General :: Making A Data Partition And Installation Of Buntu 10.10
Nov 28, 2010
I wanted to migrate from ubuntu karmic to the latest ubuntu 10.10, but i already have a lots of data on my hard disk in home directory. i was thinking if it is possible to transfer all the data to one directory and make a separate partition of it , so tht when i install a fresh copy of ubuntu 10.10 on my system i need not format this new partition ,which contains al my data.is it possible tht this new partition will automatically get mounted on the new system without the need to execute commands from terminal every time i start my system. if there is any other alternative way for solving this problem i would follow tht too.the reason for my migration is that karmic is really troubling me a lot and so many applications including my sound device have failed to work and i am not able to rectify them..

I'm attempting to add an additional partition through KDE's Partition Manager, but my RAID 0 is not recognized by that program. I'm wondering what partition utility is used during *buntu installation, as this properly recognized my RAID 0, and I was able to successfully manipulate the partitioning scheme.

I purchased a new Desktop PC and MTS MBLAZE data card. It works in Windows XP OS. To make it work in Fedora GNOME OS how can I proceed? Which software do I need? Where do I get it and how to download and instal it in my PC? The firm selling the data card do not have an easy solution.

When using the manual partitioner on the fedora 11 installer on the live cd, both for 64 bit and 32 bit, it will not allow me to create a new partition. I understand that I have four primary partitions and it cannot have more than that, so I tried deleting one of the partitions, then creating the new ext4 partition for F11. It still fails and gives me the same bugsee attachment)
how to read this, especially since there is so much there. I see at the top it says that there are 4 primary partitions, could it possibly still be seeing 4 primary partitions when trying to create the new one, even though I am deleting one of them? Other than this, I truly have no idea what else I can do.
EDIT: Attachment wont load up for some reason, here is some of the error file:
anaconda 11.5.0.59-1.fc11 exception report
Traceback (most recent call first):
File "/usr/lib64/python2.6/site-packages/parted/disk.py", line 183, in addPartition

I've been using Ubuntu 10.10 for just under a week. Recently, a partition called 'Data' has disappeared, and all my music and documents along with it. The folder is not to be seen in Places or on my desktop. My only way of finding it is to go to terminal. But when I try to open it there I get an error saying I don't have permission to read it. In Puppy Linux and SliTaz I can easily find the partition and read it. What should I do to bring it back in Ubuntu?

I have never worked with Linux before but as part of my new job I need to format and install a program on a compact flash card. I have followed our procedure to the T but when i install the card I get a No bootable partition error. Here is what I'm doing. I go into Gnome terminal and change to my directory to "cd dcmsetupdir" (this may not be important but I want to give as much info as I can. Then I type "sudo ./format_cf". once this is complete (no errors detected), I type in "sudo ./install_cf" this seems to install correctly but when I boot up the unit with the card in I get the no bootable partition error.

I have 10 GB drive with win98SE taking 2 GB and 9.04 taking 2.3 GB, then the rest is unallocated space. I am trying to use upgrade manager in 9.04 to upgrade to 9.10 (I have 9.10 CD but it fails to install - tried to download it several times. I know upgrade manager solution works in principle, but upgrading to 9.10 says it needs another 1GB of space.
I have used 9.04 live disc to start GParted but there seems no way to resize the 9.04 partition to use the unallocated space - can only resize it down. Making the unallocated space a partition does not seem to help. How can I go from here to make enough space to upgrade to 9.10 and keep Win 98

I was a regular Windows user and have installed Ubuntu 10.04 LTS 2 days back. Not really sure what was my mistake during installation but that had erased all my data. I lost windows completely and lost all my data in all 4 drives including drives itself.I searched in internet and forums as how could I recover my data, and got solution to use test disk. Testdisk worked perfectly, I recovered my 4 drives and retrieved data for 2 of my drives. But I still cann't retrive my important data from other drives.I guess data still exists in hard disk. (no free space , and no data)I know there could be several threads which had solved this kind of problem.

