Ubuntu Installation :: Moving From OpenSUSE With Raid
Apr 9, 2010
I have run Ubuntu in the past and then switched to OpenSUSE several months ago and set up raid 0 on a 500gb hard drive and 700gb hard drive (I went with openSUSE because of the graphical raid setup.)
My whole partition setup looks like this:
500gb Hard Drive:
750gb Hard Drive:
md0 is the two 400gb partitions on each drive for a total of 800gb space on my /home partition ext4 filesystem ( 380gb space used ) md1 is 100gb ext4 / partition.
all raid 0
Now I was wondering if I downloaded the alternate install cd for ubuntu ( as OpenSUSE has crashed for the second time because of bad updates ( starts, but gets to terminal only ) ) would I be able to keep my raid 0 home partition and wipe the rest of the each drive and setting up Ubuntu keeping all of my files and settings intact, just to install my programs I need all while keeping my old settings ( such as firefox bookmarks, virtual box utilities etc. ) intact.
From what I know it's possible, but I don't know much about the Ubuntu Alternate install disk ( as I have been dealing with dependancy hell on OpenSUSE ) but in OpenSUSE it wont let me keep the old raid setup ( md0 ) Im guessing it is possible to set up the home directory on a different hard drive and then going back into the live cd, editing the fstab, and switching it to md0, if this is even possible, or would I need to configure the driver on that system before I did that Oh and I forgot to mention that I've only been running 64bit operating systems.

I have a Linux installation that currently uses a 40GB hard disk. It is partitioned as follows:
Code:
The disk has recently started to make a lot of noise, so I'd like to replace it before I lose data.
I have a pair of identical 160GB blank hard disks that I would like to use as a software raid1 array (The existing 30-odd GB root partition would be resized to fill the new disks).
How I could get the data on to the new hardware without losing anything?
I'm having trouble with Ubuntu 10.10 and stable device names. When I installed Ubuntu, the root drive was the only one in the machine; it obviously got /dev/sda.
After the base installation, I installed three additional 2TB drives to make RAID-5 array. Ubuntu renamed the root drive to /dev/sdd. While annoying I lived with it.
After creating a single partition set to "Linux raid autodetect" on each drive, I created the RAID-5 array:
Code:
All was going well until a reboot. When rebooting Ubuntu decided to make the root drive /dev/sda this time and now mdadm --detail /dev/md0 reports:
Code:
How to fix the array and make the device names stable?
A while back I successfully set up a software raid (mdadm) install of ubuntu server on a cheap Compaq machine. I'm pretty sure it's running an nForce 430 chipset. Anyway, I put 3 2TB drives in it and set up two arrays: a small raid1 array for /boot and a raid5 array occupying the rest of the drives.
One point of note here is that the raid1 array never seemed to "take hold": the partition is empty, and the system has been booting entirely from the raid5 array. I'm not sure if this is relevant or not: just throwing it in there in case it is.
Anyway, I recently upgraded my desktop PC, and planned to hand down the Q6600 and DG33TL motherboard from it to the server. I did the hardware upgrade, but now the system will not boot. My question is: why.
Boot fails with the following error message:
"No bootable device -- insert boot disk and press any key"
This to me suggests that it's not even getting to the point of running grub2: the mobo itself just isn't finding anything it considers to be bootable.
I've tried all combinations I can think of of configuring the SATA support in the BIOS (modes include IDE, ACHI and RAID, all in combination with UEFI boot enabled and disabled). The system does detect the three drives: it lists them in the BIOS config screen.
I've booted from an ubuntu rescue USB drive and I'm able to see the drives and even assemble the array. I can mount the LVM partitions therein and do what I'd normally be able to do with them.
Everything *seems* fine: it just can't boot.
Grub2 is something of a mystery to me, so I'm not exactly sure what I need to do to get it booting again, if indeed it is a problem with grub.
I had Ubuntu 10.04 on a machine with SilImage and 3Ware raid controllers (Fakeraid) working in it just fine. Built a new machine with 10.04 as well then moved the whole array across (Cable for cable etc. - NO changes). The new machine 'sees' the controller and 2 drives per card in Disk Utility - all looks good, BUT the array does not seem to work as an array. Obviously the drives are full.
If you want a full run down as to WHY I want to do this, read here: webhostingtalk.com/showthread.php?t=899909Basically, my ISP could not get my server running stable on a simple raid 1 (or raid 5) so what it came down to was having them install my system on a single disk. I don't exactly like this, main reason being, if the system (or HDD) crashes, I'll end up with another several hours of down time..

I have a Windows 7 installation with a boot partition on the RAID. I also want to have a dual boot with openSUSE 11.2 but I don't know how to set correctly my partitions. I have some unallocated space next to the Windows C: partition. When I try to install openSUSE it makes a suggestion to create some partitions that i don't need and don't want, and even doesn't mount them. It also creates a / 80GB, /boot 36MB, swap 2GB and /home 20GB partitions, so I am in lack of free space.
I don't know how to create screenshots during installation. Maybe I'll try to reinstall later and pick some screens in english, because my system language is bulgarian.
