SATA Raid 0 and Fedora Core 2

basix · 09-16-2004, 06:09 AM

Currently i have installed FC2 on a 10GB Seagate HDD. I am very happy with its performance. So I was wondering whether I should install it on a bigger harddrive. I am thinking of buying a 120GB Seagate SATA HDD. But I read around that FC2 has some problems with RAID. I just am going to use Raid Level 0 and wanted to know whether FC2 will support it out of the box. I havent even upgraded FC2's default 2.6.5 kernel.

Intel P4 2.8C GHz 800MHz FSB HT
Intel 865GBF motherboard(with the ICH5 controller)

Currently FC2 detects my hardware like this:

Code:

00:00.0 Host bridge: Intel Corp. 82865G/PE/P DRAM Controller/Host-Hub Interface (rev 02)
00:01.0 PCI bridge: Intel Corp. 82865G/PE/P PCI to AGP Controller (rev 02)
00:1d.0 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #1 (rev 02)
00:1d.1 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #2 (rev 02)
00:1d.2 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #3 (rev 02)
00:1d.3 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #4 (rev 02)
00:1e.0 PCI bridge: Intel Corp. 82801BA/CA/DB/EB/ER Hub interface to PCI Bridge (rev c2)
00:1f.0 ISA bridge: Intel Corp. 82801EB/ER (ICH5/ICH5R) LPC Bridge (rev 02)
00:1f.1 IDE interface: Intel Corp. 82801EB/ER (ICH5/ICH5R) Ultra ATA 100 Storage Controller (rev 02)
00:1f.2 IDE interface: Intel Corp. 82801EB (ICH5) Serial ATA 150 Storage Controller (rev 02)
00:1f.3 SMBus: Intel Corp. 82801EB/ER (ICH5/ICH5R) SMBus Controller (rev 02)
00:1f.5 Multimedia audio controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller (rev 02)
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV100 QY [Radeon 7000/VE]
02:01.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8029(AS)
02:02.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)

also, in /etc/sysconfig/hwconf, it shows the following info about my SATA controller:

Code:

class: IDE
bus: PCI
detached: 0
driver: ata_piix
desc: "Intel Corp.|82801EB (ICH5) Serial ATA 150 Storage Controller"
vendorId: 8086
deviceId: 24d1
subVendorId: 8086
subDeviceId: 4246
pciType: 1
pcidom:    0
pcibus:  0
pcidev: 1f
pcifn:  2

Basically, i just want to know whether SATA Raid will work out of the box with my system

. I just dont want to trash this install.

hello? people! does no one have any answer to my query?

I am also thinking about installing Fedora
since I would like to try it out. My greatest
reasons for installing it are...

SATA

I'm hopeful it will recognize my floppy drive, and CDR

I also want to try out the 2.6 kernel

does Fedora by any chance support hypertreading?

Fedora Core 2 currently does not support SATA RAID

FC2 supports RAID, it's just that there aren't any drivers for most of the onboard SATA controllers that support RAID currently. However, if you were to use a card that has support, you can run a SATA RAID array in FC2 just fine. 3Ware has always had great support in Redhat products, and their SATA cards work perfectly in FC2. I am currently running their 8006-2LP card in a couple of machines and it works great.

Here's the link to their cards if you're interested: http://www.3ware.com/products/serial_ata8000.asp

do u have any idea whether FC2 has support for intels onboard SATA controller. Or do you know where i could find out?

If its still in the experimental or unstable stage then I dont want to go in for it because my current hardware works perfectly with FC2 =D.

I'm not sure on the ICH5 chipset supporting RAID in FC2.. but if I had to guess, I'd say probably not. I'm sure it will work with 1 or 2 drives on their own, but I'm guessing that if you created a RAID array, FC2 would still read it as 2 different drives and your install wouldn't work. I know the Silicon Image SATA controllers are that way, and I seem to recall seeing others with Intel controllers that were getting that same problem when I was looking for one that would work (which is what lead me to 3Ware).

So again.. I'm not 100%, but I wouldn't hold my breath on RAID working out of the box.

Support for anything but 3Ware cards is sketchy at best without external drivers. See if Intel has drivers in development for your motherboard, or save yourself the headache and go pick up a 3Ware card.

ok, but what if i dont want raid? What if I just used the SATA drive as a normal non-raid harddrive?(I mean just a harddrive with SATA interface instead of the PATA) Would that be ok with FC2? Would it recognise my hardrive geometry? I heard some linux distros were having trouble recognising geometries over 120GBs...

SATA and SATA RAID are one in the same, I believe. I don't think there is a SATA card that comes without the RAID capability anymore.