I want to install Ubuntu (10.10) on the 1TB drive I need to unplug the SSD while installing it in order to dual boot by pressing F8 (the way I want it to be) so that Grub doesn't get installed on the SSD. What I want to know is can I partition the 1TB drive to install Ubuntu without any data corruption or anything? I have read that NTFS can lose data if partitioned with data already on it (I have no way of backing up my 100GB of files on the drive, as currently this IS my backup drive). What I want to do is have 900GB for files, and a 100GB partition (or partitions adding up to 100GB) for Ubuntu- what is the best way to do this? I don't need seperate partitions for ubuntu, can I install the whole thing to the 100GB partition and boot from it? Or do I need swap as well? I was thinking of making 900GB partition, 4GB partition for swap (if needed) and 96GB partition for Ubuntu (/ if I understand) as this is what the "erase entire drive" option creates.

My primary drive is 250GB and has the root, home and var (I'd read it's good to put var on a separate partition for MythTV which I'm planning on doing) on separate partitions. I have a second 1TB drive that I'll be using to backup the 250GB drive and also host less critical data. I've created two partitions on this drive, one 250GB and the other covering the rest of the drive. I'd like to move the Videos directory out of Home on the 250GB onto the 1TB drive but can't find a definitive way of doing this. Should I just follow this guide for moving the home folder to a new partition? Next question is when performing a backup of the 250GB drive how do I make sure it's going to the 250GB partition on the 1TB drive? Can the different partitions be mounted separately?

I have a 10gb partition I use for data. The /home is there, and I mount any other data partitions (like /music stuff) onto /data. These other mounted partitions add up to something like 60gb of diskspace, but since they're just mounted on /data, I believe they only take up 4096 bytes per mount point.
Some time ago, I found that the /data parition was full. There was only 330mb of data in /home, so I was perplexed. I found a cache dir under .opera that reported itself as having 132TB (yes, that is terrabytes) of files. I thought deleting the offending directory was the answer, so I deleted that cache dir and every file or subdirectory in it, but the /data partition is still like 99% full. I am a wee bit confused.
This very full /data partition is my only jfs partition. The other mounted filesystems are either ext3 or ntfs. Is it possible that the journal of this filesystem is corrupted? Or is hidden somewhere on the /data parition, taking up a bunch of space? (I obviously don't know enough about filesystem to know whether or not this is a likely scenario.) Is it possible to zero out (or delete and re-create) the journal, if so? The only other thing I can think of is to move all the /home data off, delete the partition, then re-create it and move /home back. I will do that if need be, but I'd rather learn something from the experience, weird as it is.

During a recent request to install fedora 11, I ran into an interesting problem. It seems that between fedora10 and fedora11, the developers switched from fdisk, to parted for creating the initial pre-mke2fs partition table creation.
It looks like the implementation of this is broken, as it's writing the partition table with overlapping cylinder boundaries. While this can sometimes be ignored, it can in certain cases cause significant data corruption.
On an installation I took it through, using the latest installation media, in both manual & automatic partition creation, the layout looked like this:
The last two partitions turn out fine, for some reason. However, those two partitions should not have overlapping cylinders. After my very first installation, the system was completely unbootable, and not even fsck wouldn't rescue it. If this is possible, then that means that a system that's been online for months or even years could simply drop out of functionality simply due to a byte or two of system-critical data falling on that last cylinder. Considering that a lot of the time kernel data ends up on /dev/sda1 (commonly the /boot partition), this is something that should not be ignored.

I want to install Ubuntu side by side with Windows. I have a big NTFS partition that has a folder with the same name as my username (let's say "joe"). Inside "joe" I have my personal files. Outside "joe" but still in the partition, there is random stuff that doesn't really belong anywhere, or now useless programs that I had to install there because the main Windows partition ran out of space. If during the Ubuntu installer I choose to use that partition as /home and make a user called "joe", will everything work fine?