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'll have a Sony VAIO AR290 with 2 HDD, earlier I'll have a Windows XP and SUSE and RAID was turned off. Now I turn on RAID in STRIPE mode for better productivity, Windows 7 installation was successful, It creates MBR partition (100 M and C: HDD. During SUSE installation(I've chose all parameters- swap and partition) installation process stop at 1% on "operating with HDD" and my VAIO dont answer on any key pressed (alt ctr del, ctr c, esc) and I'll should to turn it power off. During surfing web, I'll find some solutions to solve it by creating root partition but It hasn't any results.
I'm trying to get my Adaptec RAID 6405 working on fresh Opensuse 11.4.I need to make a driver/module for this because aacraid module doesn't see the raid controller.
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]
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.
It's been a real battle, but I am getting close.I won't go into all the details of the fight that I have had, but I've almost made it to the finish line. Here is the set up. ASUS Z8PE-D18 mother board 2 CPU, 8 Gig Ram. I recently added an OCZ Agility SSD, defined a raid 1 virtual disk on the 1 terabyte WD HDD drives, which will holds all of my user data, the SSD is for executables.The bios is set to AHCI. Windows 7 installed fine, recognizes the raid VD just fine.
I installed Ubuntu 10.04 by first booting into try and mode, then opening a terminal and issuing a "sudo dmraid -ay" command. Then performing the install. I told it to install the raid components, and told it to let me specify the partitions manually. When setting up the partitions, I told it to use the free space I set aside on the SSD from the Windows 7 install as ext4 and to mount root there. Ubuntu installed just fine, grub2 comes up just fine, and Windows 7 boots with out a hitch, recognizing the mirrored partition as I indicated previously. When I tell grub to boot linux however, it pauses and I get the "no block devices found" message. It will then boot, but it does not recognize the raid array. After Ubuntu starts up I can run "dmraid -ay" and it recognizes the raid array, but shows the two component disks of the raid array as well. It will not allow the component disks to be mounted, but they show up which is annoying. (I can live with that if I have to)
I have fixed a similar problem before by setting up a dmraid script in /etc/initramfs-tools/scripts/local-top ... following the instructions found at the bottom of this blog:[URL].. To recap: My problem is that after grub2 fires up Ubuntu 10.04.1 LTS (Lucid Lynx), it pauses, and I get "no block devices found" It then boots but does not recognize the raid array untill I manually run "dmraid -ay". I've hunted around for what to do but I have not found anything. It may be some timing issue or something, but I am so tired of beating my head against this wall.
I like the buttons on the left. I'm running 10.04 & I know how to move them. The problem is that changing themes will move them back right. OK, if the new theme has them on the right that's OK. But going back to the other theme doesn't change them back. They don't seem to be controlled by the theme, or I'm just not doing it right.
I have installed fedora 11, now i want to install touch driver for my dell 15 laptop. when i m moving cursur its moving but when i m clcking on touch pad to open anything its not opening, to open i have 2 select any file then i have to click touchpad keys.
Recently I was working on something on my windows partition (on the same HD as opensuse), and all the sudden windows stopped working and I got some bad sectors on my HD.
Now, my opensuse installation is on the same HD as windows, but I need to get rid of that HD soon because it's starting to get worse (and I think opensuse is randomly crashing because of it).
Is there any way to transfer my opensuse parititon/os to another hard drive?
I have a wireless-G adapter that I use currently with openSuSE; the router also supports wireless-N, and I would like to move to an adapter that matches the router. The current adapter is USB (despite this being a desktop) and uses WPA2 (which I would rather keep). What is the best wireless-N adapter that matches the feature set?
I installed openSUSE 11.2 on an external HDD to test. I think it's brilliant, and want to move it to an internal HDD. What is the best way to do this? I don't want to lose all the programs / tweaks I've made to SUSE so far.
Coming from the Windows' world, it's as easy as taking an image of a partition and restoring it over a new HDD partition.
I am going to move my ubuntu to a different drive. Right now I have it on my primary sata drive in an extended partition. I want to move the whole installation to a different drive. Is there any way to do this without reinstalling ubuntu. Grub is installed onto my 100mb windows 7 boot partition. Is there a way to make grub point to the moved ubuntu installation on the different drive?
today I obtained a computer from a friend who had just bought a new computer, and they were getting rid of the old one. Being a linux user I couldn't let a perfectly good albeit slow Windows XP computer go to waste. With Ubuntu 10.04 install it is lightning fast. I've noticed it is faster than the current computer I use as a server, and want to migrate the HDD over to the new machine. I know there are issues when doing so with Windows as it registers the hardware and has major heartburn with this, so I was wondering if Ubuntu or linux in general will have any problems. I simply want to move it over.
I don't have a problem with reformatting as it has it's own /home partition, but for obvious reasons I would like to minimize down time. I did a search on google and on the forums here and I didn't find what I want to do.
I work with ubuntu 10.10 64 bit on a hp pavilion 2713ca laptop. Everything is fine presently, except for the fact that I will be soon out of space on the actual sda6 partition (only 2 gig left).
I would like to move the ubuntu partition with all its content to a second one where there is a lot of space, that is sda2. So my question would be twofold.
