Ubuntu :: DD Image Restores Larger Than Actual Size
Feb 13, 2011
I've been working on getting another OS installed on my computer for one of my classes (OS specific assembly instructions). To get this OS running, I had to start using a GPT rather than a MBR table. I backed up my Ubuntu partition (ext4) using the old-fashioned dd command. I've since been able to get everything working again after a dd restore.
The problem is that my original Ubuntu partition was only about 50GB and the dd image only takes up 40 GB. After I restored the image to the new drive (146BG), gparted is reporting 119GB used and only 26GB free. What can I do to reduce the size of my install to 40GB again?
When looking at the disk in baobab, it says the the filesystem is only 47.2 GB and that only 20.9 GB has been used. This is likely what the old partition's breakdown was. So my new question is: How can I make the filesystem capacity (47.2 GB) equal that of the partition that it is on (146 GB)?
I have a large number of folders that each contain quite a few files of varying sizes (from a few bytes to 400kb or so), mostly smaller ones. I need to get the actual (not the disk usage) size of these folders. Is there any way to do this with a command like 'du'?
I just installed Lubuntu 10.04 on old PC (CPU: 700 Mhz, RAM: 640 MB). My swap partition is only 474 MB. I was told it should be twice my RAM, if that's true then I'm really low on swap space. Can I expand my swap space? I also have Fedora 13 installed, it has a 1.3 GB swap partition, can I have Lubuntu use this partition?
In Ubuntu 11.04, all windows display larger than the available screen size, and I haven't found a way to make them fit within the display area of the monitor. This is a Dell 19" flat screen monitor, and I've tried changing the display; no matter what resolution is selected, the windows all bleed past the screen.
I am trying to figure out the "actual" disk size used by my system. When I run the "df -h" command,I am not taking here into consideration the shared memory of 2Gb as it is a sort of virtual shared memory and is not allocated physically. Is that correct ?
i have some issues running twinview through my laptop and an additional monitor. i currently have the nvidia settings such that the monitor is the primary screen. however, whenever i click full screen in videos or another application, it maximizes in my laptop screen. also - when i maximize videos videos, the screen fills up, but the actual video size doesn't tend to increase (it doesn't stretch to fit). is this an adobe problem? ubuntu 10.04, nvidia driver v195, dell latitude d630 laptop.
I have fedora 13 set up on a HP6715S laptop. Runlevel 3 is a problem, because the capital letters are the size of full stops. Reading a little, I can try a grub vga setting, but I am not keen as my screen is 1200x800 and X cannot set it otherwise, so I doubt grub could. There's KMS for radeon cards, and the kernel can do what it likes. The biggest font supplied with fedora is sun12x22, which doesn't even have a euro sign. I gather I can go to a height of 32. Anyone know of larger consolefonts, or a wheeze to double the size of one of the others, e.g. lat9w-16? setfont-h32 increases height, but not zoom, so it's like a double spaced console.
I am running Fedora 10 and would like to move from my 40gb hard disk to a larger (320gb drive). I would like to take an exact image of the smaller drive and put this on the bigger drive.
I'm trying to restore an image from a 40gb partition(6gb used) to a 100gb partition. I set everything up in gparted and and restored the partition image with clonezilla. In gparted, the partition shows the full 100gb partition with 6gb used, however when I boot windows and open the properties on the C: partition, it shows that it's only 40gb. Is there some setting to restore the partition image and use the full 100gb?
I've been using python's PIL (import Image in py2.5) and the command line utility ImageMagick to add text to images and compose images. I can't figure out how to get the composed image not to crop. That is, suppose I compose A onto B to create C. A is short and wide, while B is tall and narrow. I'd like C to be tall and wide, but instead it has the same dimensions as B.
The width of A is determined by dynamic text. My current solution is to get the width and height of A and B, and then create a maximally sized image, T, onto which I compose B and then A.I'm just wondering if there is some way to streamline this. Can ImageMagick do this for me? These operations take a non-trivial amount of time.
Suppose I have a 80 GB hard disk (sda) with 4GB of contents. Using a dd to copy to a different disk
Code: dd if=/dev/sda of=/dev/sdb copies all the contents (including free space). So sdb also needs to be 80GB.
You will notice that in VMWare or VirtualBox disk images, it is possible to set the disk to use only the amount of space of actual data. So a 80GB virtualbox/vmware image with 4GB of contents will be 4GB.
Is it possible to do that with an actual hard disk (sda) image? I want to create an image of an actual hard disk, copy it to DVD and transport it (in mail) for restoration on another computer (having same hard disk).
I have an Ubuntu server and i've installed drbl-clonezilla to clone and restore pc, I have a 40 gigabyte image to be deployed on other pc's with larger hard drive ex. 160 GB or 240giga, my problem is that when I deploy the image on a larger disk I end up with a disk with a partition of 40 GB and the rest unallocated, how can i restore the the disk and use full disk space, the goal is to automate the process. In clonezilla-drbl there is the possibility to start a "prerun" and "postrun" fonction that could help complete the deployment process.
