There was an issue upgrading Aria Automation to 8.18.1. When LCM rolled back is appeared that not all the nodes were rolled back leading to a message ErrImagePull error message for some of the pods on two of the nodes when trying to run the deploy.sh script. Running the /opt/scripts/restore_docker_images.sh did not resolve this issue and there was no issue with disks being over allocated.
Aria Automation 8.18.0
The resolution was to restore the snapshots of the nodes taken before the upgrade.
