CRITICAL: system ID mismatch, node belongs to a different cluster: 6859654378827691778 != 6859654951670505099

Question

i installed a patroni master node and need to create a pgbackrest replica the master node state is running but the slave node is stopped then it disappear because it looks like it belongs to another database identifier, when i try to run restore command manually pgbackrest --stanza=main --log-level-console=info --delta restore the slave node state change to running

here is the master postgresql.yml file:

and this is the slave postgresql.yml file:

> scope: {{ obasicat }} namespace: /pg_cluster/ name: {{ slave }}
>

>     listen: {{ slave_ip }}:8008
>     connect_address: {{ slave_ip }}:8008

Try update key in etcd/zookeper/consul

7127773868874685913 != 7194568630546240772

/opt/etcd/etcdctl --endpoints=localhost:2379 get /service/stampede/initialize

Getting this key 7127773868874685913

/opt/etcd/etcdctl --endpoints=localhost:2379 put /service/stampede/initialize 7194568630546240772

Updating to new key 7194568630546240772
