I’ve been experiencing an issue with Docker crashing on my HassOS system, and it’s been quite a puzzle to solve. The system goes into an endless reboot loop, which is frustrating, especially since it’s a production environment. Let me share what I’ve discovered and how I’m working towards a resolution.
The problem started after a sudden power loss. Upon reboot, Docker fails to start, leading to a cycle of restarts. The logs show errors related to failed goroutines and warnings about missing modules like aufs. I’ve also noticed messages indicating that Docker couldn’t spawn more processes, which is puzzling since our system limits are set appropriately.
I’ve tried several troubleshooting steps:
- Inspecting Logs: The systemd logs revealed stack traces and warnings about missing modules. The
Resource temporarily unavailableerror suggests Docker might be hitting process limits, but I’m not entirely sure how that’s happening. - Clearing Containers: I attempted to remove all containers and images, hoping to reset Docker’s state. This didn’t resolve the issue.
- Checking System Resources: I reviewed CPU and memory usage, but everything seems within acceptable limits.
One potential lead is the aufs module warning. I’m researching whether this could be contributing to Docker’s instability. If aufs is indeed the culprit, I might need to switch to a different storage driver, though I’m not sure how feasible that is in HassOS.
Another angle is the process limit issue. I’m looking into adjusting Docker’s settings to handle more processes, but I’m cautious about making changes that could destabilize the system further.
I’m also considering whether a corrupted Docker database might be the root cause. Resetting it could be an option, but I’m hesitant without a clear backup strategy.
The community has been helpful, but most solutions I’ve found are workarounds like reflashing the SD card, which isn’t practical for my setup. I’m hoping to find a more permanent fix that doesn’t involve disrupting user data.
If anyone has encountered similar issues or has insights into Docker’s process management or storage drivers, I’d greatly appreciate your input. Let’s work together to resolve this!
