Hello, I am a new administrator on a legacy NetApp system running ONTAP 9.8. I have some experience using Netapps. Q1: Is is able to create shares inside NFS Volumes? I can do this with CIFS volumes but cannot figure a way to do this NFS, Linux access only (not mixed) Q2: I need to migrate shares from an old LDAP server to the corporate AD server. The NFS has an LDAP configuration setting. Will the LDAP override the AD setting if I am authenticating to the AD ? I need to migrate PCs one at a time. My problem is I am mounting the share on a Ubuntu 22 VM that authenticates to the AD as root, but it is not recognizing the AD groups as write permissions. If I create a single user folder and chown the folders, I am able to write to the folder. Maybe 2 different unrelated issues or I am not using NFS correctly Thank you for replies.

I need to clarify whether ONTAP can dedup and compress data blocks locked by snapshot. Does below command vol efficiency start -volume vol1 -vserver vs1 -scan-all -shared-blocks -snapshot-blocks dedup and compress data blocks locked by snapshot ? if not, does it mean snapshot blocks can not be deduplicated or compressed ?

Hi all, I recently inherited an already configured AFF-A300. It already has some volumes, exported via NFS3 and they all work fine. Today I tried to add a new volume via the Ontap system manager, but the mount fails: # mount -v -t nfs vrc01n01b:/proj_rfip_hki /root/hki

We use OnTap 9.x and all users have personal shares. We have a use case to make some of these personal share's read-only. Aside from actually setting the read-only attribute on the folders/files therine is there any method to mark a personal share as read-only at the Ontap side?