While attempting to install FC12, Anaconda took it upon itself to overwrite the partition on my backup disk. Now I need to figure out if there's a way to get at least some of my data back. If there's a better place for this question, please let me know and I will happily move it. Using Linux since 1993, other Unixoid systems since 1986. I bought this machine back in 2004 or so. It was a pretty decent machine back then, but it's showing its age now: 370Mb of RAM, 2 hard disks with 80Gb and 120Gb (I don't think the other specs are relevant, but just let me know if I'm wrong). In a fit of insanity, I decided to install Gentoo on it. Don't get me wrong: I love certain things about Gentoo. But the constant fiddling that's required, while it can be fun at first, gets old kinda quick.
So various and sundry things have been going wrong with it here and there (CD-ROM, sound card, etc ad infinitum), and, finally, it wouldn't even load X any more (almost certainly some final Gentoo update which broke something) and I said "screw it, I'll just put Fedora on it." This is what I use at work, and plus I have a good friend who has far more patience with admin stuff than I do and Fedora is what he knows. So, last night, I pick up an FC12 CD that I have lying around and decide to finally just reinstall the whole thing. I went so far as to buy myself a Passport USB drive, 319Gb, and have been backing up up all my stuff very regularly to that drive. I go through one final cycle of backing up and verifying before I start the reinstall.
So my drive is solid, and contains everything I could possibly need (and probably quite a bit of stuff I don't). After booting into FC12, I used Palimpsest to explore the partitions on the existing hard disks. Not sure which was which, I mounted the Passport, where I have cleverly saved a copy of my fstab. Using this, I can see which of my partitions were /boot, /, /home, etc. Most of my personal data has been put into separate partitions so that I could reinstall without blowing away the data. I hope that I can do that there, but, if I can't, no matter: I have a backup. I find some bits of empty space and delete a few of the partitions and recreate them, consolidating the empty space. Still confident in my backup, of course.
So I run Anaconda. Nothing happens. Eventually, I figure out that it won't run the graphical interface because I don't have enough memory. I can use the text version, no biggie. It gets to the part about the disks. I tell it which hard disk to install itself onto. For some reason I think it's going to pop up and ask me about the existing partitions and whether I want to keep them or rewrite them (maybe that's a previous version of Anaconda? or a different installer altogether, who can remember). It does not. It babbles something at me about LVM (which I've personally never really used before), and then promptly locks up. Obviously standard Fedora on a low-RAM machine like this is doomed to failure.
I poke around on the Internet, and I eventually stumble on the Fedora "spins" and select FC13/LXDE. Hopefully this will have better luck. Reboot with the new CD, take a look at my hard disks. It has completely overwritten the old partitions, replacing them with LVM partitions. But not a big deal: I have a backup. Take a look at the Passport. Its ext2 filesys has also been replaced with an LVM partition. Proceed to beat head against wall. So, obviously what happened is, since I (foolishly) had the backup drive mounted at the time I ran Anaconda, it assumed I wanted it to take over that drive as well, and just formatted everything it could lay hands on as LVM. It certainly never asked me my opinion on the matter.
But, fine, I shouldn't have had it mounted. The question is, what do I do now? My first, panicked instinct, was to just set the partition type back to 83 (I believe LVM is 8E), which I did (using cfdisk). That might have made it worse; I dunno. But I'm pretty sure I haven't written anything else to the disk since then. I've tried testdisk (nothing useful; although it can seemingly find the underlying deleted partition, it won't actually do anything with it), and a bevvy of Windows Linux recovery programs (Stellar Phoenix, DiskInternals, Raise, and R-Linux), all of which were completely useless except for R-Linux, which scanned the disk for eight hours and was still going when I had to interrupt it (I may come back to that one, but so far it doesn't look too promising).
My primary problem is that I can't make an image of the disk because this little Passport is the biggest hard drive in the house. I would certainly feel better if I could image everything off it and then play with the image. But, of course, it doesn't matter that very little of that 319Gb was actually being used: I still need 319Gb worth of space to make an image. I ordered another (larger) Passport, which should be here Wed. Once I have that I believe I can do something like so:
Code:
dd ifs=/dev/sdX ofs=/mnt/bigpassport/smallpassport.img bs=512
Right? Then I can muck about with that image in some amount of safety.
Of course, I also have the original hard drives, which are not so large. testdisk can identify the original partitions on those too, but, again, won't actually do anything with them. If I could find something that would image just the partitions I care about, I could probably save those as well, but I don't have any other external hard drives with 120Gb of space free. Can I somehow take the info that testdisk is giving me about those original partitions and use dd to get only that part of the image? Are there other recovery tools I haven't considered? I have a Windows (Win7) laptop, a Linux laptop (FC10, I think), although its power cord is flaky so it's not too reliable, a smaller Mac, a really old Windows box (XP on it, I think), and this formerly-Linux box, which I can only boot off CD's at this point. There's nothing on this disk worth the 500 bux that professional data recovery would charge me, but it's worth a day or two of my life to try to get at least some of it back.

