正常使用中突然tikv、tiflash自动停止，尝试重启无果，重启机器后，再缩容pd后扩容pd，还是启动超时,tikv、tiflash已经正常启动。
pd 10.10.23.91:2379 failed to start: timed out waiting for port 2379 to be started after 2m0s, please check the log of the instance

提供下以下信息
tidb 版本
pd.log 中是否有信息，目前集群节点存活情况。

pd.log 文件都没有，只有pd_stderr.log 是空的
扩容pd的配置文件 scale-out.yaml
pd_servers:
- host: 10.10.23.91
ssh_port: 22
name: pd
client_port: 2379
peer_port: 2380
deploy_dir: /data/tidb/tidb-deploy/pd-2379
data_dir: /data/tidb-data/pd-2379
log_dir: /data/tidb-data/pd-2379/log
执行 script/run_pd.sh 看下日志情况。

换了log_dir 可以启动，但是日志报错
重启了机器，好了
