There won't be any issue in doing this. The installer just tries to make things easier by creating one big volume group. I'd say that in some ways seperating the two disks in this case would actually be better. :) With both drives in one big volume group, failure of one drive will (most likely) cause both the OS and data to be lost. Seperating them will mean that if your OS drive fails you can replace the dead drive, reinstall CentOS (or restore from a backup), and your data will be accessible again. Of course you would still have to create regular backups, or you would still be in a very unhappy situation if the data drive fails but it would still save you a lot of headache in the event that you encounter a situation in which only the OS drive fails. :) Regards Hamzah -- M.
