patroni集群第一次初始化失败，再次使用原来的配置尝试初始化，查看信息，不同节点都显示同一个信息：waiting for leader to bootstrap

原因：
etcd保留了集群的初始化信息（键：/service/$CLUSTER_NAME/initialize）。该键存在后，patroni就不会再次执行initdb。而是尝试再次引导已经存在的节点。
解决方法：
1.使用patronictl手动移除etcd中的/service/$CLUSTER_NAME/initialize
2.设置一个新的cluster name后从新引导
以下是手动移除的过程：
# patronictl -c /opt/app/patroni/etc/postgresql.yml list +---------+--------+--------------+------+---------+----+-----------+ | Cluster | Member | Host | Role | State | TL | Lag in MB | +---------+--------+--------------+------+---------+----+-----------+ | batman | pg01 | 11.11.11.111 | | stopped | | unknown | +---------+--------+--------------+------+---------+----+-----------+ # patronictl -c /opt/app/patroni/etc/postgresql.yml remove batman +---------+--------+--------------+------+---------+----+-----------+ | Cluster | Member | Host | Role | State | TL | Lag in MB | +---------+--------+--------------+------+---------+----+-----------+ | batman | pg01 | 11.11.11.111 | | stopped | | unknown | +---------+--------+--------------+------+---------+----+-----------+ Please confirm the cluster name to remove: batman You are about to remove all information in DCS for batman, please type: "Yes I am aware": Yes I am aware
patroni启动，提示waiting for leader to bootstrap
