To set up IPA services for the NFS node in the target cluster, run the following command from the utils/cluster
folder on the control plane:
cd utils/cluster
ansible-playbook install_ipa_client.yml -i inventory -e kerberos_admin_password="" -e ipa_server_hostname="" -e domain_name="" -e ipa_server_ipadress=""
- Hostname requirements
The Hostname should not contain the following characters: , (comma), . (period) or _ (underscore). However, the domain name is allowed commas and periods.
The Hostname cannot start or end with a hyphen (-).
No upper case characters are allowed in the hostname.
The hostname cannot start with a number.
The hostname and the domain name (that is:
hostname00000x.domain.xxx
) cumulatively cannot exceed 64 characters. For example, if thenode_name
provided ininput/provision_config.yml
is ‘node’, and thedomain_name
provided is ‘omnia.test’, Omnia will set the hostname of a target compute node to ‘node00001.omnia.test’. Omnia appends 6 digits to the hostname to individually name each target node.
Note
Use the format specified under NFS inventory in the Sample Files for inventory.
