Ubuntu :: Installing In A Intel S875WP1-E With Raid?
Oct 29, 2010
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).
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
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 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:
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?
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.
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
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":
[Code]...
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?
Could any RAID gurus kindly assist me on the following RAID-5 issue?I have an mdadm-created RAID5 array consisting of 4 discs. One of the discs was dropping out, so I decided to replace it. Somehow, this went terribly wrong and I succeeded in marking two of the drives as faulty, and the re-adding them as spare.
Now the array is (logically) no longer able to start:
mdadm: Not enough devices to start the array.Degraded and can't create RAID ,auto stop RAID [md1]
Code: mdadm --create --assume-clean --level=5 --raid-devices=4 /dev/sda2 /dev/sdb2 /dev/sdc2 /dev/sdd2 As I don't want to ruin the maybe small chance I have left to rescue my data, I would like to hear the input of this wise community.
I'm trying to install 11.04 and setup software raid on two hdd's in the process for the home partition. Even in the manual setup I don't really see any option to do this.
I am attempting to run Ubuntu 10.04 Server on RAID 1 and am consistently hitting the same issue when trying to boot the system for the first time (after what seems to be a successful install of the OS). I am creating the RAID 1 using the directions found in the Ubuntu Server Guide. The error I receive when trying to boot the system for the first time is...
Code:
mount: mounting /dev/disk/by-uuid/f35415ee-4c14-4eb1-995f-f19fbcd760c7 on /root failed: Invalid argument mount: mounting /dev on /root/dev failed: No such file or directory mount: mounting /sys on /root/sys failed: No such file or directory
I've just installed ubuntu 10.04 via wubi through windows 7. Installation seems to have worked fine but i'm having trouble establishing a network connection. The network card is an Intel (R) Pro 100 /ve. It seems that the card has tried to establish a connection via IPv6, when I believe it should be connecting via IPv4.
I am totally new to Ubuntu but have been tinkering for a week now. Can't say I have figured a thing out, thank God for Google, Linux is just not for the novice user. I guess thats where Windows comes in but I really like the stability of Linux and the fact it is Open Source and free. Wish I was a cool programmer or someone who has worked with the OS for a while, that would make things a lot easier. Where can I study up and get a little more educated about what I am doing? Anyway hopefully someone can answer the driver question. Lastly is there anyway to get Hardware Acceleration if using an Intel i5 system?
I just got a new desktop PC with Intel i5 650 Dual Core 3.2GHz 4M Turbo. I would load up the installation cd, once I selected to install the screen would go blank and nothing happens. Centos 5.4 work, but I just want Fedora 12 installed.
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 was recently given two hard drives that were used as a raid (maybe fakeraid) pair in a windows XP system. My plan was to split them up and install one as a second HD in my desktop, and load 9.10 x64 on it, and use the other for mythbuntu 9.10. As has been noted elsewhere, the drives aren't recognized by the 9.10 installer, but removing dmraid gets around this, and installation of both ubuntu and mythbuntu went fine. On both systems after installation however, the systems broke during update, giving an "read-only file system" error and no longer booting.
Running fsck from the live cd gives the error: fsck: fsck.isw_raid_member: not found fsck: Error 2 while executing fsck.isw_raid_member for /dev/sdb and running fsck from 9.04 installed on the other hard drive gives an error like:
The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device>
In both cases I setup the drives with the ext4 filesystem. There's probably more that I'm forgetting... it seems likely to me that this problem is due to some lingering issue with the RAID setup they were in. I doubt its a hardware issue since I get the same problem with the different drives in different boxes.
I am having trouble installing Ubuntu 10.04 on a HP Z600 with a two disc raid system. Is there a way to solve this without using the alternate cd (where the data files seem to be corrupted). The regular 10.04 cant find any drives on which to install, the 10.04 alternate cd�s all have corrupted files. I have tried downloading the .iso from two mirrors as well as from .torrent, all have data problems. The HASH checksums are fine, only the data on the burned discs are wrong. I have also tried using a USB install, but there are problems there aswell. At the moment I have win 7 on the disc as on the other partition, and have been using Ubuntu 10.10 (that is now an unbootable broken system), but have to downgrade to 10.04 becasue of software requirements.
The RAID seems to be an INTEL Raid . From HP homepage: Integrated 6 channel SATA 3 Gb/s controller with RAID (0, 1, 5 or 10) capability, optional SAS controller, LSI 3041E 4-port SAS/SATA, with RAID (0, 1 or 10) capability
I tried install Centos 5.2 (i386) on Dell PowerEge 2950 server with SAS RAID disk (RAID 5 on PERC 6/i created from six HDD, 1 TB each). I never installed Centos on a disk over 2 TB. I find out that i need use gpt instead mbr. I tried use rescue mode + parted but after rebooting I got message "Can't boot from from GPT partition" whet tried install. But when the space is partitioned by installer, I can't boot up.I got msg PBR not found. My ask is: "Can I boot directly from GPT partition? If yes how do it?" Or even better "How to install centos 5.2 on disk bigger than 2 TB?"
What are the things that i need to do to be able to install CentOS 5.3 on RAID 1 drive.I have tried to install other OS like Ubuntu 9.10 and lower and they all work fine.Problem is that, during the initial installation, it could not find any drive therefore i could not proceed with the installation.
i was going to do this project of installing Debian on a NAS Intel SS4000e . The part i got stuck is that i cannot stop the Redboot from booting up. i.e using CTRL+C. The NAS uses the latest firmware from Intel Ver1.4 . The serial cable is tested and i used the following pin out [URL]... nsoleCable and the comport settings are as follows
I am looking for a assembler, in my college there is a ia32build assembler. I have tried searching it in Google, but I can't find it. I have x86 processor and I want to install it in Ubuntu 10.4.
Edit 1 : I am not sure about the assembler name but we assemble it by ia32build command.
Edit 2 : The syntax is quite different from nasm. Here's my sample code.

I'm trying to install GRUB2 on root partition under RAID 5. I tried using the alternate CD, but installation failed. Now I'm trying under the live CD and grub-install ... but I'm being told it can't find the device even though /dev/sda2 (root partition) and /dev/sda are mounted.I have 4 discs, each with a swap partition (/dev/sdX1) and a root partition (/dev/sdX2).
I have a raid 0 setup with 2 x 1TB drives. I have an ASUS P8P67 LE motherboard and am using Interl RST for the Raid setup. I'm utterly ignorant of raid and therefore forgive any mistakes... I already had windows 7 installed and was attempting to dual boot ubuntu.
I installed Ubuntu from CD. The raid was picked up properly as only one drive by ubuntu. So it picked up the windows MBR and the main windows partition. I resized the main partition and used the "install ubuntu and windows 7 side by side" option. Installation went fine but once I restarted the PC I was welcomed by a grub rescue screen with the message: "error: no such device e196.....". Edit: I used the Windows 7 disc to repair the windows bootloader so I can now boot into Windows 7.
Before doing so I used gparted on the live cd to check the partitions on the drives. The only ones present were the MBR and windows one. So ubuntu seemingly didn't install... Although GRUB did... I was advised by someone on the ubuntu IRC chat to avoid trying to reinstall ubuntu at that point just in case there was an error in the partitioning process. I've since checked the state of the partitions from within windows and there's the MBR partiton, the windows partiton AND the partition that I created for ubuntu... 965MB of the partition that I created is listed as used space as well...
