Yes I did.

Was adviced to not use partitions in a lot of forums (ask ubuntu, stock
exchanged, linux sub reddits).
Looks like I did not do my research as thoughtful as I should have. I'm
sorry to bother the mailing list with my incompetence.
>Did you create the partition table before or after creating the RAID
array ?
I did so before I created the the RAID array.
>There have been reports lately which seem to indicate that something,
maybe the BIOS/UEFI firmware, "restores" the primary partition table
from an existing backup partition table at boot.
I did not enter or actively interact with the UEFI of my mainboard in
any way. I made sure to update and configure that before I installed the
OS.
Is there a list of the reports where I can check if my mainboard is
affected? Is there something I could do/contribute?
>Otherwise, I suggest that you erase all GPT metadata on each disk with
wipefs -a before re-creating the RAID array with --assume-clean. When
re-creating the array, make sure that sda, sdb and sdc are in the same
physical order as when you originally created the RAID array (check with
the serial numbers).
There is indeed data on the drives that I would like to access. As I did
not change the physical order of the drives, I'm going to give it a go.
Thank you for your help Pascal. Is there any recommendations from you,
where I should invest more research time on the topic?
