我有一台本地服务器，其中有共享，用于本地计算机备份内容。
服务器有一个备份用户 (1002:1002)。
客户端有用户 alex(1000:1000)，他也在该机器上的备份用户 (1002) 组中。
为了查找错误，我在代码片段中以备份用户身份登录。
有时（使用 chmod 777）我可以用 nano 编辑测试文件，有时不行，有时在第二次尝试时可以成功。所以这里肯定有什么可疑之处。
计划是让用户 alex 能够完全访问文件夹 snapraid_ignored 的内容。
服务器运行 Proxmox，客户端运行 Antergos Gnome。

我通过尝试用 nano 编辑测试文件或尝试用 重命名它来测试写访问mv。
A类似问题这里建议尝试使用 lsattr：
root@pve:/home/fileserver/storagepool/Backups_external/snapraid_ignored# lsattr
--------------e---- ./Ubuntu
--------------e---- ./piRadio
--------------e---- ./Tbox
--------------e---- ./test
--------------e---- ./Alex Dator
编辑
当我通过 ssh 进入我的 Raspberry Pi 时，它运行良好，我可以在共享上添加和编辑。我在 中使用它/etc/fstab。
192.168.1.10:/home/fileserver/storagepool/Backups_external/snapraid_ignored /media/backup_on_server nfs _netdev,auto,noatime,nolock,bg,intr,tcp,actimeo=1800 0 0
在 Raspberry Pi 上，我没有备份用户，我以用户 pi 的身份执行所有操作。
因此，我在尝试使其工作的机器上做了同样的事情。我在 fstab 中添加了相同的行。我还删除了备份用户和组，并将自己从中删除。
这没什么区别。
答案1
我不确定为什么它会起作用，但将所有权更改/home/fileserver/storagepool/Backups_external/为 backupuser:fileserver（而不是 backupuser:backupuser）却起作用了。我现在可以从我的电脑上添加、删除和编辑服务器上的文件。
