VMware Snapshot failed for NFS volume

[Neek]

I used to export iscsi to my VMware server but cut over to NFS. Since then, I have been unable to get successful snapshots. I removed and re-added the VMware host, and according to the VMware logs, root @ my freenas box is logging in successfully, but using 0 APIs. I found a few other threads about VMware failing due to VMs that can't be quiesced, but I don't think that's my problem, as I have no logging on either FreeNAS nor VMware to make me think that's the issue.

I'm running FreeNAS 11.0-U4 and VMware ESXi 5.5.

Any suggestions about how to troubleshoot this are very welcome.

Not 100% sure of this, but I think VMware Snapshots require a vCenter instance or a more recent version of ESXi.

I had snapshots working when I was using iscsi so I don't think this is a problem with the ESXi version (but thanks for the response).

ZFS snapshots or ESXi snapshots?

These are ZFS snapshots but they are supposed to idle ESXi first (as found in Storage -> Vmware-Snapshots in the FreeNAS GUI)
