Having finally accepted that my old desktop is functionally dead (erratic hard disk on ancient motherboard) I am getting a new desktop base unit, and hope to set it up as a PCLinuxOS only machine with two SATA II drives in a RAID 1 configuration. I have searched the forum under 'RAID', but haven't seen anything relating to this kind of new installation. If anyone has experience of doing this from a Live CD install, I'd be glad to take advice.
Strictly my own personal view, but my advise would be, "Don't bother."
With the mylivecd application you can make an up to date remaster of your installation, as often as you wish. With it, you can reinstall your installation with all your personal choice of applications, and personal tweaks in your /home/<you> directory already in place, in a matter of minutes, any time a problem you can't readily fix crops up. You can also use it to install to other computers as well. If you wish to have a separate /home partition, you can use the mylivecd application to just backup the / partition with all your installed apps.
Setting up a RAID just adds a layer of complexity to your installation, giving one more thing that can go wrong, and making it that much harder to recover, if something actually does go wrong. We don't encourage the use of RAIDs or LVMs for personal desktop machines, and don't officially support either.
Better use of the second drive would be for more storage capacity, or selective backups.
