Ubuntu :: SoftwareRAID Still Work After Fresh Install?
Aug 16, 2010
So apparently RAID configurations on desktops are pretty much worthless using the motherboard�s internal hardware and BIOS settings. How reliable is the Ubuntu SoftwareRAID? I have 3 HDD�s one that I install Ubuntu on and the other two are in a RAID 1 setup strictly for data backup. Will SoftwareRAID be able to pick up where it left off if for some reason I need to do a fresh install of Ubuntu or will I risk losing the data on the RAID 1 drives? I wasn�t sure about this since SoftwareRAID is obviously software driven and not hardware driven.

I trying to dual boot Ubuntu/Windows 7 on my computer. Here is my problem:
Info:
I used Wubi and ubuntu-11.04-desktop-amd64.iso.
Main OS: Windows 7 Pro 64bit
Videocard: Nvidia GT 240
Problems (underlined) as they occured:
1) Installed Ubuntu within Windows, rebooted, saw Ubuntu loading screen (with dots) and then I get graphics corruption (it's really bad I can't recognize anything in the screen).
Then I booted in recovery/failsafe graphic mode and I let the installation finish, then automatically rebooted.
2) Let it boot without pressing anything and instead of graphic corruption it boots in terminal.
Tried startx command but it says something relative to "x not found". Then I found out I had to install proprietary Nvidia drivers so I:
3) Booted again in failsafe graphic mode (in recovery mode) and tried to install it but... no internet connection.
I tried "sudo ifconfig eth0 up" and I got: eth0: ERROR while getting interface flags: No such device
NOTE: If I let it boot itself (terminal) I HAVE internet connection (found out with wget and ping commands).

I have a VIA Epia M 5000 system with 2 western digital 1TB NAS SATA drives connected through SATA<->IDE adapter. Everything installs and writes as expected except... grub. It never boots, after a message 'Grub loading' I always get 'error: no such disk'. I've tried numerous times and has been attemping to fix the issue for the past 2 days.
/dev/sda
0.999TB 0xfd linux raid autodetect partition
1GB 0xfd linux raid autodetect, logical partition
/dev/sdb exactly the same
0.999TB 0xfd linux raid autodetect partition
1GB 0xfd linux raid autodetect
/dev/md0
RAID1 of /dev/sda1 and /dev/sdb1
marked as ext4, boot point /
/dev/md1
RAID1 of /dev/sda5 and /dev/sdb5
marked as swap
update-grub2 in rescue mode generates grub.cfg with SET root=/mduuid/UUID_OF_SDA1
then after that there's search --no-floppy etc --set root=/mduuid/UUID_OF_MD0
I'm writing this from memory but simply the two uuids are different. Is this correct? I get those UUIDs to compare from blkid. All partitions are marked as bootable. grub-install /dev/sda and grub-install /dev/sdb produces no errors. grub-install /dev/md0 does not work, complains about superblocks or something similar.
Grub.cfg file contains insmod raid mdraid1x and similar lines, so that should be ok. Grub drops to rescue mode with message error: no such disk. Not device, but disk. Google finds many results for 'no such device' error, but I am not getting that error. 'ls' produces
(hd0) (hd0,msdos1) (hd1) (hd1,msdos1) ls ANY_VALID_PATH produces empty newline being printed, nothing more.
setting prefixes manually does not work, with error message 'error: file not found'. ls (hd0,msdos1)/boot/grub also produces empty line being printed. Rescue CD and auto-assemble of md0 and md1 works, the files are there, everything okay, except grub.

I just installed Fedora 13 on a new computer and the timed login for gnome does not work unless you manually select it. This surprised me as I upgraded a separate computer to Fedora 13 and the timed login feature still correctly functions and does not require user interaction.
Code:
[daemon]
TimedLoginEnable=true
TimedLogin=<username>
TimedLoginDelay=3
Adding the above to /etc/gdm/custom.conf only adds an Automatic Login option that you have to manually select and then the computer will login. I would deem this less than useful.
Code:
[daemon]
AutomaticLoginEnable=true
AutomaticLogin=<username>
I know you can substitute the timed login with the automatic login and it will instantly login, but this provides no option to select another user. I have been unable to find any information why this feature no longer works and wanted to know if there is a new way or if anyone knows why the timed login feature was crippled.

