办公室有一台二手服务器作为平时开发测试使用。由于机器没放在机房会偶发断电异常断电后文件系统是有出问题的可能的尤其是一些不断在读写合并的文件春节后发现clickhouse启动不了使用systemctl status clickhouse-server返回如下

解决
百度了一堆确实能搜到解决方式牵涉到磁盘挂载、修复之类的试了下没用识别不到磁盘可能是我哪里搞错了暂时舍弃还有一个办法给文件重命名试了下使用mv old_file_name new_file_name重命名直接死机了重启服务器后我使用文件传输工具查看修改文件名竟然成功了。想了下这个损坏的文件应该不能随便移动应该使用rename虽然文件命名成功了但是clickhouse还是无法启动还是类似报错应该是clickhouse还是会使用这个文件想着怎么才能让clickhouse忽略这个文件夹试着把上面层级的文件夹95f改了下改成95f1启动服务后发现可以了
