I am unable to disable rootsquash on a PowerScale NFS export. 

What I've Done:

1. Disabled root mapping (aka rootsquash) via:
   • PowerScale WebUI → Export Settings → "Do not map root users".
2. Confirmed via CLI:
   • isi nfs exports view <export_id> --zone <zone> shows map-root-enabled: false.
3. Validated client IPs:
   • Clients are listed in Clients, Always Read/Write Clients, and Root Clients.
4. Expected Behavior:
   • Files/directories in client mount should be owned by root (UID 0), not nobody.

Unfortunately my expectations have not been met:(
