Hi! Is there any possibility to install SUSE 10 on a System with two SATA drives combined to a RAID with a fake RAID chip resp. software RAID with BIOS support -- such as for example my SiliconImage 3112A which creates some special signature on the (MBR of?) the hard dirve(s?) called "Medley". On the ftp i see the required dmraid package, but can YaST at installation time make use of my "SATA fake RAID" ??? Alternatively, does somebody know any document which despribes the installation with at least the / prationon on the RAID but a /boot partition on a PATA drive? Searching net and mail archives didn't help me there ... ciao, nico.

Yes, it can (sort of). But the procedure is long and complicated and will probably change with SUSE Linux 10.1. I'll write the procedure down in a few days when I'm not overloaded with university work anymore.

That problem is not much easier, unfortunately. Regards, Carl-Daniel

Is there (or will there be) support for the fake-RAID detector/drivers like sata_nv and/or installing Linux RAID based on fake-RAID configuration? I have been googling my fingers off and have been unable to find any at-all-user-friendly way to install a current Linux distribution on a RAID 1+0 array of drives. I, personally, would be happy to use Linux software RAID BUT I have found it extremely difficult and problematic to set up. With hardware RAID (3ware, LSI, ...) I set up DRIVES in a RAID 1+0 or RAID 5 array and then treat it as one big drive when partitioning and installing. I believe, with newer kernels/mdadm/... that it is possible to create drive arrays (instead of partition arrays) BUT this does not seem to be supported by any current distributions installers. It would be great to be able to establish an array of drives in the fake-RAID BIOS and have the installer/grub/... detect that setup and use it for the basis for the Linux software RAID OR use the correct driver (eg sata_nv). Alternatively, if the installer allowed establishing two drives in RAID 0 (or 1+0) and then partitioning the resultant /dev/md1. I keep reading that /dev/md1 is just another block device but the installers do not seem to treat it as such. Any references to where this work is (or should be) done would be appreciated.

sata_nv is a hardware driver for the nvidia sata chipset, not for the fakeRAID part of the chipset. dmraid is a software package to layer an emulation for fakeRAID on top of existing hardware drivers.
I, personally, would be happy to use Linux software RAID BUT I have found it extremely difficult and problematic to set up.
With YaST2, setting up native Linux software RAID is done in 3 or 4 clicks during installation.
With hardware RAID (3ware, LSI, ...) I set up DRIVES in a RAID 1+0 or RAID 5 array and then treat it as one big drive when partitioning and installing.

Did you try YaST2?

Linux software RAID and fakeRAID are totally incompatible.

Should work with YaST2. Regards, Carl-Daniel

I tried installing using SuSE 10.0 RC1. It does NOT let me setup DRIVE arrays or 1+0 arrays of any kind (with however many clicks). I could set up either RAID 1 or RAID 0 partition arrays but it takes a few more than 3 or 4 clicks (which is OK if it is doable).
With hardware RAID (3ware, LSI, ...) I set up DRIVES in a RAID 1+0 or RAID 5 array and then treat it as one big drive when partitioning and installing.

I tried installing using SuSE 10.0 RC1 Is SuSE 10.0 RC1 installer using YaST2? If it is not using YaST2, how can I install using YaST2? Do I have to install SuSE on single drive, then use YaST2 to build a RAID 1+0 drive array then transfer the install to that drive then fix grub to boot from that drive etc.

OK. Scratch that hair-brained idea.

Should work with YaST2.
SuSE 10.0 RC1 install does NOT allow partitioning the resultant /dev/md... block device.