It stores all my important stuff, as well as some music and movies.I use a second linux box in my living room to "stream" content via NFS or SAMBA share.The streaming tends to stop several times during playback, and needs to fill up its buffer again before continuing to play.I also have some Windows XP and 7 based computers that connect to this file server.I have noticed that directory listing is VERY slow, and there is a huge lag when I want to save/read a file from/to my home directory.
This is my setup:Ubuntu Server 10.10 64 bit (I have the same problem with 32bit ubuntu)
3 RAID5 arrays with 4 hard drives eachLVM on top of the 3 raid5 arrays.The Logical Volume i use is about 6.5TB, and I use the ReiserFS file systemThis LVM has grown over the years, and has had som replaced disks. So I have used the pvmove, and extend commands a bit.I have tried using IOTop and top to check if there is not enough resources available, but that doens't seem to be the problem.I haven't been able to find out why streaming over the network stops, but I know it is the server that causes the problem.Does ReiserFS have any performance problems with large logical volumes? Would changing to EXT4 or some other FS give any performance gain?

I just reinstalled my OpenSuse 11.3 with the GNOME desktop. As soon as I was done installing and I was on a fresh desktop, I installed the Yast updates that were available, rebooted, and now I can't login to any of my User accounts. Whenever I try to login, it tells me that it is "Unable to Open Session".o any of you know how I can fix this without having to reinstall all over again

I ordered a SuSE 11.4 installation DVD from an online Linux Distro distributer that I've used before with no problems. I did this rather than burn my own DVD from the website. I thought that I might perform a fresh install of SuSE 11.4 on this Dell 1420 Laptop that is currently running Ubuntu 11.04.
Note, this is a completely fresh install, not a side-by-side installation with Ubuntu; I followed the installation sequence that completely repartitions the entire disk for SuSE, and accepted all of the suggested options regarding logon, etc.
Everything goes well ... sort of. The first install didn't reboot correctly, i.e., the set-up that is supposed to run after the initial install never happened and I had to manually power-down the machine and restart from the "safe mode." Needless to say, that didn't work as expected. So, I re-install, from scratch, trying different options: for instance, instead of LVM, I decide to have an un-encrypted partition scheme and accept the "obvious" options ... thinking that the LVM options interacted badly with the install. Eventually I get the installation to proceed correctly, or so it appears: it goes though the entire sequence, including the re-boot, building the default image, etc.
I test this image by removing the DVD, power-cycling the machine, and all looks good, so I begin the process of installing software updates, etc. Being paranoid, I re-boot the machine, and all restarts correctly, etc.
Now here's the annoying thing. The next day, I power the machine on, and it locks at the splash screen. By the way, these are the exact symptoms that I experienced with the bogus/incomplete installations. The boot sequence proceeds up to the splash screen and waits forever.
So, in sum: I spent inordinate amounts of time attempting to install this software, carefully following the instructions provided by the installer. In every instance, after leaving the machine off for a day or so and rebooting, I am met with a splash screen that sits forever. Needless to say, I am extremely reluctant to repeat another day of software installation to only have to re-start with no assurances of success. Either I go back to ugly Ubuntu (which has always worked out of the box, by the way), or I look at other options. I was hoping to use SuSE, but I really don't care which distro is on that machine as long as it works and it provides TeX, R, Emacs, Scheme, and a few other software packages that I'm sure are of no interest to your customer base.

I am looking to update from 11.1 to 11.3. My question is would it be better to update my current setup, or do a fresh install of 11.3? I was never able to get 11.2 to install no matter what I tried so I gave up on it and went back to my tried and true 11.1. What is the best way for me to get 11.3 on my computer?

I have been trying to install openSUSE 11.4 on a Windows 7 laptop, but the suggested partitioning sucks and I lack the skills to do it manually. I would like to format the laptop drive, give up Windows for good and do a fresh install of openSUSE 11.4. openSUSE wants me to keep Windows boot. But I do not want it!
I have tried for an hour now. Can't format, there is no options for that in the openSUSE 11.4 install. There are expert options, but I really do not know how many partitions does openSUSE require. For some strange reason openSUSE wants to keep my Windows partitions. WHY? And if I delete all of the partitions, it wont automatically recreate the needed partitions for openSUSE, it only displays errors and won't let me continue.
For the love of God, do I have to open the laptop, remove the hard drive, put it in another computer and format there?
Why isn't there an option for removing all partitions, formatting the drive and installing openSUSE?
How to disable the forced Win 7 dual boot openSUSE offers and do a fresh install with only openSUSE 11.4 WITHOUT ANY WINDOWS DUAL BOOT BS.
By the way, since my laptops internal DVD is broken and I will not repair it until my daughter is old enough to handle optical drives, I use USB DVD and it won't give me any boot options but starts installation right away. This is also strange.

I'm running Win XP 64 bit and ubuntu 9.10 as a dual boot. I also have the CD for Ubuntu 10.04. My question is, I want to do a fresh install and would prefer it to install over 9.10. Is this what will happen or will it want to install as a 3 way boot??

