If /dev/md1 is made out of /dev/sda2 and /dev/sdb2, it will not work,
as those partitions will still be the same size as they were before...
I think it would be easier to just create new partitions /dev/sda3 and
/dev/sdb3, then create a new RAID1 /dev/md2, pvcreate it, and then use
vgextend to add /dev/md2 to the same volume group that already
contains /dev/md1.
Does that make sense to you?
Cheers,
Filipe
