Hi,
I got two drives in RAID1 matrix, each one got 2 partitions, first
boot also in raid, containg grub and such
RAID or RAID array, not matrix.
My question is, what if I connect the new drive and it will appear
as /dev/sda, and the already working one will be /dev/sdb. Will it
overwrite it ?

The second question, Should I first create partitions partions on
this new drive ? What about GRUB ? I was struggling last time to
install it on both drives in MBR (do you have any proper procedure,
because GRUB2 it can boot from dmraid, but cannot install on
/dev/md0 for instance).
dmraid and mdraid are not the same thing.

That's after a couple of minutes of using google.
You could've found all of the bove yourself.
And above all:
% man mdadm
