Symptome
Upon creating a file system (FS) with an identical name to the SNS name, SNS export cannot be mounted using NFSv4.
Customer Impact:
SNS export using NFSv4 will fail to mount. As a result, access to the SNS links will fail and be redirected to link targets.
This issue affects: PowerFlex, PowerMax, and PowerStore

Ursache
This issue is due to SDNAS using a single namespace.
Lösung
Workaround:
Re-create the namespace with a different name.
The FS name should be different from the SNS root hosting file system name.
Important: Use the NFSv4 version mount option explicitly while mounting the namespace to avoid auto-failback to NFSv3.
