plz tell me the new etcd cluster make using etcd snapshot.

[kimjinju730]

Hello,
I've been thinking about it for a few days now, trying it out, and I'm really confused, so I'm going to ask a question.

etcd cluster
etcd1 / etcd2 / etcd3

However, as the etcd1 and etcd2 servers died, it became less than quorum.
But I can't use the etcd1 and etcd2 servers right away.

We need to rebuild the etcd cluster from the creating snapshots by adding new servers named etcd4 and etcd5.
Is this the right way to do it?
🙏

Hey @kimjinju730 - Please refer to our cluster recovery guide here in the first instance: https://etcd.io/docs/v3.5/op-guide/recovery/#restoring-a-cluster

Hey, @jmhbnz
I know that the link you mentioned is only possible if the initial initial-cluster member is the same.

What I want is a way to restore the snapshot data to another initial-cluster member with the existing snapshot information. Please let me know if you know.

Here is simple step test senario.

1. etcd cluster member (�initial cluster member)

• ETCD_INITIAL_CLUSTER=patroni-etcd-test1=http://1.1.1.1:2380, patroni-etcd-test2=http://2.2.2.2:2380, patroni-etcd-test3=http://3.3.3.3:2380

2. etcd quroum failed -> only patroni-etcd-test1=http://1.1.1.1:2380 remain server (patroni-etcd-test2/patroni-etcd-test3 server dead)

3. I want to add the patroni-etcd-test4 server to restore the data to the old snapshot file.

My etcd version v 3.4.18
