37 Troubleshooting the ESX

This section contains troubleshooting tasks for your SUSE® OpenStack Cloud 9 for ESX.

37.1 Issue: ardana-service.service is not running

If you perform any maintenance work or reboot the Cloud Lifecycle Manager/deployer node, make sure to restart the Cloud Lifecycle Manager API service for standalone deployer node and shared Cloud Lifecycle Manager/controller node based on your environment.

For standalone deployer node, execute ardana-start.yml playbook to restart the Cloud Lifecycle Manager API service on the deployer node after a reboot.

For shared deployer/controller node, execute ardana-start.yml playbook on all the controllers to restart Cloud Lifecycle Manager API service.

For example:

cd ~/scratch/ansible/next/ardana/ansible
ansible-playbook -i hosts/verb_hosts ardana-start.yml --limit HOST_NAME

Replace HOST_NAME with the host name of the Cloud Lifecycle Manager node or the Cloud Lifecycle Manager Node/Shared Controller.

37.2 Issue: ESX Cluster shows UNKNOWN in Operations Console

In the Operations Console Alarms dashboard, if all the alarms for ESX cluster are showing UNKNOWN then restart the openstack-monasca-agent running in ESX compute proxy.

  1. SSH to the respective compute proxy. You can find the hostname of the proxy from the dimensions list shown against the respective alarm.

  2. Restart the openstack-monasca-agent service.

    sudo systemctl restart openstack-monasca-agent

37.3 Issue: Unable to view the VM console in Horizon UI

Procedure to enable gdbserver

  3. On the left hand side select Security Profile from the list of Software. Click Properties on the right hand side.


    Firewall Properties box displays.

  4. Select gdbserver checkbox and click OK.
