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-foremanconfig:/var/puppet/puppet_rockytrain/controller_rockytrain/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
