而 overlayfs 文件系统,就会用到 d_type 这个东西用来文件的操作是被正确的处理了。换句话说,docker只要使用 overlay 或者 overlay2,就等于在用 overlayfs,也就一定会用到 d_type。所以,docker 提供了 docker info 此命令,用来检测你docker服务,是否在使用overlay的时候正确的使用 d_type。如果用了 overlay/overl...

d_type 从 Linux 2.6 内核开始就已经支持了,只不过虽然 Linux 内核虽然支持,但有些文件系统实现了 d_type,而有些,没有实现,有些是选择性的实现,也就是需要用户自己用额外的参数来决定是否开启d_type的支持。 为什么docker在overlay2(xfs文件系统)需要d_type 不论是 overlay,还是 overlay2,它们的底层文件系统都...

The overlay and overlay2 storage driver does not work as expected if the backing filesystem does not support d_type. For example, XFS does not support d_type if it is formatted with the ftype=0 option. Support for these setups has been removed, and Docker v23.0 and up now fails to ...
