Fedora Installation :: Intel ICH RAID In BIOS - Use Or Not?
Jan 5, 2010
As I understand, Fedora 12 sets up Intel ICH (when set in BIOS) as mdraid instead of dmraid.I would like to setup my 2 SATA hard drives so ultimately my /boot partition is RAID1, my / (ROOT) partition is RAID 1, and my swap is either RAID0, or fstab referencing 2 partitions on 2 of the drives, both set with pri=0 (which supposedly is equivalent to striping of RAID0, performance wise).
Assuming Fedora 12 uses mdraid for my configuration in either instance, am I better of enabling, or disabling the RAID mode in the BIOS? This system is strictly Fedora--no dual booting, no Windows. Any performance gains; reliability benefits between either scenario?It's a Intel P35 motherboard with ICH9R. Storage configuration is either "AHCI" or "RAID"
I ran into some strange issues with dropping drives with the RAID set on in BIOS. When it was set, that gave me two md devices of md126 (RAID0, swap) and 127 (RAID1 split between / and /boot). I think I had md126p1 for the SWAP, and md127p1 for /boot and md127p2 for / Within purely software, i have:
/dev/sda1 RAID
/dev/sda2 swap
/dev/sda3 RAID
[code]...
I suppose unless the BIOS enabled RAID is supposed to be faster, I'll stick with a purely software route and keep the BIOS set to AHCI.

I'm attempting to install F13 on a server that has a 2-disk RAID setup in the BIOS. When I get to the screen where I select what drive to install on, there are no drives listed. The hard drives were completely formatted before starting the 13 installation. Do I need to put something on them before Fedora will install?

I have recently installed Ubuntu 10.04.1 lts server on my Intel "fakeraid" (software raid) (2x250 sata).To test my RAID 1 I turned off one HD and start the system.The first screen (Intel software screen) show Status = Degraded, but the system starts normally with just one HD.Then I turned off the system and turned on the HD again, so the first screen (Intel software screen) shows Status = Rebuild. If I enter in the software raid panel the folowing message is showed: "Volumes with "Rebuild" status will be rebuilt within the operating system"The system starts normally... but this message status stays permanently even I restart the system again

Installing new Intel server S5000VSA (Sapello) motherboard with RAID 1. Downloaded F10 32 bit DVD and run install. Everything works fine and select Samba and all that. Install completes but on reboot get a blank screen.
I know with Windows one has to load the RAID driver off the Intel driver CD, so guess that is the problem. But how do I do this in Fedora? Question: How do I get to select the Intel RAID driver in the install process? There does not seem to be any place to stop and make this selection. I tried selecting the Red Hat and Suze installs on the Intel configuration assistant but it then reboots and that is it. In Windows it would ask to insert the Intel driver CD but that does not happen. So I am stuck. I loaded Fedora some 3 year ago and like it but then it was not on a RAID setup. I created a VMWare install on my desktop and did the same install options and it works. So the DVD seems fine.

I've played with Ubuntu, and a linux evangelist at work has talked me into trying it again.I happened to be wiping my machine, so my plan was to have Windows 7 and Ubuntu on one hard drive (100GB for Ubuntu, the rest for Windows), and the second hard drive for downloads, TV, films, etc.First I installed Windows, then I torrented the x64 Ubuntu 10.04 live CD iso, and burned it to a DVD. I booted from it and installed on the second partition, but I then found when I booted back into windows that my second hard drive wasn't there any more.
It didnt take long to work out that Ubuntu had installed using the second hard drive as a mirror. This is very confusing to me, as I've disabled RAID in my BIOS. I booted from the Ubuntu CD again and looked for options about this but didn't find any. Eventually out of frustration I just unplugged the second hard drive, but now when I boot from the CD to install, no hard drives show up for me to install to.

I just assembled a PC
amd x3 64bit
4 GB RAM
ATI HD4350
Asrock MB
2 HD WD 320 put into RAID 0.
To make this configuration, I have not enabled the raid from bios (since Ubuntu gave me problems) but I followed this guide [URL] (Official guides) to configure software RAID offered by ubuntu. Everything went ok and it works perfectly but when released the 10.04 and the system asks me to update, you think there will be some problem or leaving will be updated throughout unchanged RAID configuration?

