DHCP problems on storage nodes

george1421

The error message is a bit confusing, but when we typically see this, is when the FOS client can’t reach the FOG server, or the fog server IP address has been changed since FOG was installed.

@george1421
What files do i need to check and make sure they are pointing to the proper IP or hostname?

george1421

@greg-plamondon I thought I had a tutorial on this but I guess not.

In the fog configuration there are 2 places (I think, pretty sure)
In the storage node configuration there is 1 place
and then in the linux console, /tftpboot/default.ipxe

But if you have changed the IP address there is another process to fix it. You correct the top 3 and then ensure the IP address is set correctly in /opt/fog/.fogsettings file then rerun the fog installer to fix the rest of the bits.

@george1421
I checked the storage node and its looks correct:

#!ipxe
cpuid --ext 29 && set arch x86_64 || set arch i386
params
param mac0 ${net0/mac}
param arch ${arch}
param platform ${platform}
param product ${product}
param manufacturer ${product}
param ipxever ${version}
param filename ${filename}
isset ${net1/mac} && param mac1 ${net1/mac} || goto bootme
isset ${net2/mac} && param mac2 ${net2/mac} || goto bootme
:bootme
chain http://10.21.40.39/fog/service/ipxe/boot.php##params

the fogserver was installed with this IP.

Greg Plamondon

Just a heads up… I wasn’t having this issue until I recently updated, but I cannot remember what build I was on.

george1421

@greg-plamondon Well if you look at your first post (second picture) FOS is getting an IP address of 10.21.100.115 but then it restarts. There should have been another message between the adding dns 192.168.10.3 and the udhcpc restarted message, saying that it couldn’t reach the fog server. Maybe that message only appears in debug mode, or your kernel logging level is wrong.

So it looks like you have scheduled a capture or deploy with this system? If so lets key in the following url into a browser replacing <mac> with the real mac address of this computer

http://<fog_server_ip>/fog/service/ipxe/boot.php?mac=c0:3f:d5:9d:e9:50

That should give you the ipxe menu for this boot process. I’m interested in the kernel parameters being sent to FOS. They will be displayed when you key that url in.

george1421

ok looking at your first picture a bit more where / why are these two IP addresses in play here

10.21.40.39
192.168.10.238

I would expect to see one address for your fog server, unless you have a storage node 10.21.40.39 and the master fog server at 192.168.10.238

Additionally during dhcp discovery on FOS its posting dns servers in the 192.168.10.x range with the target computer being given an IP address in the 10.21.100.x range. WTF??

Greg Plamondon

@george1421

10.21.40.39 is the storage node for that location.
192.168.10.238 is the main fog server that is the management interface.

george1421

@greg-plamondon ok run the query I posted in red below against your fog master server.

I did amend my previous post with the WTF comment. You have Ip addresses all over the place.

Greg Plamondon

@george1421
run it from the client i am trying to image? or from any workstation?

@greg-plamondon as long as you still have the job scheduled from any computer that can reach the master fog server.

also just because your network is a bit more complex than it appears on the surface. You are sure that the 10.21.100.x subnet can physically reach the master fog server at 192.168.10.238. I’m going to say yes because we see that in the pxe booting process. But during FOS startup it has to be able to connect via http to the fog server.

Greg Plamondon

@george1421
oops i canceled the job…

george1421

@greg-plamondon if you are going to reschedule the job, tick the check box that says debug and then pxe boot the target computer. Let see if that gives us any new info.

Sebastian Roth

@Greg-Plamondon Take a look at the Storage Settings in your FOG web UI. I am fairly sure you’ll find the old IP there.

george1421

@sebastian-roth Am I missing something, what he just posted looks correct with a master fog server and a storage node.

george1421

@greg-plamondon This looks right.

So a little bit more background on this. Are all target computers at this location doing this or only just this one computer?

Greg Plamondon

@george1421

Its doing this at all locations. I have 30 locations
