I set up a RAID 10 volume with 4x500GB drives. I need to increase the size by adding 2 more identical drives. Is it possible to do this without losing the data? If so, can I do it from Windows, or do I need to do it from BIOS? If from BIOS, when Windows restarts, does it see the extra space, or do I need to do something to then extend it?
Windows is installed on a RAID 1 volume on 2x 320GB drives on the same controller, so the RAID 10 volume is just data (SQL Server data files).
