we have vmdisks with thin provision with Netapp nfsv3 where san disk space auto reclaim is not working. VMs migrated but still and now no data on volume but still space is showing as occupied. Any inputs on it pls. Ontap is 9.1n
You have to check at the storage end or contact Netapp for this. I dont think at ESXi level we can do anything on NFS space reclamation.
