Symptoms

当共享名称包含“/”字符时，具有导出路径的 NFSv4 装载失败。 
mount -o vers=4 xx.xx.xx.xx:/<share name contains "/"> /mnt/nfsv4
mount.nfs: mounting xx.xx.xx.xx:/<share name contains "/"> failed, reason given by server: No such file or directory
尝试使用 NFSv3 装载到同一导出路径成功。

Cause

NFSv4 客户端无法装载包含“/”字符的共享名称。

Unisphere CLI 文档声明以下内容：
NFSv4 客户端不能使用包含“/”字符的名称装载共享。
相反，客户端必须使用共享路径。

Resolution

如果满足上述条件，请使用共享路径（本地路径）而不是共享名称（导出路径）进行装载。

Additional Information

以下是 NFS 共享名称包含“/”的示例。
这是 Unisphere UI 屏幕的示例，其中
在此示例中，如果文件系统下有一个名为“/AAA/CCC”的文件夹，则在尝试使用 NFSv4 装载该文件夹时会装载该文件夹。
如果文件系统下没有文件夹“/AAA/CCC”，则会显示“No such file or directory”错误。

使用 NFS 版本 3 通过“导出路径”装载 
# mount -o vers=3 xx.xx.xx.xx:/AAA/CCC /mnt/nfsv3
使用 NFS 版本 4 通过“导出路径”装载 
# mount -o vers=4 xx.xx.xx.xx:/AAA/CCC /mnt/nfsv4
mount.nfs: mounting xx.xx.xx.xx:/AAA/CCC failed, reason given by server: No such file or directory
使用 NFS 版本 4 通过“本地路径”装载 
# mount -o vers=4 xx.xx.xx.xx:/testfs/AAA/BBB/CCC /mnt/nfsv4
