Hi all,

I tried to convert a new Debian Image with mender-convert. I used this tutorial "
Convert a Mender Debian image"

fdisk -l
Disk /dev/sdb: 58.7 GiB, 63023063040 bytes, 123091920 sectors
Disk model: Generic
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: gpt
Disk identifier: 426D7739-915A-4024-B48B-A9734A997101

Device       Start      End  Sectors  Size Type
/dev/sdb1     2048   391167   389120  190M EFI System
/dev/sdb2   391168  1368063   976896  477M Linux filesystem
/dev/sdb3  1368064 13086719 11718656  5.6G Linux filesystem

My build stepps:

  • mkdir input
  • cd input
  • dd if=/dev/sdb of=debian.img bs=1M conv=fdatasync
  • cd …
  • ./scripts/bootstrap-rootfs-overlay-hosted-server.sh --output-dir ${PWD}/rootfs_overlay_demo --tenant-token ${MENDERTOKEN}
  • MENDER_ARTIFACT_NAME=release-1 ./docker-mender-convert --disk-image input/debain.img --config configs/generic_x86-64_hdd_config --overlay rootfs_overlay_demo/

But I get this error message:

Can someone please tell me what else I need to adjust?

Thanx

Hi @Dirk welcome to Mender hub.

My guess is that this is due to the extra partition in your input image. What are the two Linux filesystems used for here? The mender-convert probe functions may need to be modified to support this partition layout.

Hi @drewmoseley ,

I I followed this schema:

  • /boot/efi - size 200MB
  • / (root partition) - size ~6GB

Don’t I have to create an extra partition for /boot?

@drewmoseley Yes, you are right. I created the image only with a Linux partition and now it ran through. Thanks

Great. Thanks for reporting back.
