So this is what I will do :-) The RAID-Howto as well as the LVM howto are however woefully out of date. I will try to work with the linux-raid website's info.
Basically I plan to do: - Put the boot partition on a RAID1 - Put the root partition on another RAID1 (I thought about putting the root filesystem into my LVM setup, too -- it is REALLY annoying if the root partition get's to small), but it seems safer to let root be an own partition. Or are there any different opinions here? I'm very interested in hearing experiences... - Build a RAID1 partition for the rest of the system (will be a LVM2 container) - Build a last RAID0 partition for scratch data (/tmp, /var/tmp, /usr/portage, scratch data). Any comments? Obviously insane? :-) Don't think so. - Wolfgang
