Fraction Reserve is set to 100% in NFS volume, any impact?

[netappmagic]

If a volume for NFS export and it's F.R is set to 100%, are there any impacts on the volume? 

As I understand F.R. is only useful in volume with LUN.

If no useful in NFS volume, do I have to change it to 0%, can I just leave as 100%

Thanks!

FR is irrelevant for NAS only volume - its value is not used in this case.

[netappmagic]

Right. Understood. NFS volume doesn't use F.R.

Should I change or any reasons to change the volue to 0%? since all being set to 100% here

[aborzenkov]

100% had always been default. There is no reason to change it.

I have experienced capacity impact, when using NFS VAAI.

Note that the lazy,eager zeroed VMDK format usecase.
