about nfs mount command

I'm new to NetApp, but let me ask you the following questions.

I bought the FAS2750 and I don't have it yet, but the Ontap version is probably 9.8 or higher.

Now, I am making an NFS mounting from linux (rhel7) to another NAS storage with the following command.
#FSTAB command
<MountServer>:/mnt/Dir1 /mnt/Dir1 nfs4 default,soft 0 0

 

When changing from NAS to FAS2750, Linux will also be upgraded from 7 to 8.
If so, please give me some advice on how to change this command.


Assuming the following command, I don't know whether 4.1 or 4.2 is the correct answer for nfsvers = 4.X.
<MountServer>:/mnt/Dir1 /mnt/Dir1 nfs default,soft nfsvers=4.X 0 0

 

Thanks

From the client side, you will use it as you use any NAS server. 

The mount command will be the same with different  <Netapp-Vserver>:/junction-path

What are junction paths?

The answer is a matter of personal preference and need of features. Performance difference is negligible.

 

I'd suggest reviewing the RFC for each version to make a decision:

 

https://datatracker.ietf.org/doc/html/rfc5662

https://datatracker.ietf.org/doc/html/rfc7862

 

As for which version the mount will use if you don't specify a version, the client negotiates the highest version supported by the server. In ONTAP, NFSv4.2 is enabled with NFSv4.1 (there's no independent option), so if you enable v4.1, you've also enabled v4.2. If you want to use only 4.1, you need to explicitly state it in the mount option.
