error. Any help would be much appreciated, don't want to lose any data! Syslog attached.

Cache is completly full, free up some space.

Perfect, thank you! Looking at it now, that was bloody obvious!

Ok, still isn't quite fixed. I can start up fine. Managed to remove some unused containers so docker service starts now. 30GB free on cache disk, but I still can't pull an image. Puts the cache disk into read only.

Due to cache running out of space the docker image got corrupted, but it's easy to re-create.
