We are also missing this feature from vnx/isilon. Unity does not have rquotad support at the moment. Maybe on some later release? Other annoyance on nfs is the user visible snapshots which cause circular fs errors on many commands. (vnx series hide them under non visible .ckpt folder)
Never noticed that the VNX rquotad does not work for the VDM's as all of our quota using NFS shares were made when NFS was not supported on the VDM. Good to know.
Unity chekpoint on the NFS looks like this:
[XXXX scratch]$ ls -la |grep -i .ckpt
drwxrwxrwt. 775 root root 108544 Feb 10 16:33 .ckpt_2017-02-10_14.35.00
drwxrwxrwt. 789 root root 108544 Feb 13 16:09 .ckpt_2017-02-13_14.35.00

This almost certainly means that you have a corrupted file system.
NOTIFY YOUR SYSTEM MANAGER.
The following directory is part of the cycle:

The following directory is part of the cycle:

So they are directly on the root of the share and visible to the ls -la command. (on VNX this was datamover parameter controllable setting with default of being hidden "showChildFsRoot " if I remember correctly)
With nfs 4 you can event see the .ckpt folders as a mounted new FS on the client after accessing the snapshot folder.

I guess that good old rquotad is still active in Unity but havent checked - if thats what you mean
see the VNX NFS docs
There is also the quota.useQuotasInFsStat param that you can now also set in Unity
if thats what you mean

please post your ls output from NFS client - .cpkt dir should be invisible just like on VNX
If you feel strongly about rquota support on Unity I would suggest to open a product enhancement request via the proper route
VNX does support rquotad - see the VNX quotas Manual - but not against VDMs
