Unable to retain existing partition during autoinstall

[Elliott Barrere]

I am attempting to auto-install over a system provisioned with Red Hat Enterprise Linux. The system has a partition, /dev/sda3, with a logical volume containing /home that I would like to retain.

I have tried all sorts of storage configurations but I cannot find one that works.

Here is my latest example:

  storage:
    grub:
      reorder_uefi: False
    config:
      # EFI/BIOS and boot partitions
      - {type: disk, id: disk0, grub_device: true, ptable: gpt, preserve: false, }
      - {type: partition, id: bios-boot, device: disk0, size: 1G, flag: bios_grub, number: 1, preserve: false, }

      # root vol
      - {type: partition, id: vg-part, device: disk0, size: 33713M, wipe: superblock, flag: '', number: 2, preserve: false, }
      - {type: dm_crypt, id: dm_crypt-0, volume: vg-part, key: temporarypassword, preserve: false, }
      - {type: lvm_volgroup, id: root-vg, name: ubuntu-vg, devices: [dm_crypt-0], preserve: false, }
      - {type: lvm_partition, id: root-lv, name: root, volgroup: root-vg, size: 15G, preserve: false, }
      - {type: format, id: root-fs, fstype: xfs, volume: root-lv, preserve: false, }
      - {type: mount, id: root-mount, device: root-fs, path: /, }

      # data vol
      - {type: partition, id: data-vg-part, device: disk0, size: 750G, flag: '', number: 3, preserve: true, }
      - {type: lvm_volgroup, id: data-vg, name: data_rhel9test, devices: [data-vg-part], preserve: true, }
      - {type: lvm_partition, id: home-lv, name: home, volgroup: data-vg, size: 650G, preserve: true, }
      - {type: format, id: home-fs, fstype: xfs, volume: home-lv, preserve: true, }
      - {type: mount, id: home-mount, device: home-fs, path: /home, }
