short answer: yes it will work fine.

longer answer: 200GB disk must be mounted before you can mount the 60GB

samba might mis-report size, but so what?
does df -h show that the combined total is 260GB?

lvm or evms would be a better way, but that would require quite a bit of
work since the disks are already up and have data.