This question is going to flag me as being a bit green to Ubuntu, but I must confess that in 15+ years in I.T., I have never had such a hard time understanding the partitioning scheme. Here's where I'm at.
I installed from the 9.10 live CD and selected the option to use the entire disk. The system has an Intel raid controller built in to the motherboard and two 80GB hard drives in a mirrored configuration. The system has previously been used with both XP and FreeBSD and never had an issue with partitioning or, more importantly, getting the boot manager to work.
So the live CD partitioned my hard drives, installed all the software and mount points, and claims that everything is finished. When I reboot, no boot device is found. If I then boot again from the live CD and select the option to boot from the hard disk, it does and I am in fact typing this message from the system. However, nothing I can do will make the thing boot without the bloody CD.
I've spent hours trying to figure out how to make grub work, or how to fix the MBR but no luck. The drives don't show up as /dev/hda or as anything logical that I can discern, so I can't even construct a workable install-grub command. Doing a df gives me this:
[Code]...
which is not very informative, is it? FreeBSD was never such a pain to make boot.Frankly, I'm not very impressed that a clean install (non dual boot) on such a standard hardware configuration could be so difficult to make the boot loader work. Documentation on this subject is voluminous but very shabby. I have searched and searched and I cannot find any mention of hardware mirrored IDE or SATA drives, nor what dev they would show up as. Very frustrating. Every tutorial I've read on installing grub2 or grub just doesn't work, usually because the dev is not right.
Can anyone shed some light on this bizarre behavior and perhaps offer some advice that will allow me to boot this system without the use of a live CD?

I have a system with: - 1 SSD "boot" drive - 3 HDDs in RAID 5. I created my RAID 5 set in BIOS - P6X58D motherboard/Intel Software RAID - Looks and works fine in Windows 7 (Ultimate) 64-bit. I installed Ubuntu 10.04 using wubi - both Windows 7 and Ubuntu systems are on the SSD THE PROBLEM Ubuntu does not appear to recognize my RAID 5 set - when it loads I see a "/dev/sd_ 10 failed" error (sd_=sda, sdb or sdc) along with "no such file or directory" - I can see my 3 HDDs in 'Disk Utility,' but the space/partition information is incorrect - I reinstalled all packages related to RAID (dmraid, etc.)

I set up an array of 2 hhd in raid0 using intel ICH7R, and i have a win7 installed on it. I'd like to have a dual boot with karmic, too. I googled a little bit and i found that it's not so easy as i thought. Are there anyone who's experiencing my same situation?

I recently bought a new system that has an Intel Matrix Storage Manager "RAID controller" (ICH10R/DO) on it. I'm a bit baffled over what this really is. I see at [URL] that this controller is supported by the Linux dmraid and mdadm commands and supported in the 2.6 kernel version for quite a while. This looks as though it is some sort of convergence of a brain-dead hardware chipset that requires software installed in the OS to manage it. Kind of reminds me of the wimpy Windows modems of the past. How I deployed. I set up two Seagate ST31500541AS disks as a mirrored pair in the hardware controller interface (CTL-I setup after POST).
I installed Fedora 12 in the usual fashion, though was confusing considering I expected a single "RAID device" to be seen by Anaconda. I went ahead and set up the two native /dev/sda and /dev/sdb as a mirrored RAID device on installation (mdadm under the cover). Recently, Palimpsest is insisting that I have a disk problem with "Disk has many bad sectors" error on /dev/sdb. When I run "dmraid -s" it tells me that the meta device is OK and I see no hardware errors in the messages log. I'm not having kernel panics as others seem to have had on RHEL 5.x.

1st I am relatively new to linux (but not to *nix). I have 4 disks assembled in the following intel ahci bios fake raid arrays:
2x320GB RAID1 - used for operating systems md126
2x1TB RAID1 - used for data md125
I have used the raid of size 320GB to install my operating system and the second raid I didn't even select during the installation of Fedora 14. After successful partitioning and installation of Fedora, I tried to make the second array available, it was possible to make it visible in linux with mdadm --assembe --scan , after that I created one maximum size partition and 1 maximum size ext4 filesystem in it. Mounted, and used it. After restart - a few I/O errors during boot regarding md125 + inability to mount the filesystem on it and dropped into repair shell. I commented the filesystem in fstab and it booted. To my surprise, the array was marked as "auto read only":
[Code]...
and the partition in it was not available as device special file in /dev:

I have an MSI 845E Max Motherboard. I just purchased the computer USED. I have no manual and from all accounts of the online manual, this MB is doing the impossible.Connected to this MB are 2 WD 60GB hard drives. Bother are recognized in the bios. When booting from the live CD, and running the disk utility I can plainly see that there are the 2 drives and one striped array (using both of those drives).There is no settings in BIOS for any array. If I remove 1 of the drives, the disk utility sees only 1 drive but still sees an array. I can find no way to eliminate, recreate, oe manipulate this array in any way.To make matters worse, I attempted to install an older FREEBSD, using it it saw both drives (no raid). Using their Disk utility I re-partitioned both drives and continued the install. Unfortunately the version I had was an older one and it could not complete the FTP install (And I would rather have Ubuntu anyways). Though through this action I believe that I have destroyed the integetery of the raid and if it is to be used it needs to be fixed.So.. how do I fix something that my BIOS is not supposed to be capable of doing? Has anyone else experienced this issue.

