      PS> I think what trips me up is, I am just trying to find one happy path, and I don’t think that has been revealed yet to me (with our hardware, at least). It’s mind boggling to me the things that do work, when they work, and the things that do not work, and for reasons I am not equipped-enough to handle yet. Even now, understanding as much as I do, I circle back and ask simple questions, such as, why does the swap partition fail to image when deploying an EXT formatted drive. Or, why can I set the system up for LVM, capture and deploy the disk, and only then am I able to boot into ‘/dev/sdb’ with the settings I provided; however, fails to do a simple SANBOOT.

      Also, here’s an image of the boot drives post-installation of Ubuntu…

        Yeah, I have to head home for now. I will get this information ASAP tomorrow or tonight if I can.

          I had issues copying the drive as EXT4 in the past too. The swap drive would always be mis-aligned I believe, and the system would create a new one and then I’d have fstab issues always.

          This is known about. Here’s lots of info on that, and options too:

            @dholtz-docbox San boot releases to the first found HDD, or sda in your case. Exit should release to bios which then finds the disk with the right boot active flag. I’d recommend trying exit first. If this doesn’t work then try grub, though it defaults to first HDD. The best grub would be first found windows but these systems aren’t windows systems.

              @Tom-Elliott : That’s what I started to think last night, so that makes sense. I wanted EXIT to work as you described, but it throws a chainloading error each time. I am actually going to… just install the drive as EXT4. I mean… /dev/sdb is just /dev/sdb, one way or the other, right? I am hoping the system works fine, and then I can just do single disk targeting the second drive, hoping that it is more reliable.

                A chainloading error is better than the other stuff you were describing. Let’s focus on that, please provide a photo of the error, and the MAC address of the computer you tried on, and the FOG Server’s IP address.

                  No problem. Let me re-install the system with LVM - I was trying other things in the interim. I will provide an image as soon as that is complete.

                    Nah, please go with Ext4. We will explore the EXIT option with that setup.

                      Unfortunately, I have to move forward with the LVM installation for now. Given the time until our next release, it is too risky to greenlight the change to EXT. That said, I had the same issue with both SANBOOT and EXIT w/ the EXT install, so the problem is similar I feel - wild guess.

                      I was also hopeful that installing EXT would eliminate the extra boot options in my BIOS. It seems that was not the case, so maybe they are related to Server Edition instead? I just find it odd that, when installing Ubuntu to the disk, that I can no longer boot from the disk and must boot from one of those Ubuntu options. Which one also has relevance, as the other one appears to have no operating system on it. Perhaps it’s the swap?

                      As far as the other information…

                      • host mac => 08:60:6e:fa:05:af
                      • server ip => 10.1.10.42

                      and here’s an image of the boot output…

                        @dholtz-docbox Ok, in your browser click on this link and give us a copy of the output:

                        10.1.10.42/fog/service/ipxe/boot.php?mac=08:60:6e:fa:05:af

                        It appears you have your DHCP server setup for FOG, and you also have dnsmasq setup for FOG? This isn’t necessary. Choose one or the other, I’d suggest using the full DHCP server.

                        And what boot file are you using again? I don’t think you listed that earlier. You can quickly find this just by looking at what you have set in DHCP option 067.

                            As far as whether I have DHCP setup for FOG and DNSMasq, I should only have DNSMasq? Is there a way to validate this? The .fogsettings for the server are as follows…

                              You had me thinking…

                              One of the other VM’s on the network I used, at one point, to do an installation, where it setup using FOG’s DHCP. Is it possible something is still lingering on this machine? I am going to shut it off and give it a whack, in the mean time…

                              Edit> Nope. No difference.

                                Read what your screenshot says.
                                “Duplicate option 66 (next server) from DHCP proxy and DHCP server.”

                                This means your DHCP server is configured for FOG, and dnsmasq is configured for FOG. dnsmasq will refuse to run on a box that is also serving DHCP, so these two things are on two different systems. You don’t need both, and a full DHCP server is superior by far.

                                Use wireshark with the bootp filter to determine where the other DHCP server is, and do some ipconfig /release /renew commands to get them to respond - but you should already know where it is really.

