Role documentation

compute-tsx

RHEL8.x kernel flag for Compute nodes validation.

RHEL-8.3 kernel disabled the Intel TSX (Transactional Synchronization Extensions) feature by default as a preemptive security measure, but it breaks live migration from RHEL-7.9 (or even RHEL-8.1 or RHEL-8.2) to RHEL-8.3.

Operators are expected to explicitly define the TSX flag in their KernelArgs for the compute role to prevent live-migration issues during the upgrade process.

This also impacts upstream CentOS systems.

deprecated-services

Check if roles data doesn’t include deprecated services.

Validate that the custom roles_data.yaml provided in the upgrade prepare step doesn’t have any deprecated services. This has been an issue among customers for a long time, which has been addressed by documentation. However, we should have some way to alert the user that the roles_data they provide has deprecated services before starting the upgrade procedure and getting an ugly error.

Role documentation

nova-status

Nova Status Upgrade Check.

Performs a release-specific readiness check before restarting services with new code. This command expects to have complete configuration and access to databases and services within a cell. For example, this check may query the Nova API database and one or more cell databases. It may also make requests to other services such as the Placement REST API via the Keystone service catalog

The nova-status upgrade check command has three standard return codes:

0 -> All upgrade readiness checks passed successfully and there is nothing to do. 1 -> At least one check encountered an issue and requires further investigation. This is considered a warning but the upgrade may be OK. 2 -> There was an upgrade status check failure that needs to be investigated. This should be considered something that stops an upgrade.

  • hosts: nova_api

  • groups: backup-and-restore, pre-upgrade

  • parameters:

  • roles: nova_status

Role documentation

undercloud-ipa-server-check

Verify that the IPA server has the right permissions and ACI.

This validation is relevant for systems where TLS Everywhere is enabled.

A new ACI is needed on the FreeIPA server to ensure that certificates with IP SANs can be issued. This ACI will be delivered by default from FreeIPA 4.8.5.

In addition, a new permission is needed to add DNS zones for tripleo-ipa. This permission is an addition to the current permissions for the Nova Host Manager role.

This validation confirms that the new permission and ACI are present.

Role documentation

validate-passwords-file

Check Undercloud passwords file.

Disallow updates if the passwords file is missing. If the undercloud was already deployed, the passwords file needs to be present so passwords that can’t be changed are persisted. If the file is missing it will break the undercloud, so we should fail-fast and let the user know about the problem. Both the old and new path to the file is checked. If either is found, the validation will pass as the old path will be migrated to the new during and update/upgrade.

  • groups: prep, pre-upgrade, pre-update

  • parameters:

  • roles: validate_passwords_file
