My unraid box has worked fine for a while, but a couple of days ago we had a power cut. AFter strting up agin the core aray is fine, but any Docker containers I start up are causing the whole array to become unresponsive.

 

The culprit always seems to be BTRFS errors, though even if I delete the docker.img file they always come back. Ive done a full party check, and dont see any errors, so why would a standalone img file have internal file-system errors?

Since no one else has jumped to give you some assistance, I thought I might make a couple of suggestions.

 

First, have you seen and read this article on checkinig files systems:

Second, most of the Gurus usually want to see the diagnostic file.  I would suggest that you attach it to your next post.
