We have some improvements about RAID in testing Clonezilla. Not sure it it works or not for this case. Please give testing Clonezilla live >= 3.3.2-26 a try: https://clonezilla.org/downloads.php
Thanks for your feedback. "clones of bootable drives are not themselves bootable" -> What did you mean by this? Could you please share more? Like what's the OS you are cloning? What's the error message when you boot the restore OS? Thanks.
So are you able to boot your source machine and the OS runs well?
In that case, there is a workaround for you. You can manually mount it as image repo by: Enter command line promot sudo mount /dev/mmcblk1 /home/partimg exit You will back to the main TUI of Clonezilla live, and go on as usual. It won't ask the image repository.
So you are using unicast? In that case, it's one time shot... Are you able to use multicast/broadcast? With that, the y1 will make the PXE client to boot from PXE and the server will keep providing multicast/broadcast service.
It would be better to share the image so that I are on the same page.
Try to choose the option "fsck-y" when saving: https://clonezilla.org//clonezilla-live/doc/01_Save_disk_image/images/ocs-08-1-sdb1-as-img-repo-fs-check.png
So what you want is to save your /dev/mmcblk1 device which has no any partition table? The Clonezilla TUI normally only lists the device which has a partition. If you really want to save a block device which has no partition table, you can try to enter expert mode, and choose to list all the disks and partitions, and it might work.
