尝试访问我创建的目录后，Linux/Debian 中的权限被拒绝

我遇到了问题，gcsfuse但我也遇到了基本权限问题，这使得这个问题与这个论坛相关。我已经通过 SSH 进入了 google cloud 远程虚拟机实例。我可以毫无问题地创建目录并将存储桶安装到安装点。但完成后，我无法进入目录并列出文件。有问题的目录是temp_dir3 在这个系列命令中，我尝试更改所有权，但系统卡住了，我不得不按下控制键 c

kylefoley@kfoley76:/mnt/disks$ sudo chmod o+rx -R /mnt/disks/temp_dir3
kylefoley@kfoley76:/mnt/disks$ cd temp_dir3
kylefoley@kfoley76:/mnt/disks/temp_dir3$ cd ..
kylefoley@kfoley76:/mnt/disks$ sudo gcsfuse deduction3 /mnt/disks/temp_dir3
Using mount point: /mnt/disks/temp_dir3

kylefoley@kfoley76:/mnt/disks$ cd temp_dir3
-bash: cd: temp_dir3: Permission denied
kylefoley@kfoley76:/mnt/disks$ sudo chmod o+rx -R /mnt/disks/temp_dir3

^C

在这个系列中，我认为 temp_dir3 可能因为文件太大而卡住了。毕竟它们占用了大约 200 GB。所以我创建了一个新目录并安装了一个较小的存储桶。但这也没有用。我也再次尝试了 temp_dir3，但也没有用。

kylefoley@kfoley76:/mnt/disks$ sudo mkdir -p /mnt/disks/temp_dir4
kylefoley@kfoley76:/mnt/disks$ sudo gcsfuse deduction1 /mnt/disks/temp_dir4

-bash: cd: temp_dir4: Permission denied
kylefoley@kfoley76:/mnt$ sudo chmod a+w /mnt/disks/temp_dir4
kylefoley@kfoley76:/mnt/disks$ cd temp_dir4
-bash: cd: temp_dir4: Permission denied
kylefoley@kfoley76:/mnt/disks$ sudo chmod o+rx -R /mnt/disks/temp_dir4
kylefoley@kfoley76:/mnt/disks$ cd temp_dir4
-bash: cd: temp_dir4: Permission denied
kylefoley@kfoley76:/mnt/disks$ sudo chmod a+w /mnt/disks/temp_dir4
kylefoley@kfoley76:/mnt/disks$ cd temp_dir4
-bash: cd: temp_dir4: Permission denied

以下是 temp_dir4 文件夹的统计数据。只有卸载存储桶后才能获取统计数据

您必须使用“root”帐户用户来执行此操作：

sudo -i

现在您拥有所有权限。完成后

logout
