September 24, 20205 yr Community Expert There's filesystem corruption in the pool, best bet it to backup and re-format the pool.

So I just finished performing those steps and got this error for docker: Your existing Docker image file needs to be recreated due to an issue from an earlier beta of Unraid 6. Failure to do so may result in your docker image suffering corruption at a later time. Please do this NOW!
