      Hello,

      In 2020, with my FOG 1.5.7 / Debian 8, I’ve captured an Ubuntu 20.04 workstation (single disk resizable).

      In June 2021, I upgraded my FOG to 1.5.9 / Debian 10. Since, my image is still working when I deploy it.

      Today, in this image, I need to modify the content of a configuration file and do system updates (security updates, no change of the Ubuntu version).
      So I deploy my image on my test workstation, I do my changes, I create a new single disk resizable image on my FOG (because I want to keep my working image), I capture my image “in this new slot”, I deploy it on my test workstation.

      At the end of the deployment, FOG prints Resizing extfs volume (/dev/sda5)…………Done but the system partition isn’t expanded (its size is 130 Go on a 256 Go SSD).

      I ran fsck -fv from a live CD before retrying a new capture and deployment: fsck sees no errors, but the expand still fails.

      I upgraded init.xz and init_32.xz to 20220204 (https://fogproject.org/inits/init.xz) before retrying a new capture and deployment: expand still fails.
      I use 5.10.71 bzImage.

      I tried zerofree before a new capture and deployment: still fails.

      I have read a few threads in this forum, no help.

      Reinstall my test workstation from scratch to capture a fresh image would be too expensive in time (several bullshit business softwares, tricky configuration,…).

      Differences:

      • d1p2.img (the extended partition) is absent in V1.
      • fixed_size_partitions content is different.
      • in minimum.partitions, the extended partition is smaller in V2
      • in partitions, the extended and ext4 partitions are smaller

      I tried to copy all files except “d1p5.ebr” and “d1p5.img” from myImageV1 to myImageV2 before retrying deployment of myImageV2: the expand still fails.

      I have no idea how to solve my problem.

      Any idea? 🙂

        @glucas Sorry for the delay. We have been pretty busy with other stuff and topics.

        Do I get this right. With FOG 1.5.7 this exact same image was properly expanded to a larger disk?

        From what I see so far the extended partition is still expanded but not sda5 on deployment. Right?

        Still need more time to further investigate this-

        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)

        Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

          I did a few more tests.

          It seems that the version of init.xz is important. So, I tried to get its version number. To do that, I use: 7z x init.xz 1>/dev/null && /sbin/dumpe2fs init 2>/dev/null | grep -E '(UUID|created)'

          On my FOG 1.5.7:

          Filesystem UUID:          4bf29812-3f33-4d94-9787-76f18704df76
Filesystem created:       Mon Jul 15 19:13:43 2019

          On my FOG 1.5.9:

          Filesystem UUID:          1c9acfae-b3e6-4506-8ccc-4ffbff7bdfce
Filesystem created:       Sun Sep  6 10:12:57 2020

          On my FOG 1.5.9 after upgrading init.xz to version 20220204 (see my previous post): not a filesystem, but the more recent files in the archive are dated Feb 4 2022.
          `

          With FOG 1.5.7 this exact same image was properly expanded to a larger disk?

          About myImageV1 (version 1) created in 2020 on my FOG 1.5.7 with init.xz from 2019:
          Deployment with FOG 1.5.7: properly expanded ;
          Deployment with FOG 1.5.9 + init.xz from 2020: properly expanded ;
          deployment with FOG 1.5.9 + init.xz from 2022-02-04: NOT expanded.

          For all my tests (between 2020 and today), I always used the same test workstation (with 256G SSD).

          So, yes, the exact same image was (and is) properly expanded to a larger disk (unless the version of init.xz is 2022-02-04).

          About myImageV2 (version 2) created in Feb 2022 on my FOG 1.5.9 with init.xz from 2020:
          Deployment with FOG 1.5.9 + init.xz from 2020: NOT expanded ;
          Deployment with FOG 1.5.9 + init.xz from 2022-02-04: NOT expanded.

          Reminder: my steps to create myImageV2:

          1. I deploy myImageV1 on my test workstation ;
          2. I modify the content of a configuration file and I do system updates (security updates, no change of the Ubuntu version) ;
          3. I capture in myImageV2.

          .

          From what I see so far the extended partition is still expanded but not sda5 on deployment. Right?

          Right, except with init.xz 2022-02-04.

            New tests:

            1. I deploy myImageV1 on my test workstation with FOG 1.5.9 + init.xz from 2020 (see my previous post)
            2. Boot my test workstation on a Ubuntu LiveUSB to change logical partition (sda2) into primary one with fixparts + resize partition with gparted + fsck + grub-install
            3. Modify what I want on the system (do system updates, modify the content of a configuration file)
            4. Capture from my test workstation to myImageV2 (with FOG 1.5.9 + init.xz from 2020)
            5. Deploy my new myImageV2 to my test workstation (with FOG 1.5.9 + init.xz from 2020)
            6. The partition is properly expanded

            .
            AMO, the logical partition (sda2) confuses / puzzles partclone (or an another piece of software).
