Description Lukas Svaty 2018-01-30 16:03:26 UTC
Description of problem:
if config.yaml of ovirt-metrics is present on host deployment gluster playbooks are being run. I suspect we are changing types of hosts facts from bool to str, thus when condition on gluster roles passes as true with string "false"

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Set up metrics (config.yml)
2. Create cluster with Gluster service disabled
3. Add host to this cluster

Actual results:
Host deployment fails becuase of missing repositories for gluster on hosts. Host gluster ansible playbooks are being triggered.

Expected results:
Metrics should not affect host facts for other playbooks.

Additional info:
this can be checked in ovirt-engine/playbooks/ovirt-host-deploy.yml
when: host_deploy_virt_enabled and host_deploy_gluster_enabled

while retyping the variable to bool works

when: host_deploy_virt_enabled |bool and host_deploy_gluster_enabled | bool passes the var correctly

This is a dirty fix though and we need to ensure oVirt-metrics playbooks are not modifying type of host facts.

Please attach the ovirt-host-deploy-ansible log file.

Comment 2 Lukas Svaty 2018-02-28 11:20:51 UTC
Shirly can you please specify what are you looking for in deploy log? I believe there is no additional information there. I would recommend trying to reproduce this.

Running deployment playbook:
2018-02-28 12:10:53,251+01 INFO  [org.ovirt.engine.core.common.utils.ansible.AnsibleExecutor] (EE-ManagedThreadFactory-engine-Thread-14) [1ba50bd6] Executing Ansible command:  [/usr/bin/ansible-playbook, -v, --private-key=/etc/pki/ovirt-engine/keys/engine_id_rsa, --inventory=/tmp/ansible-inventory2784335582542152903, --extra-vars=host_deploy_cluster_version=4.1, --extra-vars=host_deploy_cluster_name=CL41, --extra-vars=host_deploy_gluster_enabled=false, --extra-vars=host_deploy_virt_enabled=true, --extra-vars=host_deploy_vdsm_port=54321, --extra-vars=host_deploy_override_firewall=true, --extra-vars=host_deploy_firewall_type=IPTABLES, --extra-vars=ansible_port=22, --extra-vars=host_deploy_post_tasks=/etc/ovirt-engine/ansible/ovirt-host-deploy-post-tasks.yml, --extra-vars=host_deploy_ovn_tunneling_interface=, --extra-vars=host_deploy_ovn_central=null, /usr/share/ovirt-engine/playbooks/ovirt-host-deploy.yml] [Logfile: /var/log/ovirt-engine/host-deploy/ovirt-host-deploy-ansible-20180228121053-]

See... vars=host_deploy_gluster_enabled=false
However gluster playbooks are being run

Looking into /usr/share/ovirt-engine/playbooks/ovirt-host-deploy.yml:
- hosts: all
  remote_user: root

    - role: ovirt-host-deploy
    - role: hc-gluster-cgroups
      when: host_deploy_virt_enabled and host_deploy_gluster_enabled
                                          ^^ This should be False
... output omitted...

However, if metrics playbook were running on the host it's "False" instead of False.. thus string "False" in condition is True

Inside host deploy log you will see only deployment playbook, metrics playbook and afterwards gluster playbook, nothing unusual.
