Ubuntu Installation :: 10.04.2 - Alternate For RAID Support
Apr 8, 2011
I am trying to install ubuntu 10.04.2 onto a computer (alternate for RAID support). This is a fresh install - I am formatting all drives. Partitioning, setting up RAID, and the beginnings of the instilation appears to go fine. But part way through it "sticks" at a screen asking for a "media change" to the CD which is already in the CD tray. Nothing I do appears to stop this (i.e. clicking 'go back', removing/inserting the CD, etc). I've even tried unplugging the network connection.
The specific error reads:
Code:
[!!] Install the base system
Please insert the disk labeled: 'Ubuntu 10.04.2 LTS _Lucid Lynx_ -
release amd64 (20110211.3) in the drive '/cdrom/' and press enter.
Media change
<Go Back> <Continue>
How do I get past this point? (and yes, the red text is in red).

UPDATE: decided to reinstall and run the partitioner to get rid of the raid. Not worth dealing with this since seems to be lower level as /dev/mapper was not listing any devices. Error 15 at grub points to legacy grub. So avoiding the problem by getting rid of raid for now. So ignore this post. Found a nice grub2 explanation on the wiki but didn't help this situation since probably isn't a grub problem. Probably is a installer failure to map devices properly when it only used what was already available and didn't create them during the install. I don't know, just guessing. Had OpenSuSE 10.3 64bit installed with software raid mirrored swap, boot, root. Used the alternate 64bit Ubuntu iso for installation. Since partitioning was already correctly setup and the raid devices /dev/md0,1,2 were recognized by the installer, I chose to format the partitions with ext3 and accept the configuration:
/dev/md0 = swap = /dev/sda1, /dev/sdb1 = 2Gb
/dev/md1 = boot = /dev/sda2, /dev/sdb2 = 256Mb
/dev/md2 = root = /dev/sda3, /dev/sda3 = 20Gb
Installation process failed at the point of installing grub. It had attempted to install the bootloader on /dev/sda2 and /dev/sdb2. I moved on since it would not let me fiddle with the settings and I got the machine rebooted with the rescue option on the iso used for installing. Now, I can see the root partition is populated with files as expected. dpkg will list that linux-image-generic, headers, and linux-generic are installed with other supporting kernel packages. grub-pc is installed as well. However, the /boot partition or /dev/md1 was empty initially after the reboot. What is the procedure to get grub to install the bootloader on /dev/sda2 and /dev/sdb2, which represent /dev/md1 or /boot?
Running apt-get update and apt-get upgrade installed a newer kernel and this populated the /boot partition. Running update-grub results in a "/usr/sbin/grub-probe: error: no mapping exists for 'md2'". grub-install /dev/md2 or grub-install /dev/sda2 gives the same error as well. Both commands indicate that "Autodetection of a filesystem module failed, Please specify the module with the option '--modules' explicitly". What is the right modules that need to be loaded for a raid partition in initrd? Should I be telling grub to use the a raid module?

I am trying to install Ubuntu on a nvidia board which, based on the forums I have perused, is a FAKERaid chipset. Originally I tried to install according to https://help.ubuntu.com/community/FakeRaidHowto to no avail. I gave up and am resorting to breaking down my raid setup (thus losing my Windows XP installation) and using Linux's software raid (which seems to be the recommended method) with the Alternate CD install.
I went in to the bios and completely disabled my board's RAID function. I then followed the instructions here: https://help.ubuntu.com/community/In...n/SoftwareRAID , except it popped up with a window advising me "one or more serial ATA RAID configurations have been found. Do you wish to activate these RAID devices?" which that page didn't mention. I believe I selected "Yes". Setting up the partitions I made (from beginning of disk to end of disk) a RAID1 200MB /boot partition, a RAID0 / partition (90GB?), free space not set up in RAID (approx 20GB for each SATA drive to later install Windows on [if that's even possible]) & then the SWAP partition 2GB at the end of one of the disks (is it OK that this one wasn't in RAID?).
The installation completed, as far as I can tell, without a hitch. Except also of note: my network card doesn't work in the installer (gives an error message about unable to configure dhcp) so i'm not connected to the internet. Then I restart and the following appears: grub loading: error: biosdisk read error. Followed by what appears to be the Ubuntu loading splash (just a small white shape in the middle of the screen), and then:

I am going to setup a new Ubuntu 10.04 using RAID 1 soon. Installation will be via the alternate CD. Older distributions required manually installing Grub to the second drive, to boot if the first drive fails. I found different statements about how this is handled since 9.10.e.g.
Quote:
Install GRUB boot-loader on second drive (this step is not need if you use Ubuntu 9.10)
or
Quote:
installing GRUB to second hard drive depending on your distribution
> grub-install /dev/md0
or
> grub-install /dev/sda
> grub-install /dev/sdb
is Grub2 automatically installed in all RAID drives using alternate CD 10.04 like executing sort of "grub-nstall /dev/md0" during the installation ?

