Has anyone done a 0+1 SW RAID?
I am assembling an entry level server Intel s3000ah board, xeon 3220 2.4GHz, 8GB RAM and 4*160GB SATA II hdds. sda and sdb on one controller; sdc and sdd on an another controller.
I am thinking of configuring 2 disks (sda1+sdc1) in a RAID0 setup and then mirror this RAID device on the other 2 disks (sdb1+sdd1).
Has anyone done such a setup using sw raid in openSUSE?
Yes, I did, and it works great in general; I just configured the RAID0 on top of two RAID1 devices (because I _think_ it might be easier to deal with in case a disk goes havoc). As I'm a heavy multi-boot user, I tried to install a different version (e.g. openSUSE 11.1 32-bit vs 64-bit) and found out, that *none* of my md's or LV's on top of the md's were recognized :-( So, I deciced for me that this type of setup is probably too advanced at the moment; I now use the following configuration:
Manfred,
Please file a bug report on the installer failing to recognize raid setups. The installer is getting better, but obviously it still has holes in it. You can see where I left off with 11.1 and dmraid at:
Hmm, my situation may be different than yours as I don't use dmraid but plain vanilla soft md-raid{0,1}. FWIW, I just found out that using the raid10 mode instead of manually assembling a raid0 by combining two raid1's actually works and gets detected by the installer, so I'm OK now.
