Seeing as no-one else has commented - you don't happen to have a spare disk
by any chance? In that case you simply create a new 6TB partition on your new
disk, and do a replace. You can then rinse and repeat with the disk you've
just freed.
Otherwise, what I think you do is ... SHUT DOWN THE ARRAY. I *think* you can
increase the partition size by deleting the old 3TB partition then just
creating a new one starting in exactly the same place. Do it on one disk,
test it by restarting the array. If it works, rinse and repeat on the second
disk.
You now have a 3TB array on 2 6TB partitions. You should be able to do an
"mdadm --grow" on the array - no need to specify the size as it should
default to 6TB - to make a 6TB array. There are reports that might fail - a
reboot should fix that - and you can now grow your filesystem to use the
whole array.

that's exactly what i did
no lost data
