Bug 1520467

Build openstack-tripleo-heat-templates-7.0.3-20.el7ost includes a patch from this bug, please update BZ state accordingly

the validation failed with the error: fatal: [192.168.24.21]: FAILED! => {"failed": true, "msg": "The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'rule_name'\n\nThe error appears to have been in '/usr/share/ceph-ansible/roles/ceph-mon/tasks/openstack_config.yml': line 2, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n---\n- name: create openstack pool(s)\n  ^ here\n\nexception type: <class 'ansible.errors.AnsibleUndefinedVariable'>\nexception: 'dict object' has no attribute 'rule_name'"}

with the values of the pools passes by mistral as a JSON:
{u'size': 3, u'pg_num': 64, u'name': u'volumes', u'pgp_num': 64}

and are set in the environment file accordingly: 
    CephPools:
        [{"name":"volumes", "size": 3, "pg_num": 64, "pgp_num": 64}]

Yogev,

I think you have a syntax issue. The CephPools syntax has to match ceph-ansible's rules for defining a pool. I don't recall the full syntax, but I think you need to drop the "pgp_num" part.

Yogev, indeed you can't use pgp_num key. Needs to be retested, moving back ON_QA.

I have followed the official documentation: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/12/html/deploying_an_overcloud_with_containerized_red_hat_ceph/configuring_ceph_storage_cluster_settings#custom-ceph-pools

It stats that pgp_num is valid

Yeah and that's a bug in the documentation, see [1]. We'll need to reverify this without pgp_num :(

1. https://bugzilla.redhat.com/show_bug.cgi?id=1533111

Verified with the configuration: 

    CephPools:
        [{"name": "volumes", "size": 3, "pg_num": 128, "rule_name": ""}]

Please notice that rule_name is not mentioned in documentation