I'm helping my brother setup a server he has. The server has a 3Ware 9690SA Hardware RAID card, and it has 4 x 2Tb 5400 RPM Samsung Harddrives. When I boot into the 3Ware BIOS, it recognizes all 4 drives, no problem. What he wants to do is install them in RAID 10 for a 4 Tb mirrored volume for performance and redundancy. When I try to create a RAID array with the 4 drives, and set it to use RAID 10, it only allows me to utilize 2079 Gb (1/4 x 8 Tb), which is half of what I would expect for this RAID config.
Assuming I go ahead and allow it to build the array with this volume, we can go on to install Fedora 14 with no issue, but still only 2 Tb are available. This is our first time setting up a RAID array like this, I've also tried enabling Auto-carving to insure that I have support for physical volumes larger than 2 Tb, but to no avail. With the version of Linux we're running, and the RAID card he's got, it should support greater than 2 Tb PVs either way though.

I changed something in the BIOS which causes a kernel panic, if my card is installed (Ultra ATA/133 PCI-to-ATA Host Controller). I had it working fine til a month ago, when I installed some Linux on a HD on that card. That booted fine too, and I did some disk switching. Still all was well, but yesterday I tried to boot XP (2nd IDE master)(GRUB is Ubuntu/2nd IDE slave), and XP wouldn't load. I clicked here, and clicked there, and now XP and Ubuntu boot, ONLY if the RAIDbus card is Out. Put the card in, and I get a kernel panic/lockup. This HAS to be a BIOS function - nothing is different on the disks, including GRUB menu.

I'm completely new to Fedora, though not to Linux (I'm switching from Ubuntu 9.10, now) and am having a few problems getting it installed. I followed the installation instructions, torrented the i386 DVD image, and put it on a 4gb USB drive using UNetbootin.
This is where my problems started. I restarted the computer, figured out which F key I needed to press to select the boot source, and then there wasn't a USB boot option. I've looked all over the place (using Google) and can't find out how to get the BIOS to have a USB option there-- I'm using a Toshiba Satellite A10, and that doesn't come with the USB boot option.
Now I'm trying to either figure out how to add the USB boot option or find another way to install. Burning a DVD (or CDs) doesn't work, as I don't have the resources to do so. I've seen somewhere that there's a way to install from a hard drive partition, but no instructions on how to do so (if someone could point me to a way to do that, it seems to be my best option right now-- if it even exists).

I have a server with an Intel S875WP1-E motherboard and 4 HD of 400Gb each. If i use the raid utility from the motherboard it doesn't appear during disk detection, so i disabled it. I've rebooted and launch installer from the DVD and it displays correctly 4 HD. I've configured them, installed the OS and installed GRUB in MBR (grub install /dev/sda /dev/sdb /dev/sdc /dev/sdd). But when i reboot it asks me to switch for a correct system disk.
I've look into BIOS configuration. If i make a raid array using the bios utility, i can choose any array in boot device priority, but if there is no array defined, i can't select anythig (but the DVD drive).

Short story: Correct driver for 10.1 for the raid on the Intel S3000AH board?
Long story: This system crashed due (I think) to a bad memory module, had been running fine for 2 years, had been an upgrade from Suse9. The hardware is fixed but I get "GRUB" repeating on the screen when booting and that is all. I can't seem to find opensuse drivers for 10.1 (that is what I believe is on the system, I believe the data is still intact and don't want to compromise it if possible) It will not load the 10.1 drivers from the intel site, presumably (?) because they are for SLES, not opensuse. I can boot from a 9.3 CD with the drivers from the intel site, and can see the original partitions.

I shall start off by saying that I have just jumped from Windows 7 to Ubuntu and am not regretting the decision one bit. I am however stuck with a problem. I have spent a few hours google'ing this and have read some interesting articles (probably way beyond what the problem actually is) but still don't think I have found the answer.I have installed:
Distributor ID: Ubuntu
Description: Ubuntu lucid (development branch)
Release: 10.04
Codename: lucid
I am running the install on an old Dell 8400. My PC has an Intel RAID Controller built into the MB. I have 1 HDD (without RAID) (which is houses my OS install) and then I have 2 1TB drives (These are just NTFS formatted drives with binary files on them nothing more.) in a RAID 1 (Mirroring) Array. The Intel RAID Controller on Boot recognizes the Array as it always has (irrespective of which OS is installed) however, unlike Windows 7 (where I was able to install the Intel RAID controller driver) .Does anyone know of a resolution (which doesn't involve formatting and / or use of some other software RAID solution) - to get this working which my searches have not taken me too?

