How is fast cloning supposed to work on vSphere NFS and VVOL datastores?
I have UnityVSA installed and I have created legacy NFS datastore and VVOL NFS datastore, I also have EMC NAS VAAI plugin installed and VASA VP configured. Any time I clone a VM full clone is created, I have verified from ESXi hosts vpxa.log that NAS VAAI plugin is being used when cloning on NFS datastore.
Is VSI required for fast cloning on Unity?
Can I force NAS VAAI plugin to create fast clones instead of full clones?
The Unity array does support fast cloning using VAAI and VASA 2.0 (VVols). Fast cloning is a feature used by tools such as Horizon View not available directly from the vCenter GUI.
Same issue here, would love to have fast cloning work. The documentation suggests that it should work and the GUI shows a parent object but when I clone a VM it creates a totally separate entity.
IF you use the proper software that explicitly reqeuests a file-level clone than it does work - see Wei's answer above
a regular clone command from vSphere will not
VSI should but i havent checked that in a while
you could file a product enhancement request (PER)
