View 1 RepliesI have installed 1tb hard drive and would like to partition as follows:
1) / - 20g
2) /swap - 6G
3) /photos /150g
4) /videos /500g
5) /audio /300g
After 2-3 partition an extended partition automatically created in which I am not able to create specified capacity i.e., say I want 150g of /photos partition, the /videos partition is automatically reduced and a free space at the end appears. Some free space is always there which i am not able to understand. Nevertheless i clicked to create, but I get an error viz. 'device not created'.
I am developing for a Linux based device for which the HOT PLUG option is deactivated. As part of optimizing the code, we also don't want to create device files for unused devices. We understand that both USB attached and fixec SCSI hard disks would create device files like /dev/sda,/dev/sda1 /dev/sdb, /dev/sdb1 etc. Is this understanding correct?
In the case of USB attached SCSI devices, would driver create this device file entry? How is it created? Can somebody please tell me how it is being created automatically. In case I attach a fixed SCSI hard disk before boot up(and create device file /dev/sda1), would USB SCSI device driver create device files starting from /dev/sdb, automatically.
I have installed vmware in windows server 2003 enterprise edition. When I installed I changed the default installation folder from c: drive to i: drive, as I do not have space in c: drive. After I captured red hat linux cd in vmware and reached partitioning section and continued I got a message like "an error has occured no valid devices were find on which to create new file systems, please check the hardware for the cause of the problem". The machine is IBM server....
View 1 Replies View RelatedI'm kind of new to programming in Linux & c/c++. I'm currently writing a FileManager using Ubuntu Linux(10.10) for Learning Purposes. I've got started on this project by creating a loopback device to be used as my virtual hard disk. After creating the loop back hard disk and mounting it has the following configuration.
Code: $> sudo fdisk -l /dev/loop0
Disk /dev/loop0: 10 MB, 10977280 bytes
255 heads, 63 sectors/track, 1 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/loop0 doesn't contain a valid partition table Now what I want to do is develop a c++ program to read & write files to this loop back device,which I'm using to simulate an actual hard disk,at the blocks & sectors level. So far I've come up with the following code. But I'm still unable to read files from the hard disk one block at a time.
Code: #include <iostream>
#include <stdio.h>
using namespace std;
int main() {
char block[512]; int length=0;
cout<<"Implementation of the File Handler Read Method..."<<endl;
FILE *f = fopen("/dev/loop0", "r");
if(f == NULL) {
cout<<"Error In Opening the HardDisk File Retuning Error..."<<endl; return -1; }
//Read One Block of Data to Buffer length = fread(block, 1, sizeof(block), f);
/* Do something with the data */ cout<<"Length : "<<length<<endl;
return 0; }
When I run this Program All what I get is the message for NULL. "Error In Opening the HardDisk File Retuning Error...". So I could open the loopback device as a file an access it at the sectors & block level.
I have one hard disk (call her HDA) that contains nothing but a single ext4 partition containing a backup of all my important data. Last night I did a clean install of Ubuntu 10.10 on my primary hard disk (call her HDB) and from there proceeded to upgrade directly to Ubuntu 11.04 upgrade. In 10.10, I was able to read HDA just fine. However after the upgrade, I can no longer mount this drive. When mounting from file browser:
Code:
Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sda,missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so The end of dmesg said the following:
Code:
dmesg | tail
[ 82.130904] EXT4-fs (sda): bad geometry: block count 122096646 exceeds size of device (122096381 blocks)
my hard disk has a block count greater than the size of my device. I've done my background searching on this and tried a command line utility I've never heard of before:
Code:
# sudo e2fsck /dev/sda
e2fsck 1.41.14 (22-Dec-2010)
The filesystem size (according to the superblock) is 122096646 blocks
The physical size of the device is 122096381 blocks
[code]....
this is as far as I've gotten. This drive holds over a decade's worth of work for me and is extremely valuable. I really didn't think that the Ubuntu upgrade process would mess with this drive, seeing as the Ubuntu install was contained on an entirely different drive. What is it that I need to do to restore my drive to working status?
after installing Ubuntu on one WD 500 GB hard disk and after making mistake and pasting wrong code into Terminal:my OTHER WD 500 GB hard disk that was also in the system (I guess it was "hd1") - died.The problem must be, I guess, I typed wrong code: "hd1,1" instead of "hd0,0".)500 GB (NTFS) of data was on that other (non-Ubuntu) hard disk, and now I can not access it anymore. While booting, system gives "Hard Disk Error" warning and stops.One again: I installed Ubuntu od one hard disk and at the end of instalation I pasted wrong code for GRUB, giving address of another hard disk. Now that other hard disk has error and will not work

