Ubuntu Installation :: Boot Disk Image For Install On AMD RAID PC?
Sep 3, 2010
I tried installing Ubuntu 10.04 WS on my PC but it did not see any disks to install on. I believe this is because my drives are all configured as RAID. My mobo is an Asus M3A78-EMH HDMI AM2+ socket with an Athlon 2X 5000+ CPU. The chipset is AMD 780G. I have the BIOS configured for RAID drives and I already run Win XP x32 and Win 7 x64 on it. My boot drive is configured as 'RAID READY' and I have 2 RAID 1 disks consisting of pairs of SATA drives.
From what I have researched it seems that with some tuning it should be possible to install Ubuntu 10.04 but I have little Linux experience and don't want to mess up my existing drives. I have installed Linux before a few times and run it but never with RAID. Is anyone aware of an existing disk image that I will be able to install from on my system or would it be possible for someone to create one for me to use?

I was running Ubuntu 9.04 Desktop on a headless Pentium 4 machine which is our file, mail, web & fax server. The two x 250GB SATA hard disks were in a RAID 1 array with full disk encryption. Ran the 9.10 upgrade via WEBMIN and it failed. I should have known then to copy over everything to a backup disk, but instead I rebooted.
On restart the machine accepted my encryption passphrase but promptly hung with a mountall symbol lookup error - code 127. So I can't start the machine to get at the disks, and using a Live CD is useless as it has no way to open the RAID array to get at the encrypted partitions. Although we have data backed up (as at last night) I'd hoped not to have to rebuild the entire server from scratch. But its looking bad.I have taken one drive out and plugged it into another machine (Hercules), and the partitions show up as /dev/sdb1 /dev/sdb2 /dev/sdb3.
If it weren't for RAID, I could open /dev/sdb2 the main partition) in Disk Utility and enter my encryption passphrase to get access. But RAID adds a layer of obstruction that I have not yet overcome. I used mdadm to scan the above partitions and created the /etc/mdadm.conf file, which I edited to show the 2nd drive as missing (rather than risk corrupting both drives). I activated the RAID array with mdadm, and cat shows:
Code:
root@HERCULES# cat /proc/mdstat
Personalities : [raid1]
md1 : active raid1 sdb3[0]
1815232 blocks [2/1] [U_]
[Code]...
I've been searching the web for hours but have yet to find someone with a solution to this situation. If anyone has a thought on how to access this disk I'd be pleased to hear from you. In the meantime I will start building a new (9.10) machine from scratch, without RAID, 'cos that's probably going to be necessary.

How can i get a RAID virtual image disk?
What i need is to mount several directories from any other partiton (or file system) as a new merge file system that can grow or decrease depending on the free space. As if it was a dinamic RAID,so i can work with huge files distributed over the partitions mounted.
Ejemp: /mnt/sda1/dir_raid1 + /home/dir_raid2 + /mnt/sda3/dir_raid3 ---> /mnt/RAID/
mhddfs and unionfs <---- are not the solution im searching (cant use huge files)

