Hi everyone, We have the Kolla Openstack site, which is 3 HCI (Controller+Compute) + 3 Storage (Ceph OSD) site without internet. We did the shutdown few days ago since CNY holidays. Today we re-launch whole cluster back. First we met the issue that MariaDB containers keep restarting, and we fixed by using mariadb_recovery command. After that we check the status of each services, and found that all services shown at Admin > System > System Information are DOWN. Strange is no MariaDB, AMQP connection, or other error found when check the downed service log. We tried reboot each servers but the situation still a same. Then we found the RabbitMQ log not updating, the last log still stayed at the date we shutdown. Logged in to RabbitMQ container and type "rabbitmqctl status" shows connection refused, and tried access its web manager from <VIP>:15672 on browser just gave us "503 Service unavailable" message. Also no port 5672 listening. I searched this issue on the internet but only few information about this. One of solution is delete some files in mnesia folder, another is remove rabbitmq container and its volume then re-deploy. But both are not sure. Does anyone know how to solve it? Many thanks, Eddie.
