Ubuntu Installation :: Rebuild Status Raid 1 Intel Isw Fakeraid Intel?
Oct 1, 2010
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

Gparted does not recognize my intel ICH7 fake raid 0 partitions rendering it useless. Am I missing a package that will add this? I know the live disk can do this. Is it something to do with dmraid? using 10.04 64 bit ubuntu

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?

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.

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.

Are Intel wireless cards compatible with non-intel-based laptops? In my case I wish to upgrade the current Atheros-based mini pci express wifi card with the Intel 4965agn. It is an Asus 4520 with an AMD Athlon X2 processor and nvidia nForce chipset.

! I'm thinking of buying a corei5-660 on a motherboard with an Intel H55 Express Chipset. Does anyone know if it's fully compatible with OpenSUSE 11.3? I mean video (that comes from the processor, not an off-board PCI), audio (HD Audio), networking (Intel� 82578DC Gigabit), SATA Controller, USB, etc. I've tried to google but didn't find much info so I wonder if anyone is using or knows where I can find more info about it...
I have found this thread on the forums about the H55 chipset: Core i3 Intel Clarkdale graphic controller problem But the problems were facing on 11.2, I don't know about 11.3...

I've installed Suse linux 11.3 (kernel 2.6.34.7-0.5) on my brand new computer HP all in one 5130. Everything worked incredibly well : Wifi, wireless keyboard and mouse, sound, webcam.. There is only one remaining issue : I get a very poor resolution (1280x1024) instead of the 1920x1080 allowed by the screen. The graphic card is an intel chipset (HD graphics) integrated to an intel core i3 CPU. Here is (part of) the X11.org log :

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).

About a year ago I bought a new compy and decided to get on-motherboard RAID, and by golly I was gonna use it, even if it wasn't worth it.
Well, after one year, two upgrades, a lot of random problems dealing with RAID support, and a lot of articles read, I have come to my senses.
The problem: I have a fakeraid using dmraid, RAID 1, two SATA harddrives. They are mirrors of eachother, including separate home and root partitions. I actually found the method I think I had used here: [URL]
The ideal solution: No need to reinstall, no need of another drive, no need to format.
My last resort: Buy a drive, copy my home directory, start from scratch, copy my stuff over.
PS: if it matters, I'm on 64 bit 10.04 LTS

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?

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?

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 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.

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

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":

and the partition in it was not available as device special file in /dev:

The situation: computer based on Asus P6T motherboard. Two RAIDS:
- 'boot', on motherboard built-in RAID controller (CentOS 5.5 installed on this RAID)
- 'data' on 3dware RAID card
At one moment a CPU fan fails and the system halts. After the fan is replaced, BIOS informs it's reset and all the inner controller data are forgotten. After I switch it to 'RAID' mode, it remembers it was a mirror raid (RAID 1) installed, but the file system on it is completely trashed.
The 'data' RAID run by external controller isn't affected by the system failure. Three questions:
- is it worth trying to install OS on the rebuilt 'boot' RAID once again? Looks like if BIOS settings are lost for some reason, there's chance of completely losing RAID data
- has someone encountered similar problem with built-in RAID nd was it possible to recover data?
- will the software RAID be worth creating instead of using hardware RAID to replace the 'boot' drive?

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 cannot install 11.3 on a machine with an intel raid controller I have tried with raid 1 using the card and then setting the disks to individual raid 0 and letting suse raid them. With the card doing it the machines crashes as soon as it tries to boot the first time, with suse doing the raid I just get 'GRUB' on the screen It seems a lot of people are having similar problems, does any one have any pointers. 11.2 installs fine. I would try and do a bug report but every time I go to the page it's in Czech

I've a Centos 5.1 server on S5000vsa Intel board with 6 bay HD in raid 1 mode (2 HD), and working fine until I've decide to make a yum update. Today the Centos is 5.4 but seems necesssary to upgrade the megasr driver for the raid function (i.e. , is not possible to contact the raid firmware trought Web Console 2). I've download the last megasr driver from Intel and I follow the instruction to upgrade the driver with s.o. installed, but when I start the server and choose via grub the new img boot file, the display show :
megasr.ko invalid module format -1 and stop. The linux version is the same in the machine (uname -a) and from the driver (2.6.18-164.9.1.el5). Another question : in Intel instruction spoken about megasr.o , but on img file I found a megasr.ko . I think instructions referre to old linux 2.4

I had Ubuntu 8.04 installed on server#1 and moved it to server#2. Everything works fine, including the changing of eth2/3 back to eth0/1. I was wondering if it's possible to use the nvidia onboard raid and make a raid 1 with this OS not getting wiped out. It's a bios level cheesy raid and it warns that it's erasing the data (which is didn't erase), but wont boot anyway. I'm assuming it's probably best to just create a software raid in the working OS with a fresh 2nd drive.

I'm trying to figure out how to install Ubuntu on top of Windows 7 on my intel X-25 M G2 SSD. I bought the SSD a while ago and installed Win 7 without partitioning it. Soon, I got sick of worrying about the wear and tear, and chucked it into my drawer. Instead, I installed Ubuntu on my HDD, and forgot about the SSD. Now that I need to dual-boot because of some obscure VM-bashing ActiveX plugins,
I need to install Ubuntu on my SSD. However, I'm overwhelmed and confused. I just have no idea how to do just that. What steps should I take to install Ubuntu without messing up Win 7 on my SSD? I need general pointers like align your drive, manually partition for ubuntu, and the like. I think I can plough thorough howtos and find out necessary details. I've been searching, but my effort was fruitless mainly because I didn't know what was involved.

Since Karmic has come out, this chipset crashes Ubuntu and, months later, this has not been fixed. (See bug #456902). So I had to re-install Ubuntu 9.04. Thinking this was a Ubuntu problem, I went out and bought a Linux magazine with a Fedora 12 inside. This was after I had downloaded the same distro but couldn't get the install going because of the proverbial chipset. After re-installing 9.04, after I installed Fedora 12 twice, I am now back to a crappier display then the one I had when I decided to "upgrade" to Ubuntu Karmic in November.I cannot afford a new computer nor Windows 7.
