Been messing with adding a raid-1 pair to my workstation. I have it now, but I'm looking at it and it shows half the size I expected.
I have two 3T drives. I formatted each to be a single partition type 'fd', "Linux raid autodetect".
Now, after I have it set up I get this:
What's up with that? Is there some limit on the size of a RAID partition?

$sudo fdisk -l /dev/sdb

Partition 1 does not start on physical sector boundary.
I've never used an array with drives this big before, and I don't see anything when I search on limits.
