RAID 1 Rootfs on Rock 5b+

[bicebird]

Hi, picked up a Rock 5b+ as it looked like the exact right board hardware wise and the rk3588 is getting a reasonable amount of support and happy to see it's officially supported by Armbian.

 

Was able to build and flash the UEFI image and boot into the Fedora installer which would allow a RAID install but unfortunately it doesn't support either the PCIe bifurcation needed for both m.2 slots to work or the hardware acceleration for transcoding.

It looks like there's progress being made by Collabora so eventually mainline support should be good enough but for now I'm looking to use Armbian with the BSP kernel as able to boot into it with both drives being detected.

 

Had a look but couldn't seem to find any guides on how to install Armbian to two mirrored drives, could probably get by with one drive but it's going to be located at my parent's house 100 miles away so ideally would want to avoid a failed SSD needing an impromptu day's travel when I'm revising for exams!

Happy to learn the build process, manual copy file trees, edit fstab and boot parameters, etc but could do with being pointed in the right direction or at least know if it's a lost cause.

It looks like uboot supports mirrored boot disks, and Debian definitely does, so feels like it should be possible even if it's not a typical install.

 

Thanks!
