Which 2 TB limitation ? EDD BIOS calls use 64-bit LBA and should not
have any practical limitation unless the BIOS implementation is flawed.

"For example, you cannot create 3TB or 4TB partition size (RAID based)

This is a DOS/MBR partition scheme limitation, not a BIOS limitation,
and irrelevant with GPT partition scheme.
how to get a > 3 TB partition for /dev/md2
Use GPT
yeah but the goal is to convert a existing RAID1/RAID10/RAID10 setup
with 4x2 TB drives to RAID1/RAID1/RAID1 with 2x4 Tb drives and so my
/boot won't work with GPT :-)
the two smaller machines are easier because of finally 2 TB drives - i
really think loudly about a USB stick for /boot with regular dd-images
and leave the existing RAID1 /boot ignored
