Hello All,

I am still having issues with the cluster I am trying to configure. The 
head node is a DELL R320 and there are several DELL R720 compute nodes. 
I have updated the firmware on all of the servers to the current level.

When I was using ROCKS 6.1.1 I could not get PXE boot to work at all. So 
I then loaded ROCKS 6.2 on the head node. PXE booting worked... However, 
now each of the compute nodes will only boot to the "ROCKS will load in 
3, 2, 1, 0 seconds" prompt and then they hang. They never go to the 
command prompt. I can ssh into any one of them and each is stuck trying 
to load the jexec service.

I strongly suspect that if ROCKS could be running a current version of 
CentOS all would be well.

Is it possible to make a ROCKS bundle with a current version of CentOS? 
Something I could load from scratch as a new head node?

Is it possible to upgrade CentOS in place on the existing head node and 
then insert-ethers the compute nodes?

Any help with this would be greatly appreciated.

Michael
