BTRFS error on cache drive?

[haley]

Can someone tell me what this could be related to? All of my docker containers quit working. Is it a problem with my cache drive or docker itself?

/dev/sdd1 is a physical drive (probably your cache drive), while /dev/loop2 is the docker.img file so it is not surprising docker is not working.  The diagnostics will provide more information to give you better feedback

Thanks! I was worried this may be a hardware issue. I’ll open it up and see whats going on.