I am running a 14 disk RAID 6 on mdadm behind 2 LSI SAS2008's in JBOD mode (no HW raid) on Debian 7 in BIOS legacy mode.
Grub2 is dropping to a rescue shell complaining that "no such device" exists for "mduuid/b1c40379914e5d18dddb893b4dc5a28f".
Output from mdadm:
Code: Select all # mdadm -D /dev/md0
/dev/md0:
Version : 1.2
Creation Time : Wed Nov 7 17:06:02 2012
Raid Level : raid6
Array Size : 35160446976 (33531.62 GiB 36004.30 GB)
Used Dev Size : 2930037248 (2794.30 GiB 3000.36 GB)
Raid Devices : 14
[Code] ....
Output from blkid:
Code: Select all # blkid
/dev/md0: UUID="2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb" TYPE="xfs"
/dev/md/0: UUID="2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb" TYPE="xfs"
/dev/sdd2: UUID="b1c40379-914e-5d18-dddb-893b4dc5a28f" UUID_SUB="09a00673-c9c1-dc15-b792-f0226016a8a6" LABEL="media:0" TYPE="linux_raid_member"
[Code] ....
The UUID for md0 is `2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb` so I do not understand why grub insists on looking for `b1c40379914e5d18dddb893b4dc5a28f`.
**Here is the output from `bootinfoscript` 0.61. This contains alot of detailed information, and I couldn't find anything wrong with any of it: [URL] .....
During the grub rescue an `ls` shows the member disks and also shows `(md/0)` but if I try an `ls (md/0)` I get an unknown disk error. Trying an `ls` on any member device results in unknown filesystem. The filesystem on the md0 is XFS, and I assume the unknown filesystem is normal if its trying to read an individual disk instead of md0.
I have come close to losing my mind over this, I've tried uninstalling and reinstalling grub numerous times, `update-initramfs -u -k all` numerous times, `update-grub` numerous times, `grub-install` numerous times to all member disks without error, etc.
I even tried manually editing `grub.cfg` to replace all instances of `mduuid/b1c40379914e5d18dddb893b4dc5a28f` with `(md/0)` and then re-install grub, but the exact same error of no such device mduuid/b1c40379914e5d18dddb893b4dc5a28f still happened.
[URL] ....
One thing I noticed is it is only showing half the disks. I am not sure if this matters or is important or not, but one theory would be because there are two LSI cards physically in the machine.
This last screenshot was shown after I specifically altered grub.cfg to replace all instances of `mduuid/b1c40379914e5d18dddb893b4dc5a28f` with `mduuid/2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb` and then re-ran grub-install on all member drives. Where it is getting this old b1c* address I have no clue.
I even tried installing a SATA drive on /dev/sda, outside of the array, and installing grub on it and booting from it. Still, same identical error.

We have some servers that run in very harsh environments (research vessel) that need to have high-availability.We have software RAID 1 for some measure of resiliency, along with proper data backups (tapes etc), however we would like to be able to break out a new server and re-image it (including RAID setup) from a known good copy if the hardware completely fails on the production box. Simplicity of the process is a big plus.I am interested in any advice on the best way to approach this. My current approach (relatively new to Linux administration, totally new to MDADM) is to use DD to take a complete gzipped copy of one of the RAID'ed devices (from a live CD): ode:
dd if=/dev/sda bs=4096 | gzip -c > /mnt/external/image/test.img then reverse the process on the new PC, finally using Code:mdadm --assemble to re-create and re-build the array.

my Fedora 11 system is not starting anylonger. It stops with the message:
Code:
VFS: Can't find ext4 filesystem on dev dm-0
The system told me since a while, that a lot of the sectors of one disk of the (software) RAID compound are failed already. So tried to disconnect each of the disks and start them separately. Unfortunaltly this is not working (for one its is not working at all, the other wents the same far as with both), when I tried to recover the system with the Fedora DVD, it said no distribution found. I am quite new and do not know so much about linux system, so i do not know what further information you could need. Maybe it can be important, that both disks are encryped (the system wents so far, that I can type in the password).

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'm a Linux newbie and are trying to install F13 from bootable USB onto the HD of a DELL mini netbook. I've followed the install wizard's defaults including the "Use All Space option." The install errors out at about 20% of progress during the "Copying live image to hard drive" process. The error dialog is as followed:"There was an error installing the live image to your hard drive. This could be due to bad media. Please verify your installation media..." and it comes with options to Exit installer or Retry. I have since retried and restarted several times and still came to the same error. FYI, I've initially attempted to install F13 to the HD over an existing Windows XP.

I had done a new lucid install to a 1 TB RAID 1 array using the alternate CD a few weeks back. I messed up that system trying to some hardware working that lucid doesn't have drivers for yet, so I gave up on it and reinstalled to a single 80 GB disk that I now want to move over to the RAID array.
I moved all of the existing files on the array to a single folder, then copied all of the folders from the 80 GB disk over to the array with permissions and symlinks (minus the contents of /proc and /sys, which I created empty).
These are the commands I used:
Quote:
p -a -d -R -v -t /media/raid_array /b*
cp -a -d -R -v -t /media/raid_array /d*
cp -a -d -R -v -t /media/raid_array /e*
cp -a -d -R -v -t /media/raid_array /h*
[Code]....
I tried to change fstab to use the 689a... for root, but when I try to boot, it's still trying to open /dev/disk/by-uuid/412d...
So then I booted from the single disk again and chrooted into the array, then ran update-initramfs -u. I got 3 "grep: /proc/modules: No such file or directory" errors, and "cat: /proc/cmdline: No such file or directory"- so I created directory /proc/modules, created an empty file /proc/cmdline, and ran the initramfs update again. Then I tried to shut down, which hung (probably because I was doing all of this from a terminal window in Gnome), so I killed the power after a couple of minutes.
It's still trying to use /dev/disk/by-uuid/412d... to boot.
What am I missing? I assume I just have to change the UUID to mount as root, but I don't know how.

