Comment 4 Sahina Bose 2018-10-29 07:28:31 UTC

The replace node needs to be tested w.r.t RHHI. Sas/Bipin, do we need a corresponding RHHI bug to track this?

Comment 16 Amrita 2020-05-19 11:22:14 UTC

As confirmed with Prajith, approved doc text is 

Previously, a corrupted {Gluster} peer node was manually reconfigured and was added back to the {Gluster} cluster. In this release, replacing a {Gluster} peer node in a {Gluster} cluster , helps reconfigure {Gluster} and adds the reconfigured node back to the cluster.

Comment 17 SATHEESARAN 2020-05-27 04:45:43 UTC

Tested with gluster-ansible-maintenance-1.0.1-2.el8rhgs

When running the playbook, the gluster peer membership is restored correctly,
but the volume restoration is not complete. And for that particular issue,
there is a separate bug tracked - https://bugzilla.redhat.com/show_bug.cgi?id=1840003

Upstream PR: https://github.com/gluster/gluster-ansible/pull/108

Comment 20 SATHEESARAN 2020-06-11 18:40:25 UTC

Tested with gluster-ansible-maintenance-1.0.1-4.el8rhgs and gluster-ansible-roles-1.0.5-12.el8rhgs and RHVH 4.4.1

1. All the playbooks and inventories required for node replacement are available
2. Successfully replace the node with the same host post reinstallation with the same FQDN