                                Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

                                    Yeah, I was wondering about that line - it has been bothering me. I have never used wireshark, so let me grab it and look around.

                                    You have a lot more output 😞

                                    I have not edited anything though; I have only run the installfog.sh script over the existing installation.

                                    Let me go and determine who else is serving DHCP real quick.

                                    Edit> Which machine should I be using wireshark on? I’m not quite sure how to use the tool in the requested manner.
                                    Edit> Nevermind. Wireshark was starting up with one of its windows resized to its minimum height - the window which lists the packets. I am looking through it now.
                                    Edit>
                                    0_1476989636971_upload-8ae29e1f-ba2f-41dd-9538-05e72c0cd3d0

                                    Am I right in looking at this, in that, both 10.1.10.1 and 10.1.10.42 are serving DHCP, where only, w/ DNSMasq, 10.1.10.1 should be serving it?

                                    Edit> I believe that is right, reading into how DHCP works. There should only be one DHCP Offer, correct? Both 10.1.10.1 and 10.1.10.42 offering would indicate that 10.1.10.42 is setup, somehow, to serve its own DHCP? I guess my next question is, if my dnsmasq.conf is correct, what is lingering that is causing 10.1.10.42 to also serve DHCP.

                                      @dholtz-docbox TBH: I did not read the entire thread here, but your dhcp process looks normal if you are running dnsmasq in dhcpPROXY mode. In that case your primary dhcp server is 10.1.10…42 and 10.1.10.1 is the dnsmasq.

                                      Looking down a bit more 10.1.10.1 is giving the ack so that tells me that 10.1.10.1 is your dhcp server. That way I rad this pcap is that you DO have two dhcp servers on your subnet. If .10.1 is your defined dhcp server for your subnet, you need to understand what .10.42 is doing. It should not be issuing an Offer if it has nothing to offer the client sending the discover.

                                        @george1421 : I am not sure if our terminology is in sync, but to clarify… the router which handles DHCP is 10.1.10.1 and the FOG Server is 10.1.10.42. When you say “primary DHCP”, from whose point-of-view is that? My current assumption is that the primary DHCP would be the one serving IP’s; where the FOG Server would be the DNSMasq?

                                        Further, I agree, 10.1.10.42 should NOT be offering anything. But when I look at Wireshark, 10.1.10.42 the one with a boot filename, where 10.1.10.1 has no real supporting information.

                                        That said… does my dnsmasq.conf need to be flipped around, such that…

                                        dhcp-boot=undionly.kpxe,,10.1.10.1
                                        

                                        and…

                                        dhcp-range=10.1.10.42,proxy
                                        

                                        … or something like that? Curious if I had something flipped around incorrectly.

                                          @dholtz-docbox one of the two are incorrect.

                                          Lets go this way. Your dhcp server is .10.1 so then is your fog/dnsmasq server .1.42?

                                          If that is the case both IP addresses below need to point to your FOG/dnsmasq server or the target will not pxe boot. In this setup dnsmasq is only supplying the {next server} and {boot file} and not an ip address that comes from your dhcp server.

                                            @george1421 : Yeah, I noticed that - that PXE won’t boot this way, which makes sense. I reverted the changes. I guess what I have been trying to figure out is what Wayne mentioned, that the, “Duplicate option 66 (next server) from DHCP proxy and DHCP server,” message is present. So far, everyone of my network captures has yielded the aforementioned results. Where the only thing that strikes me as odd is the fact that both 10.1.10.1 and 10.1.10.42 are trying to make an offer. That said, only 10.1.10.1 ACK’s, but it has no boot filename or anything. If everything is setup the way it should be, 10.1.10.1 should be supplying “undionly.kpxe” in its boot filename, right?

                                            Edit> Oh, re-reading your previous post, and reading what I wrote again, something might have clicked. So… 10.1.10.1 is serving the IP and 10.1.10.42 is serving the next-server, which is its IP, 10.1.10.42, correct? So… this would be typical behavior, if that is all correct… Which brings me back to not being sure why there is a duplicate option 66.
