mv /etc/yum.repos.d/advanced-virtualization.repo /etc/yum.repos.d/advanced-virtualization.repo.old
yum install centos-release-advanced-virtualization.rpm

...

and then rerun puppet

• Disable the compute node so that it doesn't accept new VMs:

  Code Block
  language bash
  openstack compute service set --disable cld-np-19.cloud.pd.infn.it nova-compute

  
  

• Start and enablepuppet:

  Code Block
  language bash
  systemctl start puppet; systemctl enable puppet

  
  

• Enable the checks in Nagios for this host

• Wait till all checks are ok (in particular the VM network and volume one)

• Add this node in the following scripts on cld-ctrl-01: /usr/local/bin/display_usage_of_hypervisors.sh, /usr/local/bin/host_aggregate.sh, /usr/local/bin/new_project.sh, /usr/local/bin/free_resources_compute_nodes.sh
• Add this node in the /etc/cron.daily/vm-log.sh script on cld-log
• Create the directory /var/disk-iscsi/qemu/cld-np-19 in cld-log
• Verify that a ssh from root@cld-log to root@cld-np-19 works without requiring password

• Stop puppet on the 2 controller nodes:

  Code Block
  language bash
  systemctl stop puppet

  
  

• Add the new compute node in cld-foreman:/var/puppet/puppet_rocky/controller_rocky/templates/aai_settings.py.erb

• Run puppet on the first controller node (this will trigger a restart of httpd):

  Code Block
  language bash
  puppet agent -t

  
  

• Run puppet on the second controller node (this will trigger a restart of httpd):

  Code Block
  language bash
  puppet agent -t

  
  

• Start puppet on the two controller nodes:

  Code Block
  language bash
  systemctl start puppet

  
  

• Enable the host:

  Code Block
  language bash
  openstack compute service set --enable cld-np-19.cloud.pd.infn.it nova-compute

  
  

• Run the aggregate_manage.sh script to add the node in the relevant hostgroups, e.g.:

  Code Block
  language bash
  /usr/local/bin/aggregate_manage.sh add cld-np-19.cloud.pd.infn.it INFN
