Current helm values:

release:
  version: "4.0.1"
mayastor:
  enabled: true
  etcd:
    replicaCount: 3

Previous helm values:

release:
  version: "4.0.1"
mayastor:
  enabled: true
  etcd:
    replicaCount: 1

To Reproduce

  • install openebs helm with mayastor etcd replica 1
  • upgrade chart with etcd replica 3

Expected behavior
all etcd members are healthy

I don't think this will work automatically.
Can you provide some points @datacore-tilangovan ?

did also a test scalling to 2 replicas, in that case etcd-0 was healthy but etcd-1 show errors:

Also after 1st case when I rollback from 3 to 1 replica for etcd. etcd-0 lost its all data. Fortunately I made a snapshot of etcd before and restored it.

In 2nd case when scalling from 1 to 2 and rollback from 2 to 1. etcd-0 was healthy entire time so data was kept.

I haven't had the time yet, but I wonder if the etcd-operator would help here? #1630
