      @tom-elliott While I’m not sure what I can add to this thread, I do have to say I have several 4K sata drives that were purchased before I realized that ESXi didn’t support 4K drives (yet). If you need me to test anything (under linux or ms windows) I have the facilities to do so.

      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!

        @Abuelika Good to hear that you could make this work but I think this is a general issue that we’ll be seeing more and we need to figure this out. I’ve dug my head in the sector count swamp and would like to ask you to test something that I came up with.
        Hope you still have that 512 based image somewhere. Please edit the d1.partitions file again and make it look like this:

        label: gpt
label-id: EB5F756F-5E64-4990-8B9C-5F2826AFDEC2
device: /dev/nvme0n1
unit: sectors
first-lba: 5
last-lba: 61279312

/dev/nvme0n1p1 : start=           5, size=       51200, type=C12A7328-F81F-11D2-BA4B-00A0C93EC93B, uuid=F803B6B4-FAF1-4700-814F-4CC7B6AA693D, name="EFI System Partition"
/dev/nvme0n1p2 : start=       51205, size=    29095304, type=48465300-0000-11AA-AA11-00306543ECAC, uuid=2CA043B5-1BA4-4052-AC59-AA30F67E556D
/dev/nvme0n1p3 : start=    29146509, size=      158692, type=426F6F74-0000-11AA-AA11-00306543ECAC, uuid=989E4FD8-2721-4B58-A6B4-24E3334F1165, attrs="GUID:49"

        Make sure to get the values for *-lba, start and size right. I didn’t change the type or uuid values at all. Then do a deploy to the 4096 machine again.

        Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

          Hi @sebastian-roth

          okay. now I’m not in the office, tomorrow at 8:00 am I will do the test. I still have the image.

          I leave you the content of d1.partition of the new image made to imac with m2, in case you are interested.

          label: dos
label-id: 0x00000000
device: /dev/nvme0n1
unit: sectors

/dev/nvme0n1p1 : start=           2, size=    61279342, type=af

          root@fogserver:/images/MASTERMACOS2017_modelnou# ls -l

            @abuelika said in NEW iMac problems:

            label: dos

            What?!??!?! This doesn’t make any sense to me. Mac OS X is UEFI as far as I know, why would they use a legacy DOS/MBR partition layout? You said you transfered the system using TimeMachine? And it does boot properly? That’s crazy I reckon.

            Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

              Hi @sebastian-roth ,

              I have modified the file d1.particiones with the facilitated content.

              I have now unpacked another iMac with m2 and I’m capturing the image to review the d1.partitions and check the label to see if dos or gpt.

              This is the content I have modified from d1.partitions.

              label: gpt
label-id: EB5F756F-5E64-4990-8B9C-5F2826AFDEC2
device: /dev/nvme0n1
unit: sectors
first-lba: 5
last-lba: 61279312

/dev/nvme0n1p1 : start=           5, size=       51200, type=C12A7328-F81F-11D2-BA4B-00A0C93EC93B, uuid=F803B6B4-FAF1-4700-814F-4CC7B6AA693D, name="EFI System Partition"

                Hi @sebastian-roth

                I’ve unpacked an imac with M2 and I captured the image.
                The contents of the d1.partitions file:

                label: gpt

                the contents of the folder

                root@fogserver:/images/MACNOU-NET# ls -l
total 18645544
-rwxrwxrwx 1 root root       17920 sep 14 09:06 d1.mbr
-rwxrwxrwx 1 root root         249 sep 14 09:06 d1.original.uuids
-rwxrwxrwx 1 root root    14480899 sep 14 09:06 d1p1.img

-rwxrwxrwx 1 root root         610 sep 14 09:06 d1.partitions

                I think the problem of label: dos is that an empty disc was recovered with “TimeMachine” without an operating system.

                Now I am doing a capture of an iMac with M2 with operating system and restored with TimeMachine.

                  @Abuelika Thanks for trying and posting results. It’s good to know how the partition table on a fresh machine looks like and from the numbers it seems like I am not too far of it. Though we can’t directly compare the numbers I think as those were created by a someone else. But definitely good to know that my calculated numbers are kind of in that same range.

                  Please add isdebug=yes ismajordebug=1 again, try my suggested partition table again (first-lba: 5) and post a picture of the output on screen. So we see if it is the very same or a different error.

                  I compared the tables and the main difference from my point of view is that the new one you posted is starting at sector 6 whereas I calculated it to start at sector 5 (original 40 divided by eight (4096/512)). In an UEFI style system we should be able to move partitions as the boot loader doesn’t rely on sector counts. So you might also try this one (all partitions shifted by one sector):

                  label: gpt
label-id: EB5F756F-5E64-4990-8B9C-5F2826AFDEC2

                      @Abuelika I have looked into bringing up a VM with physical sector size of 4096 but still couldn’t make it work. Though I have the qemu/kvm command line options it doesn’t work yet. I hope to get this ready soon.

                          @Abuelika I think I found what’s wrong. Though I don’t know yet how to fix it. The problem is that we have d1.mbr based on 512 sector size as well as d1.partitions. So my changed d1.partitions didn’t do the trick. I am sure I can come up with something but still need a bit more time.
