Manager status is NotRunning

Products

• VMware Integrated OpenStack

Issue/Introduction

• Manager status is NotRunning when running viocli get deployment
• The manager FQDN is showing photon-machine.local
• Manager name should be its FQDN.

Environment

7.x

Cause

DNS did not have the FQDN of the VIO Manager at time of firstboot. Forward and reverse lookup need to be working at the time of deployment. The hostname is put into certificates for apiserver and other components during first boot. 

Note: It is not possible to change to a different master node name after deployment.

Resolution

• Backup the VIO deployment.
• Make sure DNS has the correct FQDN of the manager.
• Re-deploy the vApp and the control plane using the proper FQDN of the manager.

Workaround:

1. Remove DNS entry for manager from DNS server
2. hostnamectl set-hostname photon-machine.local
3. systemctl restart kubelet
4. Now master node comes back to normal with photon-machine.local.   Note: This is due to the kubernetes configuration expecting the name.
