Legacy boot on GPT has some requirements, but it works

So what ? Aren't you going to create a GPT partition table on your 4-TB
drives ? Else you won't be able to use the space beyond 2 TiB. (*)
A GPT partition table supports up to 128 partitions by default.
i won't have a choice as it looks like and so the easiest choice would
be migrate /boot completly to a USB-stick and simply ignore the current
/boot RAID1 which is just 482M small
since finally the new machines in the next step only support UEFI and
the uefi-system partition can't live on a RAID it would end there over
time anyways
the 4 machines are two pairs (homeoffice and office for two people)
cloned by remove two drives and rebuild the array on both so the
bbot-part is always identical and the stick on one can boot the other
so for now my last remaining question is "how would the command look for
"Then with just two drives you change the raid to raid-1"
(*) In the DOS/MBR partition scheme, Linux supports that a partition
ends beyond 2 TiB up to 4 TiB but this is a non standard trick and
probably not supported by usual partitioning tools
meh
