YES! That solved the problem. I think I did run update_client. This
is a NASTY bug!
To fix my nodes, I booted into each one with a rescue disk and ran
chroot /mnt/sysimage
systemconfigurator --configsi
It gave me an error message about the ram disk. I then rebooted, and
everything is running fine! Thank all of you for the great support.

|Did you happen to run an update_client on the nodes at
|some point? This will have wiped out some of the
|configuration that was done by systemconfigurator,
|which is who creates those files. The networking files
|are probably missing/incorrect also. Currently running
|update_client is not supported on an OSCAR cluster for
|this reason.
|
|If that's the case, you should be able to run
|systemconfigurator again on the nodes from a booted
|rescue disk. You'll have to mount all the filesystems
|and run it chrooted. You can steal the proper command
|from the autoinstall script for the image in
|/var/lib/systemimager/scripts.
