Alle,
We currently have a CentOS 5.6 x86-64 server running using about 70G of a 500GB hardware raid partition. We'd like to install 6.0 alongside this installation in a dual boot configuration. We tried to install using the "Use Free Space" installation option, but the installer did not see the 475G of unused space. Is there any good way to do this, or is it even feasible?
Repartition first; if it's a hardware RAID, then in the firmware setup you should be able to break off part, and then make two partions: one of about 250M or so, for /boot, and the rest, larger, for the rest. Once you've done that, and the BIOS sees the partitions, you should be able to install.
I have a much longer discussion at http://24.5-cent.us/, in the article "Upgrading Linux" that I published a few years back.
