May 24, 20206 yr The last couple days I have been having issues with docker stopping at exactly the same time every morning and then not coming back up. I looked at the logs and realized that was when CA Backup does a backup of my appdata folder and then I see the error that /mnt/cache/docker.img is in-use, cannot mount. I then spend the next 30 minutes trying to get docker to start again, which includes some restarts of the machine, stopping and starting Docker until it just finally starts up. I have disabled these auto backups for now to hopefully alleviate the issue temporarily, but I am just curious to know why this all of a sudden started happening and wondering if anyone has any ideas. I have been doing these backups for at least the last year no issues and it does not look like anything has been updated in the last couple days to change behavior.
May 24, 20206 yr Author I had rebooted the server prior to pulling these diags. It looks like the logs start then and it did start docker, so it looks like the logs don't show the time of the incident. unraidserver-diagnostics-20200524-0801.zip
