patronictl showing no members

Question

I have a 3 node cluster of postgresql running normally using patroni, however when trying to run /usr/bin/patronictl -c /etc/patroni/patroni.yml list

it shows

• Cluster: pg_cluster (uninitialized) ----------+ | Member | Host | Role | State | TL | Lag in MB | +--------+------+------+-------+----+-----------+ +--------+------+------+-------+----+-----------+

although pg_cluster was actually initialized, what could be the reason?

Answer 1

Turned out its due to etcd version patronictl is using. etcd3 needs to be mentioned in case cluster is build using etcd3

patronictl -c /etc/patroni/patroni.yml --dcs-url "etcd3://x.x.x.x:2379" list