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 am running Windows 7 and wanted to install VMWare and Ubuntu on it. So I downloaded VMware and the Ubuntu install files but I got stuck on the Language prompt. So I researched and downloaded Ubuntu alternate iso file and the install went fine.
I now launch VMWare and get a prompt for username and Password which I enter.

Actually, thats a lie. It works on the initial screen (where you can select how you want to install via command line or text based etc etc).But whatever option i select from there it loses the keyboard.The first screen (asking for keyboard layout) just sits there on english but i am unable to advance. Its as if my keyboard is unplugged (has LED backlights and they turn off as soon as it hits this screen so im guessing its USB driver related).I wanted the alternate to do drive encryption but it doesnt seem to want to know. Normal CD works fine btw.

have been trying for many hours to install Ubuntu 9.10, on a system that already had 9.10 installed on it at one point (so I know it should work!) I am using an alternate install, from a USB thumb drive. I use the alternate so I can encrypt the hd. Everything goes smoothly until I am to select extra packages to be installed. The only package I select is the ubuntu-desktop, and around 80% progress, or so, it fails. I then try and complete the base install, and then login to the command prompt and install there:
sudo apt-get install ubuntu-desktopIt then requests the Ubuntu disc, which of course I don't have. It has a landline internet connection. Do I need to configure something to tell it to look to the mirrors to find the desktop? Or, should it have been included in my iso image originally

I've tried the Universal USB Installer, but that doesn't support the alternate iso. And if I select the regular desktop one, it screws up the installation when I try to boot.
Unetbootin gives me this error during the cdrom process. It says it can't find copy files from cdrom and stuff. Well of course, there's no cdrom...

I'm currently using Empathy as per 10.04's standard, but I need a new Yahoo client.
I've used Gyachi in the past, and it was great and all, but it's gone now. It's been missing from it's repository for a long time. (If that doesn't make any sense, what I'm trying to say is that it won't download from it's source, in the way that you usually install it.)
I've also heard about Yux, but out of curiosity, is there anything better? Empathy is missing some basic features, like webcam (understandable) to "message all in group"

and a HD raedon 4650 AGB 1Gb Grafics Card
I have tried to install Ubuntu with this CD and it gets past the keyboard detection part and then it tells me i need to get the CD ROM drivers via removable media, i know this is a problem with ubuntu 10.04 because i can install just fine a 8.04 ubuntu.
i don't know what to do.I have tried to install from a USB but my comp is too old for that, i know its not the specific cd because i'v used about 5 different brands of cd just to see if it was the cds i was uesing,
I would just upgrade from 8.04 to 10.04 but i get to the dbus part and the comp starts to run really slowly and eventually colors just show up, i left it for an hour to see if they would go away and fix but they didn't. Iknow my comp CAN run 10.04 because i have done it before, but i uninstalled and now i can't seem to get it to work again.
P.S. i have tried the live cd, same effect.

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]
I was able to examine the disks though:
Code:
root@127.0.0.1:/etc# mdadm --examine /dev/sdb2
/dev/sdb2:
Magic : a92b4efc
Version : 00.90.00
code....
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 can't boot to Windows XP after recently installing Ubuntu (Ubuntu boots fine). The error that comes up (straight after selecting XP) is that it can't find "system32hall.dll".
Reason for the problem: Ubuntu is looking at the old, corrupted version of XP that I have. The 'real' version is on another partition, for reasons too lengthy to explain. Note: neither of these partitions were touched when installing Ubuntu - I placed Ubuntu in the pre-existing partitions I had setup when installing previous versions of Linux (last was Mandrake 8.)
Now, I can understand why it is looking at the old version, because it is on the first partition of the hard drive, "dev/sda1", the new version is on "dev/sda3" (nomenclature according to Ubuntu, obviously).
Question: How do I point the config file to sda3? I have tried setting root to "hd0,3" and "hd3,1" with no luck. Original code is below:
Code:
### BEGIN /etc/grub.d/30_os-prober ###
menuentry "Microsoft Windows XP Professional (on /dev/sda1)" {
insmod ntfs
set root=(hd0,1)
[Code]....

