Interesting! This is now working for save/restore full disk using the "stable" version with that boot parameter. I haven't tried restoring just one partition. Last time I assumed it wasn't working when I saw the message "excluding linux RAID partitions". Here is /proc/partitions for posterity. First is how it looks when Clonezilla first starts. Below is how it looks after choosing the repository.
I'll try to take another screenshot tomorrow, but isn't it clear from my post above, I showed you exactly where this happens in the source code ocs-functions
I was using 20220103-impish before. Today I tried 2.8.2-1 with that boot parameter you suggested and got exactly the same result. The RAID volume is not shown as a destination, and it shows "Excluding linux raid member partition..."
No, I just get a black screen on both IPMI remote console and the SOL (COM2). I see the regular UI on the HDMI display.
The nodmraid option was used to disable dmraid. Adding that back won't do any good, that's the opposite of what I need. In this case the kernel does see the RAID volume, but Clonezilla is specifically excluding it (as shown in the log). I'm looking for a Clonezilla setting to make it not exclude raid partitions.
The first step of getting this working was to direct GRUB's output to VGA. I did this by setting terminal_output vga_text in boot/grub/grub.cfg. Now I see the grub boot menu, but linux still sends its output to the GPU output. I've tried several kernel parameters like console=tty0 console=S1,115200n8 video=VGA-1:800x600@60me video=HDMI-1:d but this all seems to be ignored.
Steven, I'm not sure what you are suggesting I add. I'm asking how restore to an mdraid disk, because Clonezilla doesn't show it as a destination.
I figured it out. I had to recreate the USB stick using the ZIP file instead of ISO and format FAT32, and now when I boot to RAM, it lets me write to the USB stick.
