Any way to force NFSv3 on Direct NFS Access?

[mikeely]

We just got some shiny new SAN hardware that has NFSv4 enabled, which the backup proxies are attempting to use and are generating noise like so:
kernel: VFS: Lookup of 'tintri' in nfs4 0:46 would have caused loop

Rather than get into the weeds of NFSv4 I'd rather just force the proxy to v3. How can this be done?

Hello,
I suggest to fix the root cause. There is a registry key to define per share which NFS version to use, but it's marked with "special use only" and "can crash VBR server". The key can be obtained via support, but I would not use it in production.

Best regards,
Hannes

I would say, let´s find out the real issue and then fix this on Veeam or storage side?
