*This Reply from / Antwort von / Antwoord van:* LLLActive@GMX.Net - 2011-06-09 - 01:25:41 +0200 Thanks for the replies Per, Andrew and David. @David: I actually have a Linux unsympathetic Gigabyte GA-K8N Ultra-9, with two onboard Raids; Sil 3114 (Silicon Image) and Nvidia. The Sil only works if it is set to Raid 0,1 or 10. The Nvidia allows the disks to be used as either Raid or singles. These Raids are also fakeraids. lspci 00:07.0 IDE interface: nVidia Corporation CK804 Serial ATA Controller (rev a3) 01:09.0 RAID bus controller: Silicon Image, Inc. SiI 3114 [SATALink/SATARaid] Serial ATA Controller (rev 02) So I thought the JMicron JMB 362/363 AHCI, with its advertised seperate BIOS and setup independent from OS, will be a proper Raid (see below). Some say they got it to work with a firmware driver at install time (F6 I think with openSuSE 11.4). @Per: I tried the methods with pata_jmicron and dmraid. They are loaded, but the so-called HW-Bios setup Raid 10 disk is not seen, only the seperate disks. I got it working with a Linux Raid. Would prefer a HW Raid though, the reason I got this one: http://www.amazon.com/Port-Sata-Raid-Controller-eSATA/dp/B003MEUT5W/ref=sr_1... It says: Raid Controller Leaf LC3124i Rev 6.0 *4 Port Sata II 300, PCI 32bit, 66Mhz* Silicon Image SIL3124-2, Sata II 300MB/s supports 4 internal HDD, as WD Green Caviar 4x2TB or seagate ST31500341AS 4x1.5TB or 4 external HDD using LC4CEB eSATA Adapter with own Bios (works independent from OS) supports optical drives (ATAPI) as CD/DVD/BlueRay burner supports Portmultiplier for up to 20 HDD supports Windows Sleep Modus and Wake On LAN (WON) Hot-Plug up to 7 Controller per Motherboard *Functions* Raid 5 (Parity) Auto Rebuild RAID 0 (Striping) RAID 1 (Mirroring) Raid 10 (Striping + Mirroring) Auto Rebuild CONCATENATION (makes from many HDD's large one) JBOD (single HDD) NON RAID (for additional HDD without RAID) BACKUP (HDD copy in bios) boots NT 4.0, Windows 2000, XP, 2003, Vista, Windows 7, 2000 2003 2008 Server, 32/64bit Mac OSX ab 10.4.9 (not bootable) bootable under Solaris bootable under BSD bootable under 32bit/64bit Linux Distribution 2.4.18.1 or later following distributions encludes already the driver: Archlinux, Centos, Debian, Frugalware, Gentoo, knoppix, RedHat, Suse, Ubuntu HDD's which are connected to the controller will be visible and you can install your favorite OS (operation system) on it. All well promised, but it is a fakeraid. @Andrew: Very true and correct what you say. I worked with 3Ware Escalade 4 Port cards the last 5 years without a hitch. I set up 2 Raid 5 servers with DRBD between them about 5 years ago. It is still running in my ex company. The Escalades are not cheap for private use, but I may wring myself eventually to get one. :-) http://www.amazon.com/3ware-9650SE-4LPML-256MB-Express-Controller/dp/B000K2I... I was thinking of using 2"3ware Escalade 9650SE-2LP" at 165Euro a piece, two mirrors striped by Linux Raid 0. Or is it better to mirror two stripes with Linux Raid 1? I have 2 PCIe X1 free as it is. http://www.amazon.de/3ware-Escalade-9650SE-2LP-Adapter-retail/dp/B000KBG4Y0/... I just have to convince my minister of finance that we need the investment. So, in the end, the JMicron is going back. I will have to invest into some real HW Raid. It is not a backup replacement, just some redundancy. Backups are made differential daily and weekly full. But my data backup now takes too long with my script using DAR. This brings me to another point - Anyone know of a reliable Mac-TimeMachine Like backup for Linux? I will start another thread for it. Thanks in the mean time. :-) Al *Original sent by / Original von / Oorspronklik van:* per@opensuse.org - Tue, 07 Jun 2011 18:37:25 +0200

Hi all,
I just got a JMicron JMB362/363 Fake RAID (SoftRAID). I searched the internet, and most are M$ drivers, and some mention Linux. None seem to have a real good idea how to get it to work properly. Does anyone know of a method to let opensuse read the hardware raid setup off of the controller, and not the separate drives.
I have: uname -a Linux Linux 2.6.37.6-0.5-desktop #1 SMP PREEMPT 2011-04-25 21:48:33 +0200 i686 athlon i386 GNU/Linux on an AMD Athlon 64 Processor 3200+ CPU and a GA-K8N Ultra-9 Mobo. There is in fact a pata_jmicron driver, which seems to intended for your controller - however, IIRC, these fake raid cards are often supported by dmraid. SOme quick googling indicates that dmraid has support for your controller. http://www.jmicron.com/Support_FAQ.html Q9