A HP Netserver LP2000r, with original SCSI controller and HP NetRaid-2M controller, 3x 36GB Ultra3 HDD in RAID5, Debian (sarge/etch), has crashed after 992 days without reboot. From all that I can see, a hardware failure, most likely with the memory. The HP Diagnostic tools cannot find any problem, but everytime I boot into Knoppix, I get between 2minutes and 2 hours of runtime, and then either a kernel oops or just a complete and sudden halt.
Well, the box has earned its money. However, there is some data on the drives that I need to recover (yes, I have beaten myself up properly about not backing up that data, don't even go there !). There are three partitions: sda1 is /, sda2 is swap and sda3 is a LVM volume with 3 logical volumes on it. As far as I can tell, the hardware defect must have been creeping in and has made a total mess of the inodes in all these partitions.
After booting into Knoppix, I can restore the volumes using pvscan, vgscan, lvscan, vgcfgrestore and vgchange. If I try and mount them: mayhem. So I try and check them, using fsck.ext3. All sorts of interesting nonsense, such as a completely empty inode 11 (the first inode) and then obviously from there on all else is pointless. I tried using debugfs, but the information on what to do with it is somewhat spurious.
P.S.: Tomorrow I will go and get myself a 16GB Flash Drive and then hopefully I will be able to dump the partitions one by one onto that drive and transfer the images onto a different computer for analysis and data recovery.

I have just spent dome time using gparted to sort out my partitions. I have a vista partition, a fedora one and a big chunk of unallocated space I wish to use as my data drive.
I want to move my ~ folder to the new partition and have windows/vista access the folder and write to the Documents, Downloads folders etc.
What is the best format to use?
Also I plan to start backing up my partitions to a server, for instance using g4l to save a linux image (maby a windose one too). Is there any benifit in keeping all the hidden files (ones starting with period '.') i.e moving the whole ~ folder or would I be best off leaving the ~ dir and moving the folders I know i use such as ~/Downloads, ~/Documents etc?
And how should i preform the move of all these files? 'mv'? do i need to add any special options?

On my laptop (Dell Studio 1745) w/500GB HD, I have a common data partition shared by openSUSE. Fedora, FreeBSD, and windoze 7 currently. I would like to encrypt this partition (/Common) and have it accessible from all distros either with a passphrase key in /root or on a flash key. I've been researching on the web and there seem to be several possibilities using eCryptfs, Luks, cryptosetup, or any of several methods.
My question is, what have people here used and how well did it work? Also, what was required for setup (I'll probably have to explain/teach it to my wife who is technology challenged-but I still love her anyway) and my daughter who's just getting into linux. I would like to be able to keep the entire directory on the hard drive but also have the ability to copy it to external USB device for transport.