I just performed my first (successful?) Ubuntu installation. The installation process seemed to go fine, and I selected "Ubuntu Desktop" when asked which set of packages I wanted to install. I assumed this was a standard choice.
After the installation finished, the system rebooted and brought me to a login prompt.I'll mention at this point that I have SOME prior experience with Linux systems, but I'm by no means an expert, and I'm new to Ubuntu. I logged in and tried startx, only to be informed that it was not installed. Having performed a network install, I have internet access on the machine, so I tried "sudo apt-get install xinit" which seemed to work, but now when I run startx, my window shrinks to a portion of my monitor size, the colours invert (black prompt on a white background) and the system locks up. I'm assuming this is some sort of video driver issue, and could probably explore further, but I figured I'd ask some experts first.

I just installed Ubuntu 10.04.1 LTS i386 on my desktop after not having it on there for while then decided to do a clean install on my laptop, which had 10.04, but I had screwed a few things up on it... (and a fresh install is always nice
Anyway, no big deal, just kinda weird: Whenever I google something that I had just googled before on my desktop (ie, a program or something that I had installed, and wanted to install on my laptop also), the link for the result is purple, as if I had already visited that link. But I know I haven't because this is a completely fresh install, I reformatted and everything. The only thing I can think of is that somehow the history/clicked links got transferred to the live CD from my desktop, as I used the same disc for both installs, but this seems a bit improbable imo.
EDIT: I just realized that I did NOT use the same disc for both installs, I couldn't find the original so I burned the .iso onto another one for my laptop install....

I downloaded the iso from the webpage and used the live cd option. From there I chose install and proceeded to install the OS. Everything went fine and I got a message that the system would need to restart without the live cd. I saw the chameleon with the white growing line under (which seemed to run to it's completion) and then I came to a screen mostly white with three option buttons in the bottom right corner and my mouse with the waiting symbol spinning in the middle of the screen. Basicly the symbols stops spinning after a little while and the system hangs. I have tried starting in fail safe mode and run level 3 with the same result. My laptop is a MSI GX740
Edit: I have tried both ubuntu and mint earlier today and those Live CDs wouldn't even start. Also I am using the CD size Gnome ISO. Maybe some of the content on the dvd iso would provide support for my HW?

I have an old Dell desktop that normally runs XP. It has 512mb of ram and I think its a Pentium processor. From what I understood Linux is a simpler, and more stable and efficient OS so I figured I'd give it a shot. First I tried the Wubi installer and got nothing but error messages after the install and it kept freezing and eventually just wouldn't boot at all. So then I tried the full install from disc. Better at first. I soon discovered all the customizable themes and went a little nuts trying to make one user exactly like W7 and the other exactly like OSX leapord just for fun.
I noticed significant slow downs and after some research I came to find that it was taxing my old graphics card. So I setup a user with no changes, still really slow. Then I deleted and reinstalled and I'm now using the bare bones UI. Its still really, really slow. I get lots of mouse drag and just now it took about 7 seconds for the applications window to drop down and 35 seconds to open the home folder. Also about 10 seconds for right click window to drop down.
I'm trying and I really want to like Ubuntu but as of now I'm finding it unusable for even the most basic of computing. I realize my computer is old but xp still runs like gangbusters. So maybe Ubuntu is designed for more modern hardware and more ram, am I screwed? I was looking forward to playing around really customizing my GUI but more importantly I was planning on putting on my girlfriends laptop with similar specs. Her computer needs a reformat but she doesn't have the XP disc. As it stands her XP is still much more usable even with all the viruses then Linux is as a fresh install on my desktop. I don't want to delete xp and end up with a slower linux.

I'm hoping someone can point me in the right direction. I've tried Google searching and searching this forum, but haven't found something similar to my issue. Yesterday, I installed 10.04 off of the live CD onto my Toshiba Satellite A45-S250 laptop (P4 2.8, 1GB RAM).
The main problem is: -if the computer sits idle for more than about 5 minutes, the display will freeze. Image stays on screen, but the computer appears to be non responsive to all input.
-I thought it was a screen saver at first, but it happens even with the screen saver disabled. -I can still SSH into the machine from my desktop computer. I get a normal prompt, and it seems to be working fine from the shell. This is how I have been restarting or shutting down the machine after a freeze.
Secondary issues (that may help diagnose the problem):Even when this laptop appears to be functioning normally (pre-freeze), I cannot switch to any virtual terminals. Well, I can, but when I get there, something is not right. The text does not display properly. It sort of strobes on and off near the top right hand of the screen. -On shutdown, I get a weird colorful displays of what I can best describe as "static". The closing splash screen may just blink on for a second. Other than that the screen stays black until the machine shuts down.
-I've run versions of Ubuntu going back to Breezy on this machine, mostly without issue, and it has been a full time Ubuntu machine since the release of 8.04. These symptoms all appear to be related to video / display.
