Description Alex Stupnikov 2023-07-31 14:26:34 UTC 
Description of problem:

In RHOSP 10->13 upgrade document we had a section explaining steps to verify extra config defined using SECTION/parameter syntax to avoid common problems during FFU procedure when some parameter was added to puppets. https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/13/html-single/fast_forward_upgrades/index#checking-parameters-in-custom-hieradata

Skipping this steps will block FFU procedure with similar error:

<13>Jul 26 10:45:10 puppet-user: Error: Evaluation Error: Error while evaluating a Function Call, Duplicate declaration: Keystone_config[identity/password_hash_algorithm] is already declared at (file: /etc/puppet/modules/keystone/manifests/init.pp, line: 850); cannot redeclare (file: /etc/puppet/modules/keystone/manifests/config.pp, line: 31) (file: /etc/puppet/modules/keystone/manifests/config.pp, line: 31, column: 3) on node somenode.example.com

This section is no longer there for RHOSP 16.2, while it is still a must: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16.2/html-single/framework_for_upgrades_13_to_16.2/index