I have a 64 bit Ubuntu 9.10 workstation with two virtualized guest OSes using KVM/QEMU. Also both 64-bit. One is Fedora 12 the other is beta of Ubuntu 10.04.
The problem is that I would like to use a larger size display that is configured by default.
Both guest OSes have a maximum screen resolution of 1024x768. I would like to increase this to something like 1280x900 or 1440x900. The resolution of the host system is 1920x1080.
This configuration appears to be a result of the installation detecting the resolution being reported by the virtual screen during installation.
The only information I have found on the subject suggests modifying the xorg.conf file in the /etc/X11 directory. Neither guest system has this file.
I tried creating one by hand in the Fedora system and managed to render it completely unusable. Not a big deal as this is recently installed and can be reinstalled easily.
I scanned a document with xsane and saved it as a pdf, the pdf shows up great but there is extra white space at the bottom of the document. how do i get rid of the white space and make the document the actual real legal size?
Ubuntu 10.04, xsane 0.996, Brother MFC 240c scanner.I just finished writing a long dissertation on my problem with this scanning environment (which I will spare you). In a nutshell the resulting image, when printed, is smaller than the original document. In writing my dissertation for this post I determined that the cause of the issue is that xsane believes I am scanning an 8.5 x 14 inch document when I am in fact scanning an 8.5 x 11 letter. So the question is... can I change the size to 8.5 x 11? and if so, how? I have not found anything in the xsane Preferences.
Using Samba I have looked into the file that stores all my web sites, there were a few strange files that get larger and larger all the time. File names are _Za01716 and _Za01820, they are nearly 50mb in size now. I know these are not Log files so what are they and can I delete them?
i m using ubuntu 10.4 version and i want to knw that is their any software or something else so that i can resize my images from 2 mb to in kb as my image folder is of 614 mb and i want to put that folder images in my mobile so how can i reduce the size of that folder
After screwing up an update to Ubuntu 11.04 I decided to do a clean install. I tried downloading the AMD64 DVD image of 11.04 but I have found that some of the files cannot be downloaded and appear to have bad file size. In several mirrors and repositories I found the image size to be only 46.1 MB! (Yes, thats "Mega"-bytes, not Giga-bytes. I ftp'd to the repositories/mirror sites and confirmed this.) Yet in many of the HTTP pages it shows as 4.0 GB.I can't believe that the true size is 46.1 MB as the i386 DVD image is over 3 GB. 4.0 GB sound right, but doesn't match the actual file size. So, how long until it gets updated?
I need a command that will check the size (visual size, not file size) of every image in a folder and its sub folders, and make a copy (or even better, a hard link) of that file in a second directory if the image is larger than 1920x1080 pixels (in both dimensions, not just total area). Also, lots of these file names have spaces, so the command needs to be space-tolerant
I'm guessing I would need to use one of the imagemagick commands and find, but I'm not sure where to start. I'm still reading man pages, but I thought someone here might save me some time.
i have to upload a signature image(in jpeg format) to fill a recruitment form which says file-size must be of between 10-20 kb......i have scanned image which is of 9.5 kb.....tried to edit in shotwell photo manager....tried some random things in Adjust and crop menu but my little changes didn't work, it always shortened the file size......as i don't know anything about Image editing can someone tell me how can i increase the file size (>=10kb) i also tried gnome-screenshot to take the screenshot of the image, but it also saved the new image smaller than 10kb....
I created a VM disk image with kvm-img, but I forget what was the max size of that disk image when I created it. Currently, its size is 6.2G, I want to install some large packages in that VM, so I want to make sure the disk image can expand to an adequate size.
When I first installed K3b it burned the first track with no GUI user configurations.The second time it says that the file name is too long and asks if you want to catenate (shorten) it even if it is the same file you have already burned that didn't ask for this shortening of the file name before. Than it gives you an error of "Could not determine size of resulting image file". So my question is how do you use K3b I guess. Brasero won't do multi-session as far I can deduct. It will ask if you want to do it but after ask if you want to erase the disc.If you force it there is no entry of the previous burns.If I could get Brasero to muli-session it would sovle my problem as well. Here's the debugging stuff. I'm using this on Gnome.

Lately, my ISP has started making all Google sites inaccessible for a short time every afternoon (last 3-4 days now). I suspect some kind of DNS poisoning... access always comes back later in the afternoon.
When access does come back, non-Linux machines can connect basically right away, but my Ubuntu machine (the primary one I use) seems to need a reboot, as if wrong DNS information gets stuck in the session and the reboot clears it so that the machine can get the correct IP address.
I have not installed nscd, and IIUC the OS should not be persisting DNS cache information without that package. Every reference I can find online to clearing the DNS cache seems to depend on this package.
The objective is just to get back in touch with my Gmail without having to reboot (since e.g. OSX doesn't require a reboot for the same). What should I do?
