Ubuntu Installation :: Upgrading To RAID 1 Without A New Install?
Feb 21, 2010
I already have a 300 GB SATA drive with Ubuntu 8.04 installed on it. It is currently running off my mobo's onboard SATA 1.0 Raid Controller. I recently purchased a SATA 2.0 Raid PCI controller that I will be putting in the computer and 2 new 750 GB Western Digital Caviar Green Hard drives. I wish to add the two drives in a Raid 1 configuration to store all my Pictures, Files, and Movies on. Every instruction and tutorial I can find on setting up Raid on Linux assumes you are performing a fresh install on Linux and gives no tips or instructions for current installations. I already have Ubuntu installed and do not wish to have to reinstall it. I want to leave my installation on the 300 GB drive and just add in the 2 750GB drives for storage.

I really want Python 2.6, which is not part of the standard Hardy packages. I just tried installing the Python 2.6 Linux distro direct from python.org. While I didn't see any error messages during the installation, I'm still defaulting to Python 2.5, and 2.6 installed to a different folder than 2.5.
A secondary wish: I would also like GROMACS 4.0 instead of 3.3. Again, Karmic has it as standard, Hardy doesn't.
I'm running dual hard drives in a software RAID1 configuration. My system is Linux only, so I have no Windoze compatibility issues to worry about.
Still, I've gathered that upgrading in the presence of RAID is different, and more problematic, than a standard upgrade.

I'm upgrading my PC by setting up a (fake) RAID 1 array. I've backed up my old hard drive using Clonezilla and tried restoring it while the array is active. However, I can't seem to fix the bootloader. The Ubuntu 11.04 LiveCD doesn't see the RAID array.
I have an ASUS M4A88T-M/USB3 motherboard that uses Advanced Micro Devices RAID option ROM utility to manage the array.

Building an Ubuntu file server that would be running software RAID5. While I think I have most of it figured out, I'm still a bit fuzzy about this: what happens if I trash or otherwise have to re-install my OS (because I decide to upgrade to a newer version, switch distros, or whatever)? Would the new OS be able to "see" that there was a RAID5 array on the disks and make use of it? Or would I for sure lose all of the data on the array?

Ran 'do-release-upgrade -d'on my server running Hardy.No problems during the upgrade.Rebooted after the upgrade completed, and I was presented with the new plymouth screen. This sucks for servers.It sat there displaying the logo for ~5 minutes.Hit CTRL+ALT+F1 through F8 and didn't see anything on the virtual consoles.Finally figured out that I had to hit ESC on the plymouth screen to actually see what was going on.It said /dev/sdi1 had problems along with /dev/md0.It sat there forever with no fsck status and no HDD lights blinking.
SysRq+REISUB and tweaked the boot parameter to remove 'quiet splash' and appended 'S' for single-user mode.Got the attached screenshot.The box has been sitting like this for ~15 minutes.Not entirely sure what to report a bug against at the moment. Plus the somewhat-new requirement of running 'ubuntu-bug' is pretty retarded in this situation. (Yeah, I know I can add some string to the URL to get around it.Why is it such a pain in the *** to report a bug?)I'm going to do some more digging to try and find out what is dying during boot.The new boot process is a bit of a mystery to me still, so if anyone has pointers or any devs want more detailed information,

I'm a relatively new user of Linux, I use Kubuntu 9.10, and I would like to know whether I need to make a clean install for upgrading to 10.4 (I know, stable isn't ready yet, but I'm impatient , and I want to prepare in advance) or I could do it in some way without losing everything I have installed? Or maybe it would be better to only upgrade to the newest version of KDE (I'm using 4.3.2 now)? Which one is easier and/or better? How is it done (Note: using KDE)?

I am currently running Ubuntu 9.10 on my desktop (no duel boots, its a single os on the computer) I wish to upgrade to 10.04 using the update manager, but the only thing that is stopping me is the new Grub.
Will the upgrade replace the current grub to the new one? because I DONT want it to change it, as previously I had issues with Grub 2 failing to install onto my hd. I just want it the same as it is now but with 10.04

I've just upgraded from ubuntu 9.10 to 10.04 64 bit, and everything went well except for the fglrx driver installation, which failed. I've checked the troubleshooting guide and tried to purge the drivers, with only partial success.
When i type dpkg -l '*fglrx*'
I get this,

I just performed a clean install of Ubuntu 10.04 on my flash drive, allocating a 6.5 GB persistence file. Of course, the first thing I did after booting from it was to run sudo apt-get update and sudo apt-get upgrade. After a lengthy install process, I was eventually notified that several packages failed to upgrade. I rebooted and tried again, still to no avail. Now, whenever I install a new package or attempt to upgrade with apt-get, I receive the following or a simmilar output:
Code:
Setting up fuse-utils (2.8.1-1.1ubuntu2.2) ...
creating fuse group...
udev active, skipping device node creation.
update-initramfs: deferring update (trigger activated)

