User data doesn't seem to be stored here, job data is stored here.

After I reset and installed the cluster, the job data still existed, but the user data was gone, including username, password, e-mail, SSH public Keys et. al.

I see that user information and group information are stored in the Secret, so now the problem seems to be how to backup and restore the Secret of k8s.

You are right, if you delete the data file fot etcd, then user/group info will be lost. We need to dump secrets first then apply them to the new cluster

So running the following command will reset the cluster, but all etcd data will be lost, please be careful.

ansible-playbook -i inventory/pai/hosts.yml -e "ansible_python_interpreter=/usr/bin/python3" reset.yml --become --become-user=root -e "@inventory/pai/openpai.yml"
