Dynamic grow and shrink has been available on NFS forever. You STILL can't shrink vmfs, and they've JUST added grow capabilities. Not to mention it being thin provisioned by default. As for performance, I have a tough time believing his performance issues were because of NFS, and not some other underlying bug. I've got MASSIVE deployments of VMware on NFS over 10g that achieve stellar performance (admittedly, it isn't on zfs). --Tim
