Well, all the drives with all their partitions are recognized by both knoppix and opensuse. Eg looking at /dev/disks/by-id directory.
The problem is that the raid set is not detected in openSUSE. The two drives which has the raid set is visible, and I can mount them. (I mount them only as read-only filesystems as I do not want to make any change and ruin the raid array)
I have one IDE drive (primary master in BIOS) with the OS (oS 11.2) and the two SATA drives connected to the SiI 3512 PCI card (in the BIOS this is a 'SiI mirrored set').
Knoppix assigns the drives as:
IDE primary master: /dev/sdc SATA 0: /dev/sda SATA 1: /dev/sdb
openSUSE assigns differently:
IDE primary master: /dev/sda SATA 0: /dev/sdb SATA 1: /dev/sdc
I don't know why the two systems assigns the drives differently and if it has to do anything with the recognition of the raid set.
Working with similar hardware and OS's today I thought I would try to figure out an answer to this. I couldn't, but nevertheless I suspect it's a driver order thing. I have to guess Knoppix's dmraid module is getting first crack at devices, so gets sda & sdb before the ide driver gets anything, which leaves it only sdc. The main differences between mine and yours: 1-you don't say which Knoppix you booted (6.4.4 here) 2-my 3512 is configured for SATA rather than RAID 3-I have only one HD attached to 3512 (on the eSATA port) In neither Knoppix nor 11.2 does the ata_piix module show up in lsmod output, while in 11.2 sata_sil is missing only from Knoppix, which tells me that for 11.2 at least ata_piix has first dibs on the HDs and why 11.2's IDE gets sda.
