[FATAL] [server.rs:428] ["panic_mark_file /data12/tidb/data/tikv-20162/panic_mark_file exists, there must be something wrong with the db. Do not remove the panic_mark_file and force the TiKV node to restart. Please contact TiKV maintainers to investigate the issue. If needed, use scale in and scale out to replace the TiKV node
【附件：截图/日志/监控】
直接通过扩容后再缩容处理吧，最保险处理也很快。
use scale in and scale out to replace the TiKV node
说的是先缩容后扩容，可以试试

第一个出错日志里，提了建议建议通过缩容和扩容替换tikv节点
扩缩容处理吧

port conflict for ‘20162’ between ‘tikv_servers:10.114.26.112.port’
问题出现之前你的部署是怎么样子的？
截个图看看你的机器配置情况？几个 tikv？
之前是好的，7台，昨天有台机器被搞挂了，今天重启不行了，扩容还报端口冲突：“code”: 1, “error”: “port conflict for ‘20162’ between ‘tikv_servers:10.114.26.112.port’ and ‘tikv_servers:10.114.26.112.port’”}

tikv 下线失败 linux/x86_64 Pending Offline
如果在同一台机器上扩容的话，那得换下端口，如果是7台tikv，其中1台panic的话，可以先缩容再扩容试下
先缩容后扩容这个可以试一下，以前遇到过一次就是这么解决的。
我在想出问题的tikv 实例， 在扩容后，能缩容成功吗》
