Fedora Hardware :: RAID - Intel Matrix Storage Manager
Mar 28, 2010
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.

Ubuntu 2.6.31 - 14 generic
Problem began with RAID0 failure using 2 WD FALS1001 HDDs. I was unable to boot so I replaced the drives with 2 new FALS1001. Installed Win7 64 Ult, installed/updated all drivers/OS and had the same problem with one of the RAID drives again. Usually blue screens with Kernel_stack_inpage_error. I have Intel Matrix Storage version 8.5.0.1030 and can usually boot back into windows even when one disk out of the array shows unknown error (0) and reset the disk to normal. Now it seems to be progressing worse and hit or miss, I can get Windows to load 1 time out of 20 posts.
Sometimes the array shows normal, sometimes failed, sometimes unknown error (0) and other times, everything shows normal and healthy and attempts to boot windows but has read errors or unable to find OS errors. I simply want to access my data via Ubuntu so I can back it up and wipe the drives for re-installation. I see that Intel shows support for Linux but I'm lost as to what I need to do next. Intel link: [URL]. I currently see one of my drives listed in Ubuntu as a RAID component and the other is listed as a hard drive with unknown information. I have loaded mdadm but I'm unfamiliar with how to use it.

I've been using Slackware 13.0 32-bit because of a problem supporting RAID 0 metadata for Intel Matrix Storage Manager. I would like to move to 64-bit with Slackware 13.1 but I can't see any way to use a 64-bit kernel with my RAID setup. Because the "mdadm" in Slackware does not support the "-e imsm" option to read Intel Matrix Storage Manager Metadata I have been using "dmraid". Unfortunately I'm having trouble finding a way to make "dmraid" (a 32-bit application) work on 64-bit Linux. It appears that "dmraid" may be unsupported now, and I can't find a good place to get current source to compile on a 64-bit system. Essentially "dmraid" is only a program to interpret metadata and then configure the standard Linux device mapper to set up the required mirror or stripe mapping. So, it actually does not have to interact directly with the kernel.
I believe it only issues I/O requests to read disks and configure "dm" devices. So far I have not had to rebuild "dmriad" since Slackware 10. I don't know if 32-bit libraries are an option, or if those can be added to an initrd image (required to use dmraid before booting). People claim that "mdadm" will work with Intel Matrix Storage RAID 0 but I have never found any detailed information about how to do that. When I've tried the few examples I've run across on Slackware I just get an error that the "imsm" metadata format is not supported. I have not been able to locate a site to browse Slackware packages. I was hoping to find "dmraid" in the 64-bit packages. I think "dmraid" was at one time in Slackware but perhaps not any longer.

There is not showing any size or anything. I have set two raid arrays: main and storage, both with 4-hard-driver (raid10). Storage array is partitioned to 1TB and 400GB partitions, 400GB partition is where i want to install ubuntu. Main array has windows already. Where to go next?

I got opensuse 11 running on a dedicated HDD and got another 4 HDDs created as RAID 10 via the Intel Matrix RAID Controller of the ICH10 southbridge. I simulated a device failure and disconnected one of the drives and during POST the controller simply says that I need to rebuilt the array from the OS. So how am I supposed to do that since there were no usable raid utitlities for openSuSe delivered out of the box.

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

It's been a real battle, but I am getting close.I won't go into all the details of the fight that I have had, but I've almost made it to the finish line. Here is the set up. ASUS Z8PE-D18 mother board 2 CPU, 8 Gig Ram. I recently added an OCZ Agility SSD, defined a raid 1 virtual disk on the 1 terabyte WD HDD drives, which will holds all of my user data, the SSD is for executables.The bios is set to AHCI. Windows 7 installed fine, recognizes the raid VD just fine.
I installed Ubuntu 10.04 by first booting into try and mode, then opening a terminal and issuing a "sudo dmraid -ay" command. Then performing the install. I told it to install the raid components, and told it to let me specify the partitions manually. When setting up the partitions, I told it to use the free space I set aside on the SSD from the Windows 7 install as ext4 and to mount root there. Ubuntu installed just fine, grub2 comes up just fine, and Windows 7 boots with out a hitch, recognizing the mirrored partition as I indicated previously. When I tell grub to boot linux however, it pauses and I get the "no block devices found" message. It will then boot, but it does not recognize the raid array. After Ubuntu starts up I can run "dmraid -ay" and it recognizes the raid array, but shows the two component disks of the raid array as well. It will not allow the component disks to be mounted, but they show up which is annoying. (I can live with that if I have to)
I have fixed a similar problem before by setting up a dmraid script in /etc/initramfs-tools/scripts/local-top ... following the instructions found at the bottom of this blog:[URL].. To recap: My problem is that after grub2 fires up Ubuntu 10.04.1 LTS (Lucid Lynx), it pauses, and I get "no block devices found" It then boots but does not recognize the raid array untill I manually run "dmraid -ay". I've hunted around for what to do but I have not found anything. It may be some timing issue or something, but I am so tired of beating my head against this wall.

