When rebooting controllers, the nodes all hang and require a reset via Console to complete reboot. Once you do this one time, the following reboots will all be successful.
This was found to be caused by the auto dependencies systemd-fstab-generator, in this case we should add the mount option '_netdev'
Mount units referring to local and network file systems are distinguished by their file system type specification. In some cases this is not sufficient (for example network block device based mounts, such as iSCSI), in which case _netdev may be added to the mount option string of the unit, which forces systemd to consider the mount unit a network mount. Mount units (regardless if local or network) also acquire automatic Before= and Conflicts= on umount.target in order to be stopped during shutdown.

Fixes an issue when rebooting with an NFS mount.
_netdev mount option helps fix a timing issue when rebooting.
This looks like we're hitting an issue where we're using
network instead of NetworkManager and that systemd doesn't
unmount the NFS shares before stopping network.
