MEF Center Runs Abnormally Due to the Node-Pressure Eviction Mechanism

Symptom

If resources such as memory, drives, and PIDs are insufficient when Kubernetes deploys and runs MEF Center, node-pressure eviction is triggered. As a result, MEF Center services cannot run properly.

Cause Analysis

MEF Center images are evicted due to node-pressure eviction.

Solution

1. Clear the drive space to ensure that the storage space is sufficient and the remaining drive space of /var/lib/docker is greater than or equal to 10%.
2. Uninstall MEF Center, and reinstall it and restart its services.
   • If MEF Center fails to be uninstalled, try to uninstall it again.
   • If MEF Center fails to be restarted, run the docker images command to view the image that is evicted. Then, go to the corresponding image path /MEF-Center/mef-center/images/module name/image under the MEF Center installation path, and run the docker load -i image_name command to restart MEF Center.