Halfway through upgrading from 9.10 to 10.04 (i386 desktop) using the Alternate CD, you are prompted to insert "Ubuntu 10.04 LTS _Lucid Lynx_ - Release i386 (20100429)".Luckily, I'd already burnt a full installation CD so swapped this and the run continued for a moment. It then asked for the Alternate CD again (20100427.1).If you haven't got a full install CD handy before you start, you may not be able to complete the upgrade.

Today I decided to replace my 9.04 install with 10.04. (I did this on a separate hard disk.) As I am a big fan of LVM I used the 'Alternate' install CD. Everything installed fine.
However, upon booting I observed two things: firstly there was no grub menu. No countdown timer, no menu. Just a flickering cursor. After 15 seconds or so I got a message telling me that:
Code:
/dev/mapper/bromine-root (My root partition.) does not exist and that it had given up waiting. Finding this kind of strange I tried the alpha of 10.10 --- same again. Hence I have two questions: firstly, where did the nice grub menu go; secondly, what is wrong with LVM and grub these days? At the initframfs prompt I am thrown to there are some LVM utilities and they appear to show my volumes.
Switching back to my old pair of hard disks and everything works as expected (i.e, the hardware is fine and supported by Linux.)

How can one create an alternate disk or boot path on a ubuntu server? I have a new server running 9.10 and have a full backup of an old server which had all the configuration and installed softwares, etc. Instead of trying to reinstall everything and configure it the way it was, I was thinking of adding another disk to the server, mount it and then hopefully be able to boot it from there. I don't have any LVM or mirroring setup but was hoping if I can specify a secondary boot path when the server boots up, if it fails I should be able to go back to the current one.

I downloaded the Xubuntu 10.04.2 Alternate Install CD ISO file from http://mirror.anl.gov/pub/ubuntu-iso...10.04/release/
When I checked the md5sum of the downloaded file, however, there was a mismatch.
The md5sum given at both http://mirror.anl.gov/pub/ubuntu-iso...elease/MD5SUMS as well as https:[url].... is 209cfc88be17ededb373b601e8defdee *xubuntu-10.04.2-alternate-i386.iso but running the command,
Code:
md5sum xubuntu-10.04.2-alternate-i386.iso generated the following, obviously different checksum for me:
098674ad5a59f0115030c5c0c3973899 xubuntu-10.04.2-alternate-i386.iso
(It also took unusually long to generate the checksum- around thirty minutes.)
Is it possible that the file was corrupted or tampered with on the server?

I tried searching for the MD5 checksum page for 11.04 64bit, both the alternate download version and the desktop download version and found it, but that site seems to be down right now. I also got the feeling that that website was for the daily build and may not have the MD5 checksum for the release version. What the MD5 checksum is for Ubuntu 11.04 64bit: alternate download and desktop versions.

The MD5SUM file on the ubuntu-11.04-alternate-i386.iso disc is wrong. It has an incorrect checksum of 2 files and 18 that are missing or have incorrect names. I'm checking these from a Windows box but that really shouldn't matter. The two incorrect hashes are:
Code:
543f56d91223039621db4cf3b50dde37 ./install/netboot/ubuntu-installer/i386/pxelinux.cfg/default
0ae389801f547ccf19bd6f63c0ab3b7d ./install/netboot/ubuntu-installer/i386/pxelinux.0
I'm showing an MD5 of D41D8CD98F00B204E9800998ECF8427E for both files...
These are the files which appear to be missing or misnamed (the ones I checked appear to be on the disc but are named incorrectly):
Code:
./pool/main/x/xserver-xorg-input-synaptics/xserver-xorg-input-synaptics_1.3.99+git20110116.0e27ce3a-0ubuntu12_i386.deb

Alternate CD on USB - Natty not mounting Encrypted Volume I get initramfs prompt. I have a Dell Inspiron Duo. I've tried to install Natty i386 and AMD64. I set my / (root) and swap under LVM under an encrypted volume. Used manual partitioning. But after reboot, I successfully enter the passphrase, swap and root are not mounted.
Now, I've had this working with 10.10. System seemed a little quirky after the upgrading it to Natty. So, I wanted a fresh install. Used Unetbootin to run ISO from USB and also from one of my other partitions. I've tried installing at least 10 times, some repeat, some variations.
