Hi, Originally I posted this in comp.os.linux.setup: http://groups.google.co.hu/group/comp.os.linux.setup/browse_thread/thread/423e609a98ce3664/089c9231b9cef998?hl=hu#089c9231b9cef998 Before posting I STFW quite extensively, but found no solution Since I got no answer, and I think this is related to dmraid, I multipost it here as well. Sorry for the inconvenience... I have problems with dmraid recognizing vendor proprietary JBOD array. Am I right that dmraid should be able to create mapper devices for the already active array? Thanks, András ---------------- The original post ---------------- Hi, I have a Debian sarge installation based on 2005-08-15 testing version. (I only managed to install Debian with this version, but custom steps were needed in order to make it bootable and available.) There are two physical disks in a JBOD (Span) RAID array created by SATA VIA VT6421. In the array there are three partitions, XP, Linux and Win2003, in this order. I can mount the first partition. Now I'd like to mount the third, but the ntfs module complains about illegal structure. This is ok, since the partition is on the 2nd physical drive, and there is no partition table because of the JBOD setting. I tried to make it available via a virtual device provided by dmraid, as instruced by the Linux SATA RAID FAQ: http://linux-ata.org/faq-sata-raid.html#dmraid I have two questions: Q1: How can I mount the 3rd partition for the current system? Q2: I'm about to reinstall the same structure but into a RAID0 array instead. I'd like to use Windows and Linux, and also have the advantage of striping. How can I make the installer to see the array? (dmraid does not come with the installer. All the installers I tried saw only two physical disks.) Please find some console output at the end of the post. Thanks, András ---------------------------------------------------------------------- # lspci -n 0000:00:00.0 0600: 8086:2590 (rev 03) 0000:00:01.0 0604: 8086:2591 (rev 03) 0000:00:1b.0 0403: 8086:2668 (rev 04) 0000:00:1c.0 0604: 8086:2660 (rev 04) 0000:00:1d.0 0c03: 8086:2658 (rev 04) 0000:00:1d.1 0c03: 8086:2659 (rev 04) 0000:00:1d.2 0c03: 8086:265a (rev 04) 0000:00:1d.3 0c03: 8086:265b (rev 04) 0000:00:1d.7 0c03: 8086:265c (rev 04) 0000:00:1e.0 0604: 8086:2448 (rev d4) 0000:00:1f.0 0601: 8086:2641 (rev 04) 0000:00:1f.1 0101: 8086:266f (rev 04) 0000:00:1f.3 0c05: 8086:266a (rev 04) 0000:01:03.0 0280: 8086:4220 (rev 05) 0000:01:04.0 0c00: 104c:8023 0000:01:05.0 0200: 10ec:8169 (rev 10) 0000:01:07.0 0104: 1106:3249 (rev 50) 0000:03:00.0 0300: 10de:00c8 (rev a2) ---------------------------------------------------------------------- # lspci 0000:00:00.0 Host bridge: Intel Corporation Mobile 915GM/PM/GMS/910GML Express Processor to DRAM Controller (rev 03) 0000:00:01.0 PCI bridge: Intel Corporation Mobile 915GM/PM Express PCI Express Root Port (rev 03) 0000:00:1b.0 0403: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 04) 0000:00:1c.0 PCI bridge: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI Express Port 1 (rev 04) 0000:00:1d.0 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) USB UHCI #1 (rev 04) 0000:00:1d.1 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) USB UHCI #2 (rev 04) 0000:00:1d.2 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) USB UHCI #3 (rev 04) 0000:00:1d.3 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) USB UHCI #4 (rev 04) 0000:00:1d.7 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) USB2 EHCI Controller (rev 04) 0000:00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev d4) 0000:00:1f.0 ISA bridge: Intel Corporation 82801FBM (ICH6M) LPC Interface Bridge (rev 04) 0000:00:1f.1 IDE interface: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) IDE Controller (rev 04) 0000:00:1f.3 SMBus: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) SMBus Controller (rev 04) 0000:01:03.0 Network controller: Intel Corporation PRO/Wireless 2200BG (rev 05) 0000:01:04.0 FireWire (IEEE 1394): Texas Instruments TSB43AB22/A IEEE-1394a-2000 Controller (PHY/Link) 0000:01:05.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
