DHCP, OSCAR cluster installation, VMware server and PXE-boot problem.
Hi!
I seem to have a talent for doing things at the wrong time, in the wrong order or just in general messing things up. Sigh... I am installing a little cluster with OSCAR 5.1rc (which I have to do for a postgrad chemistry project. Yes, the connection between clusters and chemistry isn't immediately apparent, but it's there...) At the second last step, when the cluster should be completed, it failed. There were problems with torque and maui finishing the configuration. I have a server node, and added one normal compute node. Then, perhaps because my supervisor was wanting to see some progress, and because I had a few hours in which I couldn't continue with other work, I loaded VMware server 2.0 on the server node as we have a small partition for XP. (Running Fedora 8 on the larger partition). Now, when I wanted to add some more nodes to the cluster, they don't manage to boot by way of the network. This is what I get on the nodes: PXE-E11 : ARP timeout PXE-E11 : ARP timeout PXE-E38 : TFTP cannot open connection PXE-M0F : Exiting Intel Boot Agent So I guess the trouble-maker is the VMware and the DHCP. The VMware install said the following: Code:
This system appears to have a DHCP server configured for normal use. Beware Code:
# and similarly for vmnet1. Is there some other dhcpd file that I should change as shown in 1) above? Secondly, I don't really know how to do 2). Is 2) a once off thing, or what? Thirdly, I don't need VMware urgently until the cluster is up and running. Could I uninstall VMware, and just install it again later? Hm, but I'm afraid it might cause problems again. I would prefer to sort out the problems now, and not have some mysterious problems popping up later. Any advice would be greatly appreciated! |
Hi! I uninstalled VMware, but now I am getting this:
PXE-E32: TFTP open timeout My /etc/dhcpd.conf file (which I mandaged to find in the meantime) looks like this. Code:
#################################################################### Code:
allow bootp; Any advice would be appreciated! |
I added the "allow's" and it didn't make any difference.
I'm rather depressed. |
Solved the problem
For the PXE-E32: TFTP open timeout problem, disable your firewall properly. That is, don't do it via the gui. Use #service iptables stop, and check these sites