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.

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:

I have the latest ubuntu V10 and trying to set up a raid 5 to use as storage. I have 3 1 TB drives along with the 160 GB OS drive. Is what I want to do possible and is there a gui interface to perform this or clear instructions on how to accomplish this? I am a novice when it comes to Linux but trying to ween myself off of Microsoft.

I am in a situation where I am stuck with a LVM cleanup process. Although I know a lot about AIX LVM , but this is first time I am working with Linux LVM2. Problem is that I created two RAID arrays on storage, which appeared as mpath0 & mpath1 devices (multipath) on RHEL. I created logical volumes and volume groups and every thing was fine till I decided to clean the storage arrays and ran following script:
#!/bin/sh
cat /scripts/numbers | while read numbers
do
lvremove -f /dev/vg$numbers/lv_vg$numbers
vgremove -f vg$numbers
pvremove -f /dev/mapper/mpath$numbersp1
done
Please note that numbers was a file in same directory, having numbers 1 and 2 in separate line. Scripts worked well and i was able to delete definitions properly (however I now think I missed one parted command to remove the partition definition from mpath device. When I created three new arrays, I got devices from mpath2 to mpath5 on linux and then I created vg0 to vg2. By mistake, I ran above script again for cleanup purpose and now I got following error message
Cant remove physical volume /dev/mapper/mpath2p1 of volume group vg0 without ff[/B]
Now after doing mind search, I now realize that I have messed up (particularly because mpath devices did not map in sequence to vg devices and mapping was like mpath2 --- to ---- vg0 and onwards). Now how I can cleanup the lvm definitions? should i go for pvremove -ff flag or investigate further? I am not concerned about data, I just want to cleanup these pv/vg/lv/mpath definations so that lvm can be cleaned up properly and I can start over with new raid arrays from storage?

I am interested in turning my home server into something that I can store backups on. I do photography and therefore have a lot of photos. I use Mac OS X for my photo editing, so it must be accessible from my Macbook. I am new when it comes network storage servers, so what would be the best solution for me to be able to backup my photos seamlessly? I would like it easy enough so others can backup files without any terminal commands and such. What would you suggest? CIFS? RAID? iSCSI?

So my aim is to install openSUSEx64 11.3 onto my Macbook; but for whatever reason, upon boot-up, the system won't recognize the USB thumb drive with the expanded image of openSUSE on it. I followed steps in Terminal to expand the image onto the said USB stick and know it worked properly because Terminal said "Process Completed." Do I need a special type of USB thumb drive or am I missing something? I am using a late-2009 Macbook. By the way, these were the steps used to prep the USB thumb stick:
1. Open a Terminal (under Utilities)
2. Run diskutil list to get the current list of devices
3. Insert your flash media
4. Run diskutil list again and determine the device node assigned to your flash media (e.g. /dev/disk2)
5. Run diskutil unmountDisk /dev/diskN
6. Execute sudo dd if=/path/to/downloaded.img of=/dev/diskN bs=1m
7. Run diskutil eject /dev/diskN and remove your flash media when the command completes

The intention is to have this system dual-boot. When i first put it together, i decided to setup a raid5 array spanning 3 sata drives. I installed Windows 7 first, decided i'd get to Linux later. I left 150mb or so at the beginning of the array for /boot, and about 200gb at the end for my linux install. i'm getting to the linux install. My distro of choice is Fedora 12. I start the setup, and at the point where it's time to partition, the installer tells me that its unable to find any suitable storage devices.
I Crtl-Alt-F2 to a console, and fdisk -l. Fdisk reports three individual drives which all have partitions already. All have free space. None make sense. So i turned to google, and found some threads which explain that this chip doesn't run a true raid, rather its what's been referred to as fake raid. Which is that it depends on the windows driver in order to actually present the array to the OS, and that the best way to get by that on linux, is to break the array, and use LVM instead.
That's all well and good, but i lose two things in doing that. First i lose the resiliency of raid 5, and second, well, what does that do to my windows install? I've considered moving all of my data from windows to other machines, and then just starting from scratch, but i'd really much prefer a method of using the chips fake raid in linux. Is there a driver, or module which i can install to make this happen?

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 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?

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
