Description SATHEESARAN 2020-05-26 12:07:34 UTC

Description of problem:
------------------------
Its highly possible one of the hosts in the RHHI-V cluster may go non-operational, and in those cases users prefer to reprovision the same host fresh post fixing the problems and restore the hosts.

This is achieved by the replacing the faulty-previously-existing-node by renewed-itself.

This procedure should be available as a playbook, so that the user could perform it with ease


Version-Release number of selected component (if applicable):
-------------------------------------------------------------
RHHI-V 1.8

How reproducible:
-----------------
Not applicable


Actual results:
------------------
No easy method to do this process of replacing the host by itself

Expected results:
-----------------
Easy playbook that replaces the host by itself.

Comment 1 SATHEESARAN 2020-06-03 09:58:41 UTC

Dependent bug is already ON_QA

Comment 2 SATHEESARAN 2020-06-08 10:39:43 UTC

Tested with RHV 4.4.1 and gluster-ansible-maintenance-1.0.3.el8rhgs

There are 2 failures

1. Syntax error related to unremoved "-block" in the role
2. Semantic error, where the 'gluster_ansible_cluster_node' is used to replace host workflow

Comment 3 SATHEESARAN 2020-06-15 09:24:02 UTC

Tested with gluster-ansible-roles-1.0.5-12.el8rhgs

The ansible roles for replacing the host with the host of the same name/FQDN post reprovisioning,
is available

[root@ ~ ]# ls /etc/ansible/roles/gluster.ansible/playbooks/hc-ansible-deployment/ | grep node
node_prep_inventory.yml
node_replace_inventory.yml
[root@ ~ ]# ls /etc/ansible/roles/gluster.ansible/playbooks/hc-ansible-deployment/tasks/ | grep node
replace_node.yml
