CurveFs 用户权限系统调研（已实现） ## 一、 Curvefs测试 • 1. 启动curvefs • 问题1：root用户无法访问挂载目录 • 测试 allow root - 测试allow_other • 参考文献 - 问题2：本地文件系统挂载默认是共享的？ - 问题3：文件系统访问控制是在哪一层实现的？ ## 二、 文件系统权限管理 • 文件类型 • 文件权限 • Using the allow_other mount option works fine as root, in # order to have it work as user you need user_allow_other in /etc/fuse.conf as # well. (This option allows users to use the allow_other option.) ) You need # allow_other if you want users other than the owner to access a mounted fuse. # This option must appear on a line by itself. There is no value, just the # presence of the option. user_allow_other
