Nginx无法读取文件时,有多个挂载点,有不同的扇区大小时,使用directio。
我们的服务器在Nginx的根文件夹下安装了不同的硬盘驱动器。我们所有的旧磁盘都有512的扇区大小,当我们更换磁盘时,Nginx突然无法从该磁盘读取文件。
服务器上似乎没有什么问题,我们可以列出/读取文件没有问题,但Nginx不能。在error_log中向客户端发送响应时显示失败(22:无效参数)。

4096的新硬盘

问题是Nginx使用了512的directio_alignment,但当硬盘大小为4096时,这似乎不起作用。
将directio_alignment设置为4k解决了这个问题,Nginx现在可以从512和4096扇区的驱动器读取数据。

我在nginx 1.22.1 / Debian 12上遇到了同样的问题。
我刚刚关闭了sendfile,它工作了:
