General :: RAID And Grub 2 On Ubuntu Karmic Koala (installation)
Feb 11, 2010
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.
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 have a laptop with Karmic Koala in dual boot with Lenny. I need to reinstall Lenny however if I do that I will loose Karmic Koala in the grub screen because of the new version of grub that comes with Karmic Koala. Which means that I will need to reinstall Karmic Koala after Lenny so that they both appear in the grub screen at startup. If I reinstall only Lenny is it possible to use Gparted to change the boot back to Karmic Koala and have them both in the grub screen again? Or is there another way around it?
I recently installed Karmic Koala server edition, and then did the 'apt-get ..install' for the desktop gnome, but now I'm not sure what to do to get my gui to show. I am stuck at the termanal type command line, it's asking for a sudo comman. I know a few 'sudo' commands, but I really need the gui.
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 am having problem in grub2 fails to boot the system. I get the error:
Booting from local disk... GRUB loading. error: no such disk System setup:
It's a Dell XPS400 PC with 160 GB HDD. I have a non-LVM, primary partition for the boot file system (/boot) of 200 MB. I also have seven logical volumes (LVM partitions): six for each of the /(root), swap, /home, /usr, /var and /tmp, and one vbox_win_xp_base as a raw disk for running Win XP in the Virtualbox. I went on to configure all these without rebooting the system in between. Later I also updated to the kernel version 2.6.31._20. Next day I decided to reboot my system. But then the bootloader (GRUB2 in my case) won't able to boot it and gives the error mentioned above.
i install ubuntu carmic koala, after that, my internet connection was not support with ubuntu karmic koala,,i'm using compaq cq40-337 tu.. how to setting the internet connection?
I've installed Karmimc Koala server edition, and I wanted the gui so I followed advice on a forum and did an apt get install gnome desktop etc. but don't know what to do next, all I see is a command line, no gui. I would even settle for just having web min so I could control my server from that, as I have read that servers are more vulnerable with a gui.....and my last ubuntu server got hacked, so I had to wipe out the hard drive and start all over.
I just upgraded from Jaunty to Karmic, but once I loaded Karmic and rebooted, my computer will not complete the boot up sequence and go into any desktop. It starts the initial boot sequence with the mouse appearing and then goes to the screen that looks like it has an atom cloud. After that, the screen goes black and the mouse-arrow turns into that white rotating wheel, but it stays that way. It never actually goes into any type of operation! I tried to go from the command line and find Lucid to overlay it on Karmic and hopefully solve the problem. It just looks like to me that several of the packages I downloaded through my upgrade manager were corrupted. My computer doesn't even seem to be acknowledging my password because it gives me an error 32:must be authenticated.
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 have 2 hard drives on my machine (1 with ubuntu & 1 with win xp) & would like to create a boot menu to select either at startup, but this isn't working. here is the order of how i setup my system:
1. installed win xp on drive1 2. disconnected drive 1 & installed ubuntu 9.10 on drive2 3. set ubuntu as master drive & win xp as slave drive
i've read about modifying menu.lst to get a boot menu, but as far as i can tell this is no longer valid in 9.10. i've also installed startup manager, which gives me a boot menu *but* when i select the win xp option at the boot menu, i get an error. i'm assuming this error is due to the fact that i am using 2 hard drives (instead of the more common 2 partition on 1 hard drive). Here is what my boot option says: Microsoft Windows XP Professional (on /dev/sdb1) Here is what commands run when I select this option:
drivemap -s (hd0) ${root} chainloader +1 Here is the error that results: ERROR: INVALID SIGNATURE
is it possible to get a boot menu with 2 hard drives using 9.10? it's worth mentioning that i am a brand new user to linux. p.s. the reason i didn't go for a partition on 1 hard drive from the start is that the ubuntu partitioner did not recognize any free space on my win xp drive.
Lately I have noted a decrease on the performance of my Ubuntu Karmic Koala 64 bits installation. It takes longer times to open applications and documents and sometimes the windows fade to grey and I have to wait. Can anyone give me some hint on where to start looking for a solution?
I currently use Karmic Koala (9.10) and want to upgrade to Maverick Meerkat (10.10). The thing is that Update Manager allows me to upgrade only to 10.04 (Lucid Lynx) but I cannot upgrade to Lucid Lynx because of a bug which freezes my keyboard and mouse. Also, upgrading first to 10.04 and then to 10.10 is quite time consuming. Can I upgrade directly to 10.10 from 9.10 without 10.04 acting as a mediator?