I am currently with Wubi 10.04 under Vista and my Dell XPS 630i has a 1 TB Nvidia RAID controller.First image (Option A) suggests /dev/sda as device for boot loader installation, while second image (Option B) suggests /dev/mapper/nvidia_bcidhdja.I think that the way of keeping the RAID would be using Option B as the device for boot loader installation. Would Option A break the RAID instead?

I'm having serious troubles to install ubuntu-10.04.1. My raid is an hardware raid with intel chipset. Note that win7 is already installed and working with my raid. I made some space from windows, to install Ubuntu (40gb). First, I run the installer, everything seems to be fine. I choose to install Ubuntu were there is the most space free (sorry, I'm not sure about the real terms used there).
Then my partition with the vista loader appears. So the installer can see my raid, and should work fine (everything is detected correctly). But once I'm in the end of the installation (around 95%), a pop-up appears, and tells me that Grub can't install in /dev/sda and it's a fatal error. I can choose an another destination, but it doesn't seems to work.

I have installed Ubuntu on my m1530 since 8.04 and currently dual boot Win7 and 10.10. I would like to dual boot on my PC, but I have run into a problem. I am not a pro at Ubuntu, but this problem I can not solve by reading forums like I have in the past.
I realize this is a common problem, but I have noticed people having success.
I have a M4A87TD EVO MB with two Seagate drives in Raid 0. (The raid controller is a SB850 on that MB) I use the raid utility to create the raid drive that Windows7x64 uses. I have 2 partitions and 1 unused space. Partition 1 is Windows, partition 2 is for media, and the remaining unused space is for Ubuntu.
I am running ubuntu-10.10-desktop-amd64 off a Cruzer 16GB flash drive that was installed via Universal-USB-Installer-1.8.1.4.
My problem like so many others is that when I load into Ubuntu, gparted detects two separate hard drives instead of the raid. I read that this is because kpartx is not installed on 10.10. I then went in LiveCD mode and downloaded kpartx from Synaptic Manager. Gparted still reported two drives. I opened terminal and run a few commands with kpartx. I received an error. (Forgive me I didn't write it down, but I believe it said something about a communication error. I will try again later and see.)
Currently I am reflashing the Cruzer with a persistence of 4GB. I am not familiar with this process, but I understand that my LiveCD boot will save information I download to it. I decided to try this method because I was going to install kpartx and reboot to see if this made a difference.
I am looking for any suggestions on a different method or perhaps someone to tell me that the raid controller or some hardware isn't supported. I did install ubuntu-10.10-alternate-amd64 on my flash drive, but fail to get past detecting my CD-ROM drive since it's not plugged in. If this method is viable, I will plug it in. I also watched the ..... video were a guy creates Raid 0 with the alternated CD, but it wasn't a dual boot and didn't use a raid controller from a MB.

I have a Windows XP pc that has become corrupted and I have a image of the drive that I want to restore, however Drive Image won't allow me to restore to the main system drive. I was wondering if it is possible to use the Live CD and then do the restore through Ubuntu. I know it's probably a long shot but thought I'd ask anyway.

I performed an install using the 5.0.6 amd64 netinst cd on a dual opteron server with an Areca ARC-1110 4-port SATA hardware RAID card. I have 2 250GB drives set up as RAID 1. The debian install saw it as only one drive, just as it should. Install went smoothly, but on reboot, the system would not load.
I did some research and tried a couple of things with no luck. Like adding a delay in the grub command. It jus sits at loading system for a while then times out and loads busy box. Just to check things out, I booted into an Ubuntu live-cd and mounted the volume. The file system is there and all of the necessary files. How to use one of these cards successfully?

I had ubu 904 and vista installed on an 80gb drive, i had a spare 80gb drive also. I setup a raid0 config in my bios, then installed ubu9.10 onto it. All was fine until the very end, and then it said grub failed to install.
So i rebooted, and im left with a blinking cursor. How do i install grub? Ive installed ubu a few times now and never had an issue so now im lost.

