Hi Roger,
You're right, but I did change the partitions on ONLY one of the
mirror disks, the other one hasn't been touched (/I believe/) except
I stopped the array and rebooted. This one still has the MD type from
what I see, but the mdadm doesn't seem to find any superblocks in
there...
I copied this one over to another HDD, where I did try to
unsuccessfully recover it, but I'm not confident I did the recovery
correctly.
This is very very similar to the case Neil mentioned in his article
here: https://neil.brown.name/blog/20120615073245
Is anyone able to investigate my issue please?
Thank you guys!

Wild guess based on many past experience with "lost" data/disks.
If the partition table moved because of some mistake
(someone/something repartitioned the disks and moved the start of the
partition) then after the reboot the array would be "missing" as the
header is not where it expects it to be. If the array was on
unpartitioned disks and the disks later got partitioned that can also
hide the disk. Either of these will appear to cause the array to not
be found. Or if the disk was partitioned but the partition was remove
that will also cause the array to be missing.

Sorry for the delay here, I was away for almost a month.
I've attached the outputs as suggested, please let me know if there's
anything else that might be needed.
Really appreciate your help!

Take a look, post the requested info, and we'll see what we can
do.