I have an old Fedora machine setup to use Raid-1. I'm trying to install Ubuntu 10.04 Desktop on it, but the installer can't seem to override the raid partition. I have two 80GB drives, but the "Prepare disk space" screen only shows one 80GB partition called "/dev/mapper/isw_dfafhagdgg_RAID_Volume01". When I selected "Erase and use the entire disk", it gives me the error "The ext4 file system creation in partition #1 of Serial ATA RADI isw_dfafhagdgg_RAID_Volume0 (mirror) failed".
So I tried going back and specifying partitions manually. However, it only shows me the one device /dev/mapper/isw_dfafhagdgg_RAID_Volume01, and I can't delete it to get my original two hard drives, so I can recreate a RAID-1 setup. What am I doing wrong? I thought Ubuntu supported software RAID-1?

I have a system with RAid 0 with Windows 7. I want to load Ubuntu on a stand alone disk. I have two disks obviously for my raid o, two storage disks and an extra disk for ubuntu. I have tired to install unbuntu but upon start up I get an error on the disk. I than had to use grub to repair my mbr. My question is how do I make this work where I can have a dual boot system. I have been running ubuntu on my laptop .

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.

First off I'd like to say I'm very new to Ubuntu, so I'm still trying to learn.I have a K8 motherboard with an adaptec U320 SCSI card with RAID ability.To that card I connected two 15k RPM 35 GB Maxtor SCSI drives.For some reason I'm not able to install Ubuntu 9.10 onto these drives with both drives in RAID 0.With both drives separately configured Ubuntu doesn't even see them.I have by the way run Windows XP and 2000 succesfully on these drives in Raid 0 configuration.I set up the array in the card's bios as bootable with write cache enabled.The system's bios sees the array as the array to boot from.Ubuntu (both standard and alternate) sees the array and I have tried to install Ubuntu on it by manually partitioning it or having me guide it with or without LVM.I tend to delete and rebuild the array between attempts so I have a clean slate to start from every time I try.
I have no other drives (except the CD of course) installed on this computer.The whole installation goes very well untill the end where I get a message that it could not install the boot loader (grub?).Every single time I've tried to install Ubuntu in all sorts of ways onto my RAID 0 array I have run into problems installing that boot loader, and I've tried that card and those disks in another computer as well.Tomorrow I'd like to try to manually set up the partitions with a small /boot partition on a standard hard drive with / on the array, but if somebody please has any idea's on how I might get it working without having to rely on another hard disk (which might not even work of course)

Recently I did a wget for DreamLinux 4beta6.3, which I now cannot burn to a disk. Another issue with linux in general being just a hobby. Why could a dev not set it up where you could just wget the upgrades for the main distro files themselves ?? We already do this when upgrading the apps, so why not the distro? Why could you not start at alpha, and just slap do a rolling upgrade into rc and beyond?
I understand the potential stability issues, but why can't we ghost the drive and hence have a backup on hand and then do this as outlined, and hence do a single install from alpha the distro's grave? I am wasting four months on "Setting Up" each install, only to wind up reinstalling again. This happens in every variation I have come across. Even in stable versions, the rolling upgrade just craps the install, and the major do overs hijacks all my data.

I'm running a triple-core AMD 32-bit CPU, with two matched hard drives in a software RAID 1 configuration. The system is single-boot, running Hardy only. I have no Windoze compatibility issues to impede me. In some recent posts, I discussed my desire to add a few non-standard applications to Hardy. Well, it hasn't been working for me. I've succeeded in breaking my standard Python 2.5 installation, and the Python 2.6 that I was trying to install is also broken. After asking questions in various Python forums and not getting answers, I'm starting to think about my alternatives.
I have backed up all my hard-drive data, and downloaded Karmic. I'm running from the Live CD. I am considering a clean install, though of course I would save a lot of time if I could just upgrade.
Before I leap, I see one possible problem: Karmic has failed to mount any of my hard drive partitions, as RAID or otherwise. Should I worry? When I upgraded from Dapper to Hardy on an older (non-RAID) machine, I recall that my hard disk mounted from the Live CD just fine.
Also, am I correct in understanding that Karmic is RAID-aware right out of the box? I'm wondering if I'll have to set it up manually again. That took me a while. By the way, I didn't set up separate partitions for boot, root and home (stupid me). Can I do that after the fact during an upgrade?

