我有以下数据库集群：
节点 1：Percona-XtraDB-Cluster-56-5.6.39-26.25.1
节点 2：Percona-XtraDB-Cluster-56-5.6.39-26.25.1
节点 3：Percona-XtraDB-Cluster-56-5.6.41-28.28.1
我按顺序启动节点1、节点2、节点3。集群启动并正常工作。但是现在我的 node1 然后 node2 崩溃了。我的集群（仅限节点 3）继续正常工作。
但我无法启动其他节点（如节点 2）并同步到集群。我曾尝试清除数据库数据目录，然后从头开始同步，但仍然失败。
以下是错误日志：
节点2：服务mysql启动