1) What software can I use to do that (gparted, clonezilla, ... ) and is someone is familiar with the procedure?
2) Will there be an easy way to change the grub.cfg file? (for example, will the command grub update be enough to boot to new setup)
I run a dual boot machine with XP pro and Ubuntu 10.10.I want to change the 10.10 to the netbook remix version. How do I install remix instead of 10.10 without damaging XP?
I'm trying to copy files from my external hard drive to the desktop and instead of the usual copy or move to options, I get a widget menu! How do I correct this so I can copy files?I'm running opensuse 11.3 KDE 64bit
I have an 80 GB XFS / partition which is dying. Got some errors like this: ata9: SError: { UnrecovData Dispar BadCRC Handshk }
It's not a problem to create another partition, I've got 2 500GB and 2 1TB disks, all EXT3. I've also 2 80 GB disks, 1 for / and 1 for /home. I will remove the 2 80 GB disks but I have a lot of stuff compiled myself. I use openSUSE 11.1. Is it possible to create a 80 GB EXT3 partition on each of the 500 GB hdd, 1 for / and 1 for /home and move the data to it? must it be done with the DD command or can I easily copy everything within a live-cd. The /boot and swap are already on one of the 500GB disks, and there is no bootrecord on the 80 GB disks.
I'm a plain user of Open SUSE 10.2 for more than six months now on a dual boot machine (Vista Ultimate) and I'm 80% mostly on Linux now but because of my job I still have to keep windows.
My 1TB HDD is full and I've got a new 1TB HDD to add to my system. My plan is to leave this HDD only for Vista and to use the new HDD for Open Suse, changing it to the 10.3 version and without to lose my data and my settings (keeping the Home directory).
Considering that I am a ignorant could someone give me a step by step plan as much as detailed possible, in order to succeed?
I have a dual boot system with Vista and OpenSUSE 11.3 . Linux is distributed over 2 partitions: one for /home and one root partition for all the rest. As this root partition is getting filled, I thought of taking a 10 GB partition from the Vista partition and using this for the /usr folder (= 6 GB). This partition is a primary partition, while the rest of Linux is on secondary partitions.To be save, I renamed the existing /usr to /usr-old and created an empty /usr as mount point. I changed fstab to load the root partition, the /usr partition and then the /home partition.But when I started the system, there were a lot of errors about files not found in the /usr folder, lthought this folder and is content were clearly present when browsing the filesystem. What went wrong? Hard links? Other system configurations to change? Not possible to put /usr on a separate partition?
Currently, his mail is coming in on 2 addresses. He'd like to take the mails from one source and add it to the other.
The idea is to fetch the mails from the least used address - on the provider's POP server - and forward it to the other address. He can use the SMTP server from the same provider to send off the forwarded mails.
This operation would be cron'ed to run every few minutes.
I have an opensuse server which handles 5-8 sites, a mail server and a nameserver.I will move it to a new location and I'll have a different IP. Now, I didn't configure the server myself, so I don't know what to do so that the mail server, the sites and the nameserver to work in the new location with a new IP.
Does it suffice to change the IP of the nameserver from my domain registrar? What any other modification I'll have to do in order for the mail and sites to work at the new location?I searched tutorials on moving a server to a new location but I didn't find any...
I have a IBM T42 (using it now to write this) and a newer Lenovo T500 (with a fresh install of Ubuntu 9.10 on it). I want to take all of my programs and config of those programs, plus all my /home directory information/files/hidden files all over onto the new machine. There may be other stuff I need to take over to, and don't know enough about to comment here.
But basically I want my new system to look and work like my old system, with all the same programs and user data, all configured in the same way. Is there a way to do this over the network or another way? I can't even get the two systems to see each other over the network, even though Folder Sharing is enabled and (I think) all the right components are installed. I even checked to see if my user had permission to share files on both machines, and I do.
Currently I am running Ubuntu 9.10 on an older P4 system with EIDE harddrives. My primary HD has a WinXP installation and GRUB. Ubuntu is installed on the secondary HD.
I am happy enough running Ubuntu that I would like to remove my WinXP disk, move the disk with Ubuntu on it to be the primary boot drive, and then install a new drive as the secondary.
However when I tried to simply move the drive with Ubuntu on it from the secondary to the primary EIDE position the system would not boot. I assume that this is because there is no boot loader currently on that drive.
how do I put GRUB on the Ubuntu drive so that it can become the boot drive? Or is there some other way to accomplish what I am after without having to reinstall Ubuntu?
I've been setting up a media server on a an actual server machine I picked up dirt cheap, and had it running xUbuntu fine. gave it a 5gig root directory, 5gig swap partiton, and three 34gig storage drives. Everything was running smoothly.
Just recently I learned that the 5gig's dedicated to running my operating system of choice, aren't enough to install all the software I wanted(I might be just a little greedy). The first logical step to correcting this problem was to move /etc to one of the storage drives and create a link were it was, but not being entirely sure how xUbuntu would take that, I thought I'd get an expert opinion.
The thread prefix is "all variants" because I have installed the desktops for kUbuntu and just plain Ubuntu on this machine(what I meant by being a little greedy).
