The NFS server does not support NFS version 3 over TCP – QNAP

December 26, 2015

After recently powering-on an ESXi host I found that all of the NFS Shares hosted on my QNAP TS-231 storage appliance were disconnected.  I first attempted to reconnect by using the vSphere Client option Rescan All in the Configuration –> Storage –> Datastores pane.  When that was unsuccessful I attempted to manually remove and re-add the datastore.  Unfortunately that too was unsuccessful.  I didn’t want to restart my QNAP appliance so I decided to restart the NFS service.  First I enabled SSH on my QNAP appliance.

Once SSH was enabled I connected to the QNAP appliance from my Mac by using the Terminal application ssh admin@

The last step was to restart the NFS service.

Once I successfully restarted the NFS Service, I re-opened the vSphere client and clicked on Rescan All.. once more.  This time access to my shares had been restored.
