    Hi @ nvazquez, 
    Are you sure that the problem is caused because we are not telling the NFS protocol version
to the mount command?
    
    If you a look at the doc in [1] and [2], you will see that if we do not provide a NFS
protocol version to be used, it (the mount program) will first try version 4, then 3, and
version 2 as the last one.
    
    If the default behavior of mount is to try every possible protocol available, I do not
see why we need to add some extra code to enable us to specify one. 
    
    Wasn’t your problem caused by something else?

> After starting secondary storage VM, secondary storage tries to be mounted but fails
with error: {{Protocol family not supported}}
> It was found out that adding {{-o vers=X}} to mount command it would work, where {{X}}
is the desired NFS version to use. 
> If it is desired to mount a store with a specific NFS version, it has passed in {{image_store_details}}
table for a store with id {{Y}} as a property:
> ||store_id||||name||value||
> |Y|nfs.version|X|
> Where X stands for NFS version
