We had a similar problem (but had different headnode software) and
copying the modprobe.conf file for the nodes into the image's /etc/
directory allowed us to boot up.
Since your headnode is the same as the compute nodes, you can probably
just copy /etc/modprobe.conf to the image directory (something like
/var/lib/systemimager/images/<image_name>/etc/ ).
Hopefully this helps.

I installed OSCAR on some Dell PowerEdge servers and ran into similar
problems at node reboots. If you look at my notes
(http://svn.oscar.openclustergroup.org/trac/oscar/wiki/TipLDAP) it
should lead you in the right direction.
In your case I would use the drivers mentioned in the
/etc/modprobe.conf instead of the ones I used for the PowerEdge
servers.

Head node and oscar installation goes fine when I reboot the compute

Mounting root filesystem
Mount error 6 mounting ext3
Mount error 2 mounting none
Switching to new root
Switchroot: mount failed 22
Umount /initrd/dev failed: 2

Head node and all the computer nodes are brand new exact hard ware

Subject: Re: [Oscar-users] full installation of FC3
Hi Michael,
BTW, most oscarsamples have xorg-* by default and they would be
installed on the client nodes, right?
So, there may be some x related dependency problems if Jilin needs to
install Xwindows program but it won't be a big problem.
But as Michael mentioned, I would like to confirm how this affects the
performance of the cluster.
Basically I would like to use the gui access/controls of the client
nodes if the performance is not badly affected.
Regards,
- DongInn

The earliest Fedora distribution which is supported by OSCAR 5.0 is
FC4.
That being said, all you would need to do is come up with a fairly
complete RPM list for what you consider to be a "full installation" of
FC3 and use that in place of the sample one. The sample list is
fairly simple and does not include Xwindows.
If there is a particular Xwindows program you need on your nodes, you
may be able to just add that rpm to the list and it might pick up the
rest as dependencies. I am not sure that is a great idea though.
Also, just as a note, OSCAR is not really designed for interactive use
of the nodes, which is why we left Xwindows off the node images to
begin with.

I want to use OSCAR5.0 to manage our cluster. But I donot know how to
