Greetings.
I am in the process of installing 5.1 64 bit on a server. The server has 2 3ware cards: 9550SX 12 port, and a 8006 2 port, both SATA.
Any reason not to use 5.2? Will save a lot of updates, and perhaps some headaches.

Phil,
There are a couple of reasons, although they may make no sense. First, I did not want a multiple point of failure. If the boot loader is on the MBR of /dev/sda, and the os is on /dev/sdb, then you have a multiple point of failure. If either card dies, then I am hosed. It would be *similar* to running a RAID0 on the os. Not a good idea IMHO.
Also, if I wanted to replace the "data" drives in the future, I couldn't just unmount the partition and replace the drives. The boot loader would be gone as well.
A GRUB boot CD (or floppy) will allay the above concerns. Do an "info grub" to find out how to create one. Can also boot from install media to recover a lost GRUB.
I did not find an option during the install prep to re-locate grub to the MBR of /dev/sdb. I probably should try the text-based installer to see if there are more options.
It is there in the GUI installer - can't remember exactly where without going through the install, but something like an "Advanced" button on a configuration page toward the end of the process.
Heck, I may just remove the 9550 board until the initial os install is completed. That should accomplish what I am trying to achieve. Just seems like there should be a more elegant way of doing this.
I am installing 5.1 because I have the isos on hand. I was just going to let yum update me to 5.2...
That should work.
Thanks for your help,
OK
Phil