I had some problems with printing pdf on my HP 1020 (it was printing only text, but not figures or pictures). After reinstalling a few times, I realised that problem was not the driver, but the type of pdf format. Some pdf creator (like>cairo, or some creators for Windows) has format which can not be parsed on Ubuntu. Workaround is to 'print to a file' (postscript), save it somewhere and then print that new postscript document.
I could not keep this question from turning into a wall of text so I broke it up into these 4 sections.I have 2 monitors (DELL E228WFP and a DELL 2007FP) hooked up to a EVGA E-GEFORCE 8800GT 600MHZ 512MB 1.8GHZ DDR3 PCI-E Dual DVI-I video card. I would like to have the DELL 2007FP set up to the left of the DELL E228WFP and rotated into "portrait" mode^ with both screens sharing a common bottom edge.
This is ideal for reading PDF documentation or papers on one screen and then working on the second one.Steps Undertaken I installed the NVidia drivers (via sudo apt-get install nvidia-current) rebooted ran nvidia-xconfig then ran nvidia-settings. However, like many people, I could not get nvidia-settings to write to my config file despite having run it with kdesudo. Instead, I opened the file with Kate (using KDESudo) and then used the preview from nvidia-settings and just copy pasted it into the file and saved it like that. if I use TwinView I have both monitors working, but when I try to use krandrtray to rotate one of them, it is shown as one large monitor so I cannot rotate just the one I want rotated.However, if I set them up as separate X windows the second one is black and krandrtray only shows the main monitor. I am at a loss of what to try next.
I need a program which generates events when a file is moved, removed or its extended attributes are changed. I'm running Ubuntu Karmic Koala 32-bit desktop.inotify is the standard solution for such problems, but inotify cannot install a recursive watch, so the only option is to the equivalent of find on the filesystem, and add an inotify watch on each node. This is what e.g. inotifywatch does. This won't work for me, because my filesystem has 1 million files, and installing watches to all of them takes forever.
fanotify could work except that I would have to patch the kernel for that (I'm currently running 2.6.31-20), and maintaining patches to the Linux kernel is beyond my time commitment.I used to use rfsdelta (whose kernel module is similar to rlocate), but it just doesn't compile on 2.6.31, because it uses obsolete Linux security framework APIs.
I reinstalled Ubuntu on my HP pc-40 computer. I used to run Hardy Heron and am now running Karmic Koala. The cd drive which had had issues for a while, broke after finishing the install, when I tried to get the cd out.I dont know if this has anything to do with it, or if my computer is too old for Karmic Koala, or if possibly the harddrive didn't appreciate being overwritten a second time - but the graphics are not working well (small squares of previous windows linger in my present browser window*)everythin is much slower, and many applications come up without a border, or their windows cant be moved with the mouse.
To top it off, while I tried to fix a bug with the terminal (no border) and uninstalled it, I couldnt install it back. So no terminal, which really makes even a newbie like me sad.If I cant solve it in a few days I will probably try to install a smaller distro via USB - I think Slax can be installed straight to USB without a live cd?
I had been happily on Jaunty Jackalope until they stopped supporting it so I took the forced upgrade and it's HORRIBLE!
I feel like I'm back in Windows land. Within an hour of my first load I had my very first Ubuntu total-lockup. Just like Windows. In the 18 months I'd been using Jackalope I had not had a single crash. Not one.
It's slow, jerky, and has odd freezes. Just like Windows. Applications randomly stop working and die. Just like Windows.
Is there any way to fall back to Jackalope or is there any hope of them fixing Koala? 'Cause this is wretched.
I see there's another version out there...10.04.01.LTS. I'll try that. It can't be much worse.
I'm making a school project and need a ubuntu command line edition with low used space.Now I was able to download and install the Ubuntu 9.10 "Karmic Koala" Minimal CD.But the size is now total 626mb and packages installed around 300mb.I figured that the archived deb files were not deleted when installed.
I have read numerous posts about this subject, but being a novis in the Linux field, I cannot say that without explicit step by step instructions I am able to repair or tinker with anything under Ubuntu. In short, my sound has ceased to function. It did work for a period of time and suddenly no more. I have a 64 bit version of Ubuntu 9.1.
