Running Unraid 6.9.2
Every other Sunday morning, at precisely 4:30a, I get an error from Fix Common Problems of "Unable to write to Docker Image". This has happened for about 3 months now. At first I thought it was just filling it, so I expanded it. This changed nothing. Spot checking a few times a day for weeks, I have never seen it larger than 15GB or so.
All of the errors have occurred at the same time, with the exception of the one this morning that occurred about 13 min later than I expected. I expect that this is likely related to some sort of scheduled task, but I have been unable to identify anything that runs remotely close to that time on a schedule.
The screenshot is what I see when I view the docker image stats. The containers highlighted in red always run. Most of the others are always stopped. Notice the Writeable column says "nan B".
Also, on the Docker tab, this error is shown dozens of times... "Warning: mkdir(): Input/output error in /usr/local/emhttp/plugins/dynamix.docker.manager/include/DockerClient.php on line 331"
Thanks in advance for your guidance!