I am installing a custom 8.04 live disk (basically, a mirror of my whole system with user data intact, sans all non-OS files) from a USB key with remastersys for the .iso creation, and UNetbootin for the bootable USB on a brand new 120GB PATA WD HDD. Both do nicely so far, so I have a working livedisk to use until I need to install Ubuntu to the drive.
I had a pure linux box, but I need to add XP with dual booting now- I have to use Autodesk Inventor 2010 software for my college class on my laptop, so I don't drive 30 miles to use the 1 computer lab equipped with that software. I'm not new to Linux, but I am new to more in-depth partitioning. I've taken the lead and looked into things- read this good guide, among others:
HTML Code:
http://www.psychocats.net/ubuntu/partitioning and noticed that there is a way to more deftly use partitions so that personal files can be shared access and write between Windows and Linux partitions- with this:
HTML Code:
http://www.fs-driver.org/ Ubuntu is still my main OS, but being able to access all my media/data files between the 2 systems would be nice. Problem is, until now, I've put everything on a single partition because I didn't know better. Now I do, but am a bit confused with all the guides as to what's most efficient, especially in my case where full RAM speed is crucial to running a single program.
Here's what I know I need to do: 1. The Windows XP install I know needs from 20-30GB for Inventor 2010 LT to work well. I don't need anything else in XP spacewise- it's just being added for Inventor. 2. I'd like to create a separate /home partition for Ubuntu this time to save my user data, making future upgrades much more painless (I will be getting Lucid soon). How that works when upgrading, though, I don't know yet..
3. I'd like both OSes to share all my personal files (docs, pics, music, Inventor design files) if it is an efficient choice that works without problems.
4. Finally, because 2GB is minimum for Inventor to run decently, I need to maximize the speed of my RAM for it- from my reading, these so-called "swap" partitions can somehow be added for buffering this- people seem to sugguest the swap be half the size of the RAM for fastest speed, and some say add separate /usr or other partitions. I'm not clear on what would be most efficient for me.
I have limited HDD space- because of my laptop's BIOS, this single 120GB drive is the biggest I can get on my laptop, so efficient partitioning would make a huge difference for me. Before this, a 60GB HDD was in this. I'd like to see some added space for my data storage, but still keep things as fast as possible for Inventor when I use it, and Ubuntu.

I'd like the final layout to have a Windows partition (will start out as XP and will become Win7 when I can afford yet another copy), a partition for Ubuntu, and a shared Data partition that I can use for all my files between both OSs. I think this should be fairly straight forward with Linux on a Primary partition with / and swap. Only thing is, from what I've read (and yes I know this is a bit old school) it might be a good idea to put in a /Home partition so that I can reinstall new upgrades and maintain settings. But I don't want to max out my 4 primary partitions so I can use a 4th partition as a kind of sandbox for OS testing without using VirtualBox all the time.
This leaves me in need of some advice, I've never used Fdisk and I was planning on just using the Ubuntu installer to do all of this, but I don't know if I can create /Home as a logical partition in the main Ubuntu partition and still have the benefit of being able to reformat /root without losing /Home. I might have just confused myself, because no matter how many guides and How Tos I read I still don't really get extended partitions, I understand logical vs. primary but extended is...confusing. I need the Ubuntu partition to be bootable, so it needs to be a primary partition...I think. Unless I can have: /boot, /, swap, and /Home...
Also, if Ubuntu can read NTFS, and Win7 can read Ext3, what should a do with /Data? Or should I just go with FAT32 and be done with it. (It's a big HDD btw, 640 GB, so /Data will be fairly large)

I've got an external hard drive with one large data partition on it. I also have four computers to connect it to (individually, not at the same time). Three machines are running Slackware and one is running Ubuntu 9.10. I need to be able to just plug the drive into whichever machine, mount it (preferably to the same location each time) and not have to worry about user permissions and such. Do I just chmod 777 all the files and folders or is there a better method for different 'users' to access the same partition? And how about mounting to the same location each time?
Now the second part of my question I'm pretty sure I'm not able to do but just in case..... is there any way to encrypt the information safely and make it compatible with a Windows XP machine?

following problem. A friend phoned me in despair. Her Ubuntu didn't start any more - ASUS-Laptop switched on stops at a ramfs-prompt.
I started Puppy-Linux from DVD-Drive. Worked fine. But puppy can't mount her /dev/sda1 partition either. At least you can see that the partition is still there. Fsck stops with an error. May be the initial problem is a sort of bad hardware by which bad bytes were written to the hard drive. Hard drive and/or memory could be replaced but not the data.

I used a Kingston 8Gb flash drive as a live usb recently (copied the live iso image over using dd). I am done with the installations and all but seem to have a problem. i cannot format my flash drive. It now shows as a live CD (800 or so mb). Is there a way to fix the partition table back? I guess if i copy a partition table image from some other 8 gb drive that might fix the problem but i dont have any other flash drives. Is there a solution possible or am i stuck with a live usb forever