I am looking for the easiest way to get my workstation running with the needed services. At this time, these include SSHD and Music Player Daemon.
I ve installed both and they work when activated manually by sudo /etc/init.d/ssh start, or mpd respectively. But I don t have a clue as to how to start them up with an Upstart job?
Can a 32 bit karmic koala 9.10 support 4gb of ram. i donut want to get 64 bit because of the compatibility problems. so i am wandering can a 32 bit ubuntu run 4gb ram with it?
using 9.10 Karmic Koala I have a folder of JPGs. Rightclick on one, choose Open With F=Spot. A small window opens. Then a larger one, identifying the F-Spot program. Then everything goes away. Or I go to Applications/Graphics/F-SpotPhotoManager the same thing happens: small window, big window, gone.
On Dell Inspiron 9200, with or without accelerator for NVIDEA graphics. P.S. I would like to give 9.10 a chance. have gedit and browser open (browser with the forum message being edited), then do the following:
1.This example demonstrates one problem (unresponsive single click) Use the System-->Preferences-->Mouse
Click repeatedly on the light bulb at 1 second interval ---> result: often the light does not turn on. Result: it appears that the click event does not complete. I have noticed that a mouse-out will cause the click to complete (specifically as in 2. and 3 after a brief moment (hopefully before the drag and drop icon appears).
2. Click on any icon, submit button, close, etc. takes many tries.
3. Click on any icon, panel button, link, etc. if you linger a moment a floating icon (a drag and drop hand).
4. Scrollbar button and action follow the mouse outside of the scrollbar. The scrollbar sticks - difficult to make scrollbar stop following the mouse.
5. Example, have two visible windows (for example gedit and the browser) From gedit move to browser by click on browser. ---> result takes forever to recognise the focus and click and go to the broser.
6. Unresponsive UI. In browser highlight text in textarea (with difficulty) then chose Copy (slow UI), from this window click on desktop's Applications (takes many clicks to open), from Accessories click on gedit (slow or takes more than one try), paste (speed of paste OK).
am running Ubuntu 9.10 on my laptop via USB external HDD.Currently it will not boot.I get the logo followed be an immediate filesystem check.At 90% complete it check crashes followed by the following:
init: mountall main process (500) terminated with status 3 Mount of filesystem failed. A maintenance shell will now be stated. CONTROL-D will terminate this shell and re-try. root@c-desktop:~#
i've had alot of problems with karmic koala but i think i should blame it on my computer damn things ancient anyways i want to install puppy linux because karmic requires all of my ram to operate but the only problem is that i can't get my CD-RW drive to burn i've ran an image burn through k3b brasero and gnomebaker and everytime i try to burn the image my computer freezes up i'm ready to pull my hair out i want to get puppy linux on this thing so it'll run faster is it because i'm trying to do too much with not enough RAM if so is there a few extra programs i can suspend untill i have burned the OS or
am i missing some kind of file or program or what i mean i can't even get the disc back out even if it unfreezes i still have to restart the system just to get the disc out i know it can't be my disc drive it's not new but it's never been used till now and it didn't come with a driver disc so it can't be that either all i want to do is get puppy linux installed and move on with my life until i buy a new computer then i'll just install the lastest ubuntu version at the time
i have no problem ( not yet any more ). but i have a question to the development: who had the mangificent idea to change the philosopy of more than 30 year old runlevels ( 0, 1,2,3,4,5,6 ). now when the system is full up who -r and runlevel gives you can anybody imagine how many scripts which are using commands like "who -r", "runlevel" or parse utmp are give up working. i think a couple of thousends. portability is written in unix with capital letters . please send me a message if you plan to change the runlevel to "S" that i can modify my scripts.
I have a Dell Latitude D620 which came with Windows XP. I have just installed Ubuntu 9.10 on the laptop so it can dual boot but I can't connect to the internet.I have a dynamic IP allocated by my broadband service provider which I access by a wired Netgear DM111P router (not cable). It still works fine when booting up windows.I've read through lots of posts by others trying to find a solution as the 9.10 install has just been done and I've not changed anything.
My tentative assessment is the laptop, when running Ubuntu, is not communicating with the router as there seems to be no IP address allocated by the router.
