Keith> I'm running Fedora 8, and having suffered a recent hard disk Keith> failure, I want to set up a RAID1 array of two EIDE ATA 133 Keith> physical drives for my server.

Just make a single partition on each disk which spans the entire disk, then use mdadm to mirror those two partitions. Then use LVM to create the Physical Volume (PV) on the RAID1 mirror, then create your Logical Volumes (LVs) ontop of the PV. You can create as many LVs as you like.

So in total I Keith> would have my important data on three seperate physical drives. Good plan. Now automate it so you don't forget. :] Keith> I'm also making backups of my data to CD-R and DVD+R as well. I find the cost of CD-R media and DVD+R, as well as the issues with longevity, to be my biggest concerns. For those types of media, having a very robust and redundant easy to recover format would be key. Haven't seen it done yet, though it's been talked about. An Archive filesystem, not a general access one. Keith> I have the standard EIDE connectors on my Motherboard, which Keith> will be used for the backup ATA drive, and the DVD RW optical Keith> drive. All drives will use separate cables and work as master Keith> drives. This applies to the RAID1 array drives as well. Yup, this should work just fine.

Keith> Obviously I don't want to buy the wrong PCI EIDE/ATA controller Keith> card. It all depends on which modules FC8 has already compiled, but I suspect they have most of the standard ones already there. I've personally got a HighPoint HPT302 rocket RAID IDE controller in my system and it's worked well for quite a few years now. But in this day and age, why aren't you going SATA or have you already got the drives you're going to be using?

Keith> I'm running kernel-2.6.24.4-64.fc8 REally, it's all up to the Fedora Core people which modules they provide by default, so take a look in /lib/modules/... for what's there. I've also got a SIL3112 two/four port PCI Sata card and I've been happy with that one as well.
