-bash-3.2$ cd ../Inbox
-bash: cd: ../Inbox: Permission denied
文件系统是 XFS。目录上是否有 ls -l 不会显示的权限？我是目录及其内所有文件的所有者。我可以使用 sudo 来修改文件权限或查看文件夹的内容，但我需要“管理员”可以访问它们。
有什么想法吗？我会定期检查这个问题，所以如果我需要用更多信息更新它，请告诉我。
谢谢

第二次编辑：为迈克详细说明。
收件箱位于以下位置
/home/admin/MyLibrary/MyVideos/Inbox
/home/admin/MyLibrary/MyVideos/Movies
该系统是一个 Netgear Stora NAS 盒，我有 root 访问权限。/home/ 文件夹作为 smb 共享安装在房子周围的各种计算机上。文件夹 /Inbox 无法在任何这些机器上打开（它们都以“admin”身份连接）。当我使用“admin”凭据通过 ssh 进入盒子时，我也无法访问该文件夹。该文件夹是通过 NAS 上托管的 Web Admin 页面创建的。Inbox 文件夹的用户/组以前是 apache:www（预计该文件夹是由 Web 应用程序创建的），但我以 root 用户的身份 chmod/chowned 该文件夹，试图授予管理员用户（因此其余连接的机器）访问文件的权限。很抱歉之前没有包括这一点，我不确定它是否相关，也不想混淆情况。
-谢谢
第三次编辑再次抱歉 - 看起来这个 NAS 运行的是 Red Hat 的一些自定义版本，而不是之前所说的 Debian - 我不确定这是否有区别
答案1
这肯定不是 SELinux，但看起来你可能对该文件夹有 ACL。你可以通过运行 getfacl 来验证。以下是示例：
[root@localhost ~]# getfacl install.log
# file: install.log
# owner: root
# group: root
user::rw-
group::r--
other::r--
这可能解释了为什么您无法以管理员用户身份访问它，即使您拥有完全权限。
为了解决这个问题，您需要使用 setfacl 修改 acl，以提供对该文件夹的完全访问权限或允许管理员用户访问该文件夹。再次，以下是一个例子：
[root@localhost ~]# setfacl -m u:apache:rx install.log
[root@localhost ~]# getfacl install.log
# file: install.log
# owner: root
# group: root
user::rw-
user:apache:r-x
group::r--
mask::r-x
other::r--
如果您熟悉 Unix 风格的权限，那么您就会掌握它。请执行“man setfacl”以获取有关使用 setfacl 的更多说明。
编辑：我检查了一下，XFS 支持 acl。所以很有可能是这个。
以下页面可以更好地说明如何使用它们：
答案2
您可以在这里找到答案：http://www.openstora.com/phpBB3/viewtopic.php?f=1&t=1506
您的 NAS 可能设置了 JBOD，权限不匹配。查看 /mnt/disk1 和 /mnt/disk2，并检查每个权限。您会发现它们不匹配。在两个地方将它们更改为正确的用户，您便可以访问。
答案3
SELinux 是否已启用。您可以在 /home/admin/MyLibrary/MyVideos/Inbox 上运行 ls -Z 吗？
