Tenho um cluster etcd e agora estou tentando inicializar o patroni (no servidor A e no servidor B), mas sempre que tento fazer isso, recebo o erro sobre incompatibilidade de cluster. Tentei remover 'initialize' do etcd, tentei limpar completamente a configuração salva do etcd, mas nenhuma funcionou

Então se eu iniciar o patroni no servidor A, ele inicializará com sucesso, mas se eu executá-lo no servidor B, ele falhará com esse erro. O primeiro que inicializar vence, eu poderia dizer

Patroni no servidor A (B tem o mesmo, mas com posicionamento diferente de endereços):

Como posso consertar isso? Eu já enfrentei esse problema várias vezes naquela época (não consegui consertar)
