Description Suresh Kolichala 2020-02-24 22:06:34 UTC

+++ This bug was initially created as a clone of Bug #1806751 +++

Description of problem:

The discover-etcd-initial-cluster tool should archive the data-dir if the target member is unstarted. This is useful for disaster recovery after restoring a backup.

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


How reproducible:
Always

Steps to Reproduce:
1. Bring up a single node cluster by restoring the backup on a single master node using the restore DR script.
2. Force CEO redeployment via oc patch forceredpeloymment=reason-time
3. When CEO redeployment is forced, the existing nodes will start with new pods, a scale up similar to bootstrap will take place
4. Actual results:
The other two nodes stay Unstarted because of the existing /var/lib/etcd/member


Expected results:
The scale up occurs correctly.