View 3 Replies View RelatedI had a dual boot (windows 7 + debian), both of them installed in my internal hard disk, with the GRUB in it. I have recently installed a second linux distro (mint), but I put it in an external hard disk. Now the GRUB allows me to boot any of the three operating systems, but I need the external disk to do it. It seems that after the mint installation the GRUB is now working from the external disk (if the external disk is not connected, the machine does not boot.) �Is there a way to change the location of the GRUB, to the internal hard disk of my laptop?
View 2 Replies View RelatedI have booted up from openSUSE 11.3 on a USB stick. When i go into Dolphin (the file explorer) and try to open a harddrive, I get the error:
Code:
An error occurred while accessing 'MyHardDrive', the system responded: org.freedesktop.Hal.Device.PermissionDeniedByPolicy: org.freedesktop.hal.storage.mount-fixed auth_admin_keep_always <-- (action,result)
My system decided to crash on me, hard. It was humming along happily for about 2 months and now doesn't boot. If I boot from hard-disk, I get grub. Launching the first kernel choice hangs. I thought maybe the install was corrupt, so I booted from usb install disk. The usb hdd didn't boot; something about an error trying to access /dev/sda . Unplugging the internal disk and plugging in the usb install disk does result in the system booting. Plugging in the internal disk in a running system usb-booted system does not result in the system detecting the disk.
How do I know if the disk is physically broken? This seems unlikely since it does manage to launch grub consistently. Or is this still possible? How can I try to mount whatever is left? The usb install disk doesn't even list the /dev/sd*. Any pointers on how to reformat the drive if it's not being mounted?
I 've just upgraded to Ubuntu 11.04 and I had a really hard time doing so. I have downloaded and burned the ISO, I restarted in order to install ubuntu and my computer booted from the disk drive, no problem so far.After I chose my language the purple screen with the option "Install Ubuntu" appeared and I highlighted the option and pressed "Enter". THEN, I got a black, empty screen while I was able to listen to my disk drive reading the disk.Everything was OK except for my screen.I thought there was a problem with the ISO or the disk itself. But, I 've tried different CDs and DVDs and I also downloaded the ISO several times. Unfortunately, I had always the same problem: disk drive working (making sound), screen-->BLACK-EMPTY. I was about to give up hope when I decided to turn on my desk lamp because it was getting dark. I was working on my last attempt and after I, once again, pressed "Enter" on the "Install Ubuntu" option I got the same dark screen as always but this time, because of the lamp, I saw that Ubuntu was actually being installed but the screen did not have any light. I managed to install it properly using my lamp to see what's going on on my screen but it's obvious that I can't possibly work that way. SO, how do I make my screen light come back so I can enjoy my new OS???
Note: My screen is working perfectly with windows so, it cannot be a hardware problem.
I was using Terminal and browsing a directory in my home folder. My "home" directory is located on "/dev/sdb1". When in Terminal I typed "ls" in one of my directories and the output was garbage. The output didn't show the files in the directory. I think it said something like, "input/output error". Unfortunately, I didn't write the exact error down. Instead I rebooted.The hard disk with the problem is:
Code:
$ sudo hdparm -I /dev/sdb

I just booted ubuntu from a disk that I burned to try and salvage some files off a hard drive with a failed boot sector (maybe. not sure what the problem is,). Anyway, I can see the files, and I have a large portable hard drive that I can use (a MyPassport 320gig, if I recall correctly). I'm having trouble accessing the drive, and I think it might be because there's something popping up in the task bar that I can't see. Unfortunately, I can't see the task bar! My screen's resolution is off, and I'm having trouble adjusting it. I browsed the various settings and I couldn't figure out any way to change it.
Is there anything I can do? EDIT: Oops! I didn't look into the Monitors options... how embarrassing.
EDIT2: Okay, looks like I can mess about with the resolutions, but all of them still deny me access to the full screen - still can't see the task bar.
If you have a hard disk image (including partition table, multiple partitions,...), is it possible to let Linux treat it as a regular hard disk?
By "regular hard disk" I mean I would like to have the image show up as, for instance, /dev/hdx and its partitions as /dev/hdx1,...
(I know I can mount one of the partitions in the image using "mount -o loop,offset=x ..." but I don't really like this option.)
I am on F15 32-bit with GNOME 3. I keep getting "A Hard Disk Is Failing" warnings from the Disk Utility, very frequently. Is this a serious issue? Because I knew this to be a bug in Palimpsest DU back in F13/14. Also how can I disable any notifications from this application?

View 2 Replies View RelatedI burned a Fedora ISO onto a CD and I love it. Now, I want to add it as a dual-boot to my hard disk. I divided Drive C into two (formatted) partitions one labeled Linux.During an attemped installation, I was able to find (thru "edit") the partition called "Linux." But one of the next questions threw me: it asked for a "mount point."I have no idea what that means (and yes I have readthe guide onthis site).
ACTUALLY... what I need to do is simply install into a partition I already set up.I don't find an option for that within the Fedora installation menu.I have 20 years of experience with Windows and try to keep up with everything, but Linux is totally new to me, so I don't understand the terminology.I also have been trying to find how to create a dual-boot situation from the hard disk, where XP is still my default (for now, at least).
Sometimes it may be necessary, or just convenient, to install Fedora from the DVD ISO file located on a local hard drive. The method I describe here does that, with two requirements. It uses GRUB4DOS, and the necessary files must be located on a FAT32 or EXT2/3/4 partition. Create the new partition and name it "FEDORA". It does not need to be a primary partition, and can be deleted later. An existing partition can also be used, but you will either need to change it's name as shown or put the correct name in the kernel line of the menu.lst file when that is created in step 5.
Use your favorite ISO program to open or mount the the DVD ISO image file and extract the /images directory to the root of the partition. Copy the DVD ISO image file to the root directory of the partition. Prepare a method to boot GRUB4DOS. See the following GRUB4DOS tutorial page for details about that task. [URL] Create a menu.lst file for GRUB4DOS with the following lines and place it in the appropriate location for your installation of GRUB4DOS.
Code:
title F13 DVD Install
find --set-root /Fedora-13-i386-DVD.iso
map /Fedora-13-i386-DVD.iso (hd32)
map --hook
root (hd32)
kernel /isolinux/vmlinuz repo=hd:LABEL="FEDORA":/
initrd /isolinux/initrd.img
Now just boot GRUB4DOS, select "F13 DVD Install" from the menu, and install away!
For the GRUB4DOS direct-mapping to work, the ISO file cannot be fragmented. If the partition is fresh (newly created), that shouldn't be a problem. However, using an existing partition will likely fragment the file, and you'll need to defragment it with a Windows utility (FAT32) first. I've actually only done this on FAT32, but EXT should work too, theoretically... Translation - use FAT32 on a new partition.
