    @george1421 : Absolutely - I just want to make sure I put the right information out there in light of that.

    Will Wireshark explicitly show options 66 and 67? I guess I don’t know how to validate that “the payload of DHCP 66 and 67” are correct. My assumption is that 66 is the “Next server IP address” and that 67 is “Boot file name”.

      @george1421 : I do get into the FOG iPXE menu, so I guess… that’s good to know. It seems to be related to the kernel then…? Which I believe was a path I was on earlier, but wasn’t sure where I was going with it at the time.

        @dholtz-docbox OK while this is just a picture of the pcap, I can see that who ever sent this packet (just off the screen) is sending the next server (option 66) to 10.1.10.42 (hopefully your fog server) an next server (dhcp option 67) as undionly.kpxe this is a proper dhcp offer response from dnsmasq in my opinion.

        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!

          @george1421 : Thank you for clarifying that, that was my suspicion in the end too.

          Also, thank you for taking the time to revisit this topic. I know I am close, given what successes I have had so far.

            You are correct then, its not a pxe/dhcp issue. I guess I need to read the thread now. 😞

                Well, the good news there is that we chopped off a pretty huge segment of what I thought to be wrong. Which was certainly a big question of mine initially. So, pending a few screenshots I linked, I don’t think there is much to catch up on 🙂

                    @dholtz-docbox If you are capturing a linux image that uses LVM, the last I knew LVM disk structure wasn’t supported. Understand I don’t work with cloning linux systems so I can’t give you first hand experience with them. But the last I knew only normal partitions are supported.

                    @Developers Is LVM now supported with FOG 1.3.0RCx?

                      After discussing what I have, the current issue is as follows…

                      My system has two (2) drives; the first drive /dev/sda is not formatted or touched, and the second drive /dev/sdb is formatted with Ubuntu 14.04.5 - Server using LVM. There is nothing complex about the LVM partition - other than it being LVM - as it only contains one primary partition currently - along with any of its other typical partitions.

                      This is where the issue comes into play.

                      I have the host registered with the FOG server, and all I am trying to do is boot the host into its system through PXE. However, every time it goes to boot into the drive, it either hangs - if using SANBOOT - or hits a chainloading loop - when using EXIT.

                      I am told the chainloading loop is easier to deal with than the SANBOOT issue.

                      Since then, I have been trying to narrow down various things, and DHCP configuration was the first to square away.

                        @george1421 Just thinking after I hit the submit button, if you deploy to a target computer and of course it will fail on reboot, but then go into FOG and schedule another deployment , but be sure you pick DEBUG deploy option. Then pxe boot the target computer. That will boot you into the FOG Engine and then drop you to a command prompt after pressing enter a few times. From there you can see check the disk using standard linux tools to see if you can detect anything wrong with the disk structure.

                          @george1421 to bring you up to speed, scroll down and look at the big photo he posted. in there, iPXE is saying: “Duplicate option 66 (next server) from DHCP proxy and DHCP server.”

                          This is the least of the problems though, for some reason the iPXE boot script isn’t getting generated right by the fog server.

                            @Wayne-Workman : Oh! Right - that was the other concern of mine I have on my whiteboard. Thanks for bringing that up again. Should I just… delete /var/www/fog and call .foginstall again on the FOG Server? Or what would be the best way to invalidate this?

                              @dholtz-docbox Looking at a thread from a while ago here:
                              https://forums.fogproject.org/topic/8736/chainloading-failed

                              Assign an image to this host - it doesn’t need to be a legit image, just make one up in Image Management, and assign it. See if the chainloading error goes away or not.

                                I also wanted to update you on this…

                                I believe some services needed to be restarted after upgrading to RC-14, or something needed to be restarted. But after looking at the DHCP issues and talking w/ George, I have queried it again, for EXIT mode, and now I get…

                                Edit> I removed the output. It was misleading, because I had the PXE menu enabled. George and I are talking, and when looking at the SANBOOT option, it tries to boot into 0x80 instead of 0x81, which would be the second drive - which is the drive I am looking to boot from.

                                My SANBOOT output is…

                                #!ipxe
                                set fog-ip 10.1.10.42
                                set fog-webroot fog
                                set boot-url http://${fog-ip}/${fog-webroot}
                                sanboot --no-describe --drive 0x80
                                

                                The EXIT output is still the same, with the last line being exit.

                                  Immediately after calling the link I gave you earlier, check the apache error logs for entries from the moment prior.
                                  Web Interface -> FOG Configuration -> Log Viewer -> Apache Error

                                  Sort by newest first, be aware of the timestamps. Copy/paste what you find.

                                    What George and I were discussing regarded the saboot switches, in particular –drive 0x80. His thought was, whatever needs to be done, should be handling the assignment of this to 0x81, if I am trying to boot to /dev/sdb, which is on the second drive. These drives though, they are listed according to what the BIOS has listed? Or is there anyway to change what drive is mapped to 0x80?

                                      @Tom-Elliott the chainloading issue with the exit type in this thread is very similar to this thread:
                                      https://forums.fogproject.org/topic/8736/chainloading-failed

                                      Especially suspicious since it was worked on between 13 and 14 and is still having issues.
