症状

NFSv4 mount with export path failed when the share name contains the "/" character.
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
Attempting to mount with NFSv3 to the same Export Path is successful.

原因

NFSv4 client cannot mount a share name that contains the "/" character.

The Unisphere CLI documentation states the following:
An NFSv4 client cannot mount a share using a name that contains the "/" character.
Instead the client must use the share path.

解决方案

If the above condition is met, use share path (local path) instead of share name (export path) for mounting.

其他信息

The following is an example where the NFS Share Name contains "/".
This is an example of the Unisphere UI screen with
In this example, if there is a folder named "/AAA/CCC" under the file system, the folder is mounted when attempting to mount it using NFSv4.
If there is no folder "/AAA/CCC" under the file system, a "No such file or directory" error appears.

Mount with "Export paths" using NFS version 3
# mount -o vers=3 xx.xx.xx.xx:/AAA/CCC /mnt/nfsv3
Mount with "Export paths" using NFS version 4
# 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
Mount with "Local path" using NFS version 4
# mount -o vers=4 xx.xx.xx.xx:/testfs/AAA/BBB/CCC /mnt/nfsv4
