Error: failed to start tiflash: failed to start: 182.92.101.109 tiflash-9000.service, please check the instance's log(/tidb-deploy/tiflash-9000/log) for more detail.: timed out waiting for port 9000 to be started after 2m0s

/tidb-deploy/tiflash-9000这个文件下生成的文件直线上升，把我100G硬盘都占慢了，后来我就把这个文件夹下所有文件删除了，现在启动后不往里面写东西了，请问这个文件夹里的文件内容大师怎么回事，还有怎样设置才能继续往这里写日志，tiflash_error.log找不到了
