If you reboot the head node, you should reboot the cluster nodes also using "cshutdown -r". If you don't, then the nfs mounts on the compute nodes stop working and you see problems like you are having with ssh asking for passwords.
For passwordless ssh to work the way oscar is set up, all the /home directories have to be mounted via nfs from the head node. Since the nfs mounts all broke when you rebooted the head node, fluent stopped working too.
