I may be wrong in my simulation (my first time), but in that case you will have to describe how did you setup your cluster, did you use any reference etc?maybe that might help me understand this more.
just following up on this, I was new to etcd and installed v3.5.x and was not sure how to list all keys etc,
turns out, I had to set ETCDCTL_API=2, and use the old version commands to list and del key.
export ETCDCTL_API=2 # ls does not work on v3
alias ee='etcdctl --endpoints=http://127.0.0.1:2379 '
# i used default namespace and cluster name, so
postgres@db:~/patroni_demo$ ee ls --recursive /
/service
/service/batman
/service/batman/members
/service/batman/members/postgresql0
/service/batman/members/postgresql1
/service/batman/initialize --- this is the key we need to delete to reinit the db
/service/batman/config
/service/batman/leader
/service/batman/optime
/service/batman/optime/leader
postgres@db:~/patroni_demo$ ee get /service/batman/initialize
6981912157875070537
# solve i am not leader, server not starting up
ee rm /service/batman/initialize
PrevNode.Value: 6981912157875070537
and then run patroni <config> again as a fresh setup, and you get your leaders and replica just fine.
