Correct!
 afaics you meet this problem in several situations:
A) a single disk, larger than 2.2 TB
B) several smaller disk, forming a RAID with a combined total size
larger than 2.2 TB
C) Combination of A) and B)

I got a couple of 3TB disks and wanted to make a "raid 1+0"
Not shure i can stuff more than the planned four disks...
But if so, it would only solve the booting issue

Anyway, i understand that it is still "an issue" in general.