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 need to add the LSI drivers for the 9750 RAID controller during the install. These drivers are not included in 10.04 (or 10.04.1) and I need to install onto the RAID device I've created. LSI provides the drivers and instructions here - [URL]
Here are my steps, with the drivers on a USB drive -
Code:
Boot from the installation CD and select Install Ubuntu Server.
Press CTRL+ALT+F2 to switch to console 2 while Ubuntu detects the network.
# mkdir /mnt2 /3ware
# mount /dev/sda1 /mnt2
NOTE: LSI drivers are at /dev/sda1, via USB
# cp /mnt2/9750-server.tgz /3ware
# cd /3ware ; tar zxvf 9750-server.tgz
# umount /mnt2
* Remove the USB flash before insmod command *
# insmod /3ware/2.6.32-21-generic/3w-sas.ko
Press CTRL+ALT+F1 to return to the installer. Continue the installation as usual. Do not reboot when the installation is complete. Press CTRL+ALT+F2 to switch to console 2 again.
# cp /3ware/2.6.32-21-server/3w-sas.ko /target/lib/modules/2.6.32-21-server/kernel/drivers/scsi
# chroot /target
# /sbin/depmod -a 2.6.32-21-server
# update-initramfs -u -v
# exit
Press CTRL+ALT+F1 to return to the installer. Reboot to complete the installation. There are no errors, but after I reboot I just get "GRUB" in the upper left corner, nothing else.

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'm trying to switch to a new RAID5 array but can't get it to boot. My disks:/dev/sda: new RAID member
/dev/sdb: Windows disk
/dev/sdc: new RAID member
/dev/sdd: old disk, currently using /dev/sdd3 as /
The RAID array is /dev/md0, which is comprised of /dev/sda1 and /dev/sdc1. I have copied the contents of /dev/sdd3 to /dev/md0, and can mount /dev/md0 and chroot into it. I did this:
Code:
sudo mount /dev/md0 /mnt/raid
sudo mount --bind /dev /mnt/raid/dev
sudo mount --bind /proc /mnt/raid/proc
[code]....
This completes with no errors, and /boot/grub/grub.cfg looks correct[EDIT: No it doesn't. It has root='(md/0)' instead of root='(md0)']. For example, here's the first entry:
Code:
### BEGIN /etc/grub.d/10_linux ###
menuentry 'Ubuntu, with Linux 2.6.35-25-generic' --class ubuntu --class gnu-linu
x --class gnu --class os {
[code]....
However, when I try to boot from /dev/sda, I get:
Code:
error: file not found

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 have created a system using four 2Tb hdd. Three are members of a soft-raid mirrored (RAID1) with a hot spare and the fourth hdd is a lvm hard drive separate from the RAID setup. All hdd are gpt partitioned.
The RAID is setup as /dev/md0 for mirrored /boot partations (non-lvm) and the /dev/md1 is lvm with various logical volumes within for swap space, root, home, etc.
When grub installs, it says it installed to /dev/sda but it will not reboot and complains that "No boot loader . . ."
I have used the supergrubdisk image to get the machine started and it finds the kernel but "grub-install /dev/sda" reports success and yet, computer will not start with "No boot loader . . ." (Currently, because it is running, I cannot restart to get the complete complaint phrase as md1 is syncing. Thought I'd let it finish the sync operation while I search for answers.)
I have installed and re-installed several times trying various settings. My question has become, when setting up gpt and reserving the first gigabyte for grub, users cannot set the boot flag for the partition. As I have tried gparted and well as the normal Debian partitioner, both will NOT let you set the "boot flag" to that partition. So, as a novice (to Debian) I am assuming that "boot flag" does not matter.
Other readings indicate that yes, you do not need a "boot flag" partition. "Boot flag" is only for a Windows partition. This is a Debian only server, no windows OS.

I am doing a new install and have 4 drives (2x500Gb and 2x2Tb). What I want is the OS on the 2x500Gb and the data on the 2Tb drives. The idea is to make the 500's one RAID 1 set and the 2Tb a RAID 1 set. I think the installer is trying to build the RAID set for the OS but the root is looking like a RAID 0 rather than 1. Is there some way to specify?

I'm running Karmic Server with GRUB2 on a Dell XPS 420. Everything was running fine until I changed 2 BIOS settings in an attempt to make my Virtual Box guests run faster. I turned on SpeedStep and Virtualization, rebooted, and I was slapped in the face with a grub error 15. I can't, in my wildest dreams, imagine how these two settings could cause a problem for GRUB, but they have. To make matters worse, I've set my server up to use Luks encrypted LVMs on soft-RAID. From what I can gather, it seems my only hope is to reinstall GRUB. So, I've tried to follow the Live CD instructions outlined in the following article (adding the necessary steps to mount my RAID volumes and LVMs). [URL]
If I try mounting the root lvm as 'dev/vg-root' on /mnt and the boot partition as 'dev/md0' on /mnt/boot, when I try to run the command $sudo grub-install --root-directory=/mnt/ /dev/md0, I get an errors: grub-setup: warn: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea. grub-setup: error: Embedding is not possible, but this is required when the root device is on a RAID array or LVM volume.
Somewhere in my troubleshooting, I also tried mounting the root lvm as 'dev/mapper/vg-root'. This results in the grub-install error: $sudo grub-install --root-directory=/mnt/ /dev/md0 Invalid device 'dev/md0'
Obviously, neither case fixes the problem. I've been searching and troubleshooting for several hours this evening, and I must have my system operational by Monday morning. That means if I don't have a solution by pretty early tomorrow morning...I'm screwed. A full rebuild will by my only option.

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.
