I installed PVE 8.* to SSD in ODD Slot (which is recognized by onboard Controller as Slot 4 after adding 3 drive into Bays) and would like to chainload from mSD to this SDD PVE Installation. As seems there is no other possibility then grub and chainload, at least I did not find that people are using something else. There are a lot of topic/blogs on this Problem, but I am unable to get it working on my side.
When there are no other drives inserted into Bays, the PVE will boot normaly from ODD SSD. While Installing PVE i selected ext4 File system nothing special.
When I insert other drives into Bays, and insert mSD to mSD Slot, i see shortly Grub and it goes to "grub shell". It does not boot PVE from ODD.
When inside grub shell I type ls, I see drives, but no partitions from hd4 (which should be SDD in ODD).
This is how I prepared mSD with grub:
After that I power off the server, inserted three drives in bay, inserted mSD into slot. And started server again. After that I see only grub shell like below:
Any hint is welcome, as I am not sure what to do else.
