It has to do with the --metadata=imsm Intel Raid - I have heard it before ReaR cannot cope with it. Sorry, we do not have this kind of hardware so it is very difficult to help you.

I have RAID1 made by BIOS and I tried make some fix adding follow:

# If imsm is set, we can ignore RAID altogether
if grep -qw 'imsm' /proc/mdstat; then

on the beginning of the:

Because, I do not want to touch any on RAID through Linux, just make partitions and LVM if exists, but I did not finish it, because I have some another issues. Maybe, you can try this on your environment if you have similar situation.

I assume you also have the special Intel Matrix RAID hardware, cf.

Intel RST on Linux documentation:

Check if HW supports RST:
mdadm -–detail-platform
or less reliable:
lspci | grep "SATA RAID Controller"
