Ubuntu Installation :: Conemplating A Karmic Install With Software RAID 1?
Jan 26, 2010
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?

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 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've been trying to get Grub 2 to work on a desktop system I'm trying to install Karmic Koala on. It's currently got two similar hard drives, which I've partitioned into a small /boot partition and the rest as a large general partition. Both are fd (linux software RAID) types. I boot from the Ubuntu live CD then create the RAID arrays as RAID 1 (requires installing mdadm to work). Then I start the arrays and begin the install.
I select manual partitioning and create the first RAID array (/dev/md0) as an ext4 /boot. The second array (/dev/md1) requires a new partition table. I then partition it as 20G for /, 2G for swap and the rest as /home, giving me /dev/md1p1, /dev/md1p2 and /dev/md1p3. When the install finishes, I mount the various partitions in /mnt (for /dev/md1p1) and below, including binding /dev and /proc. Then I chroot and install mdadm in the new system. I update grub, re-install it on /dev/sda & /dev/sdb then update the initramfs.
A quick reboot and things go wrong... Grub boots me into a recovery console. Apparently it can't see the partitions in the second RAID array. how to get Grub 2 and/or mdadm to work in this situation? I know that apart from the RAID, the above process worked to allow me to set up a Grub 2 boot on an antique laptop with an incomplete install.

Ubuntu Karmic worked fine on my computer when it was first released but now doing a fresh install on my computer is totally impossible. The hardware is all the same.If I attempt to install from Live mode - karmic freezes when it's configuring Apt and ubiquity-dm crashes when installing direct from boot.I have switched to Mint but I would like to go back go to Ubuntu.

Am running karmic on a P2-350 Mhz with 256 Mb RAM. Yes, I know this is an old computer, but it has been very good, performance wise, since versions earlier than 8.x I think.
But now, after a fresh install of karmic, it is very slow at everything. Checked system monitor and CPU is constantly running at between 95% and 100%

I have looked many places for good tutorial on configuration of amanda client with Karmic, but none of them are good enough. I basically got following message no matter what I change in Client side.
1. I am using 64-bit Ubuntu Karmic client with 2.5.2p1 amanda-client with xinetd.
2. The user is backup, group is backup.
3. The config file is located at /etc/amandahosts, and /var/backups/.amandahosts and /var/lib/amanda/.amand ahosts using soft link to the /etc/amandahosts file.
4. /etc/amandahosts file have following line.192.168.0.14 backup amdump.The 192.168.0.14 is server IP address.

I'm a big convert on using Ubuntu on my x86/x64 machines.I have a nice IBM Intellistation 185 Power PC (ppc) with dual 970 processors and 8gb of ram (and 3 SCSI 300 MB drives).I tried to install Ubuntu 9.10 on it (the PPC distro) and it gets to the boot prompt, asks me how I want to install (I can choose "live" or "install", etc..). No matter which option I choose (I've tried them all) it hangs after trying to start the kernel at "returning from prom_init".
NI've also tried other distros to see where that got me - Debian does the exact same thing as Ubuntu (which makes sense). Yellow Dog Linux actually will install and run fine(I'm writing this from Firefox 3 in YDL). Since YDL works, I'd think that a version of Debian/Ubuntu should be able to work.Any ideas on how to debug this and find out why Ubuntu won't install (or even run the Live CD?)

I want to install Ubuntu to HDD via USB drive but I can't see my HDD. Only the USB drive is there. I don't have any CD left to burn the ISO, so USB drive is my only choice.

I bought a magazine "Ubuntu User" that comes with the 9.10 DVD (32- & 64-bit) to avoid heavy download.
1. What is the biggest benefit of the DVD versus the CD ? Having more software on the disc right ? But how can I install additional SW without downloading ?
2. I want to install a Home Server from the DVD but I don't know how to select the server edition to install ? Do I still need to download the CD image for the server edition ? I want to be able to select one or more of the automatic server installation scripts e.g. LAMP.

I just installed Karmic Koala on one of my hard harddrive. The other disk has Windows XP. Previously I had a working dual-boot setup, but after problems with Ubuntu I reinstalled it. On booting, I get the following:
Code:
Grub Loading stage1.5
Grub loading, please wait...
Error 2
There is no Grub menu which might allow me to drop to a Grub prompt and evaluate. This occurs whether I boot with the Ubuntu harddrive or re-set the BIOS to boot with the Windows harddrive. If I boot with a LiveCD, I see that both my Ubuntu and Windows harddrives exist and are readable; the Ubuntu was indeed wiped clean and reinstalled; the issue is with the boot process. How can I set this up to boot?

On my iSCSI booted server, the standard Karmic Server install CD installs a system that won't boot.This is caused by a bug in the initscripts. This bug is solved in an update of this package. How do I get the updated version of the initscripts package on my install CD?

Has anyone tried to install Karmic on a laptop that has HP's new Linux on a chip OS installed? I think it's a scaled down Splashtop desktop and at least a portion of the OS is hardware based. I sure wonder what would happen if/when I try to install grub and Ubuntu.

i have Karmic installed with Wubi inside a Vista NTFS filesystem. Yesterday i did an apt-get dist-upgrade and Karmic never booted again. It won't even show the grub kernel list, it just shows some really quick text that vanishes before i can even figure out what it is and then drops to some sort of grub shell and then i can't figure out what to do.
I could boot a livecd and mount my karmic install and everything seems fine, the filesystem is clean and all that. But how do i fix it so it can boot again?
Does anyone here know wtf happened? Was there a bad upgrade or something?

I've never tried installing any other operating system on my desktop so I'm not sure if it's a 9.10 bug (probably not), but whenever I choose any of the options after the ubuntu cd has been loaded at startup it goes to a black screen with the underscore at the top, and promptly reboots. At this point in time I can just boot back into windows or get to the same selection screen off of the cd.I've tried burning 3 seperate cd's and at the moment and trying to boot them on my laptop (but not working... hrm). I'm thinking about redownloading the iso in a couple minutes.

I installed Ubuntu9.10 on a USB hard drive attached to my laptop. Laptop has pre-installed XP in the in-built hard-drive. Point to be noted is that my hard-drive is protected via encryption software called Pointsec.
The installation of Ubuntu on the USB hard drive went through fine and I'm able to boot Ubuntu from it.
But now the problem is, GRUB2 fails to detect the Windows XP installation.
Can someone tell me how I can force GRUB2 to boot Windows XP from hd0,0?
The GRUB1 way of configuring /etc/grub/menu.lst does NOT seem to work with GRUB2.

I have an etch-based Xen server that has several Xen domU's on it. All the domU's are etch or lenny based, but I'd like to install a karmic guest. I use xen-tools to install my domU's - e.g., xen-create-image --debootstrap <etc.>After much googling, I've found bits and pieces of info that have gotten me closer to the goal, but the debootstrap script I have is for hoary (I think etch came with this), and I'm pretty sure this won't work.
If you have been able to successfully install a Karmic guest on an etch or lenny host, I'd be very grateful for pointers.

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 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 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)