While building my new server I grinded ta hold shortly after inserting the FDR10 DVD.
Hardware:
Chenbro es34069
Albatron KI690-AM2
AMD Athlon X2 64 4850E
IDE 2.5" HD (master)
IDE Slimline DVD (slave)
4x SATA II swap (still empty)
It stops at the message "net: Registered protocol family 2" but in one of my desperate attempts I changed almost every setting in my BIOS (updated to 1.07) and all of a sudden it passed on. Stupid enough I figured it would be a small effort to find the setting and figure out the problem, so I changed them one at a time after loading the defaults....

I have been thinking about upgrading my RAID setup from a pair of Intel X25s running the software based RAID included with ubuntu to four Intel X25s running off a PCIe based controller. The controller is an HP P400 which I know works great on ubuntu (I have other machines running it with SAS drives). My desktop has an Intel S5000XVNSATAR mainboard and I have an open PCIe v1.0 8x (physical) slot that is wired 4x. The controller is 8x and will fit fine. How much of a performance hit do you think I will see running this 8x controller in the slot wired 4x with four Intel x25s in a RAID 10? Will I have enough bandwidth with the 4x for those SSD's?

I want to build a 6xSATA RAID 5 system with on of the disks as spare disk. I think this give me a chance of 2 of 6 disks failing without losing data. I am right? Hardware: Intel ICH10R First I will creat a 3xSATA RAID 5, after I will add the spare disk and after that I will add the others disks. This is what I think I should do.
[code].....
EDIT:I'm thinking in put LVM with the RAID 5. What are the advantages and disadvantages of it (LVM over RAID 5). It is safe? My MB (Asus P5Q) have Chipset Intel P45 ICH10R. What kind of RAID have it? Hardware RAID, fake RAID, BIOS RAID, software RAID? This are the specs of storage

I have a dell inspiron 530 desktop with core 2 quad and 4GB memory, running 32bit vista and 64 bit fedora 10. I searched on the web with "can I install 8GB memory on dell inspiron 530", and got couple of articles that says I only needed a bios upgrade.I downloaded bios version 1.0.18 from dell and run that in Windows to replace bios 1.0.12.After it said upgrade successful and asked me whether I wanted to reboot to have the new bios taking effect, and I said yes. And it shutdown the computer, and never came up Now, when power up, I see nothing, not even the "F2 to setup, F12 to boot menu" message, much less the grub selection. Is there a way to revive the computer?

I have a Dell Vostro with sda and sdb (the latter was installed by myself). I installed FC14 x86 64 onto sdb with /boot being on /dev/sdb8
I did not want to install grub onto /dev/sda as this is a shared machine. I thought that I would be able to use the BIOS's 'select boot device' to select the sdb disk and boot off that and get into FC that way.
fdisk verifies that /dev/sdb8 is marked as bootable and grub (via find /grub/stage1) confirms that it is installed on hd1,7 (ie /dev/sdb8)
However, no matter which hd is choosen as the boot device, Windows is always booted - I change the boot order to use: DVD, sdb, sda but it still boots Windows. It seems like the BIOS only wants to boot sda no matter what.

Server has DQ35JO board, 8GB memory, multiple SATA hard drives. It was happily running Fedora 10, and Fedora 9 before that. I downloaded and burned the F11 DVD, booted it, did an install which is:
-- delete the LVMs
-- create a 200 MB /boot on ext3, the rest of /dev/sda on ext3 as /
-- reformat the swap partition on /dev/sdb1
-- leave the other file systems alone (they are all ext3)
I chose no optional packages and let it install. It finished normally and got to the "click to reboot" screen. Now, my server is completely bricked. When I power it up I get a blank screen with a blinking cursor. I cannot even get to the BIOS, or boot my Fedora DVD, much less boot the boot drive.

I'm trying to install Debian Lenny on my new Dell XPS 8100 Desktop with 2 x 1To SATA HD. (No Windows or any other OS install is present on the system) The Bios allows me to change the SATA mode to either "ATA" or "RAID"
- When SATA mode is set to RAID, the installation goes without issues, but when it comes to load into the system, I've got that Stage 1.5 Grub Loading... Error 2 problem. I assume this is due to the Bios "RAID" configuration. I then switched the SATA mode to "ATA" in the Bios and now I can see the menu that allows me to boot my debian install but that part actually fails too saying "ALERT /dev/sda1 does not exist"
- When SATA mode was set to ATA, I tried to re-install the system but this time my drive was not recognized by the installer: "No common CD ROM drive"

I've tried to install Fedora 11, both 32 and 64 on my main machine.It could not install as it stops on the first install window. I've already filed a bug but really haven't seen any feed back yet.The bug has something to do with Anaconda and the Raid array but I really can't tell.
I have an Intel Board (see signature). I am running intel raid software under W7 currently.It works fine. But, I'm wondering, when I attempt to install F!!, is my current raid set-up causing problems? Do I need to get rid of the intel raid software and use a Fedor/Linux raid program to manage the raid array??
