I think I have a failing drive in my cache pool

This evening some of my docker containers have stopped running and cannot be started or updated. I cannot write to my cache share any my syslog is full of errors similar to the below:

I have attached diagnostics. Is one of my cache drives failing and if so, how do I know which one? Also, what is the replacement procedure?

Actually nevermind. I can write to my cache share just fine. A little more searching on my part led med to this guide on removing my docker image file and recreating it which seems to have solved the issue.