I am attempting to install Maverick on an older pc. It has (2) mirrored 153 GB SATA drives. I set aside 33GB for a linux partition, by shrinking the partition in Vista.
Choosing to "Install along side windows" is not an available option. I can only choose use who disk, or use empty area. I choose use the empty area, and the Ubiquity installer gets hung up when attempting to format the empty space as EXT4. When I scroll up on the output I notice some error messages referencing NTFS. When I use Gparted it shows a possible problem.
Quote:

Probably /etc/mtab is missing. It's too risky to continue. You
might try an another Linux ditro.

The following list of software packages is required for ntfs file system support: ntfsprogs.
I ran chkdsk /r on the Vista partiton, in case there was a problem there. The issue still persists.

I newly installed debian squeeze with software raid. The way I did was, as also given in this thread.
- I have 2 HDD with 500 GB each. For each of them, I created 3 partitions (/boot, / and swap)
- I selected the hard drive and created a new partition table
- I created a new partition that was 1GB. I then specified to use the partition as a Physical Volume for RAID. and used for /boot and enabled bootable.
- Created another partition, which is of 480 GB, and then specified to use the partition as a Physical Volume for RAID. and used for /.
- Created another partion and used for swap
Then RAID configuration:
Through Configure RAID menu -> create MD device ->
(2 for the number of drives, 0 for spare devices)
Next select the partitions you want to be members of /dev/MD0. I selected /dev/sda1 and /dev/sdb1 (for /boot)
Next select the partitions you want to be members of /dev/MD1. I selected /dev/sda6 and /dev/sdb6 (for /)
And no RAID for swap partitions
'Finish Partitioning and write changes to disk' --> Finish the rest of the install like normal. Everything is ok now, except I am not sure how to test my raid config. When I pull the power of the HDD, it only boots from one disk. I read in some forum that I may have to install GRUB manually on the other. In Debian Squeeze, there is no grub command. Not sure how to make my software raid bootable from both disk. I configured /boot partitions of both disks to be boot=yes. Not sure whether that is ok.

I wanted to implement raid5 such that one partition is from my laptop's hard disk and others from other hard disks. After making one partition a raid partition, I rebooted the system. The computer stopped mid-way during booting, and brought me to the shell. On typing fsck -p, it told me an unexpected error occured in the partition which I had made for raid. Is there some condition that we cannot boot from a disk containing one of the raid partitions ?

i have been working with computers since the age of 11 "22 now" and have taught myself everything i know, from computer repair & networking to Web design, music production and Graphics design, using programs like photoshop, dreamweaver, sony acid, i learned it all myself, anyways that's just a little insight!!!
OK so here is my problem, i have an OLD P4 2.8 GHZ PC with 512MB ram, last year i was able to burn i believe fedora 9 to a CD and install it on this PC before i removed the drive to use as an external drive. "Dont know where the CD went"
I just recently purchased a 40GB hard drive and am looking to reinstall Fedora 14 on this P4 PC, i want to use this PC as a HTPC just for internet, ..... and stream videos, maybe some internet games etc etc, my problem is my main PC cant burn any cd/dvds due to the Drive's being burned out from burning xbox games at 4x on a regular basis, the PC i want to install Fedora on only accepts CD's and even then it barely reads anything!!
Now that you know my situation i want to know if i can take the 686MB 32bit iso image and put it on a 2GB usb drive and boot/install it to the HD that way on my old P4 PC, i want Fedora 14 as my main desktop, no partitions or walk arounds. If this helps the mobo on that OLD pc with the P4 is a p4vmm2 v5 i believe the p4 is 2.8ghz, ram is 512mb and i was able to install a 64mb nivida card agp 4x over the stock 32mb agp card it came with!
Last year windows xp was sketchy on it, i installed i think Fedora 9 and it ran great, but at that time it was a 120GB maxtor ide, and i decided to use it as an external drive for my main pc to back up alot of goodies, in the end the drive just randomly stopped working and just a few faint clicking sounds before it died. The current hard drive i will be installing on this P4 P4VMM2 mobo is a 40GB Seagate 7200. In the end do you think i can do a HD install from a USB stick with this P4VMM2 MOBO with a 40GB Seagate 7200 HD.
