Hi Tomasz,
at first: if you had 1TB drives before, dd'ed them to the new 3TB drives
and changed the partitioning scheme accordingly - that all looks OK.
The weird thing here is that 1TB disks never had 1024GiB, but 931GiB.
So the reshape has already happened to "the system's maximum".
I do suspect you have a 32bit system and mdadm is not the latest version?
No, the system was 64 bit from the very beginning; mdadm may not be the
latest one, but is far from being obsoletes, too (Debian Squeeze).
The issue is actually solved now.
What I had to do was:
mdadm /dev/md2 -f /dev/sdb3
mdadm /dev/md2 -r /dev/sdb3
# not necessarily 10 MB needs cleaning, but it's a small number...
dd if=/dev/zero of=/dev/sdb3 bs=1M count=10
mdadm /dev/md2 -a /dev/sdb3
# wait till it syncs, and do the same for /dev/sda3
reboot
If I did the same without dd if=/dev/zero, it somehow didn't want to
work and /dev/md2 was still only 1 TB big.
Unless I've messed up somewhere!
