Remount an NFS Datastore without rebooting

NFS is a great storage solution within a VMware vSphere environment but when the connection to the NFS server is lost, you’re in big trouble. In most circumstances some virtual machines are still connected to the NFS Datastore and since it’s in use, you cannot delete and recreate it. I’ve tried this by using the vSphere Client and trough the command line but didn’t succeed. In the end there’s no other alternative than rebooting the ESX host, or is there… If you want to find out how to remount an NFS Datastore you better watch this online training.
