I am trying to expand my Ubuntu partition into my Windows 7 C: drive, but the win7 partioner will not let me shrink it because of immovable files. Is there anyway for me to but an loopback device in the windows partion, and have Ubuntu boot with that as the root device?

Recently installed some minor software, some games and Ubuntu Tweak, I am not sure if that's what caused this issue or not. I shutdown after the installations, then when I tried to start back up the small, white ubuntu logo appears just like it normally does, then it just goes to a black screen. I turned off the computer and restarted in (Recovery Mode). It goes about its thing then it says it is waiting for root file system, then after about 30 seconds it says "Gave up waiting for Root File System" how to fix this without reinstalling?

I have extracted the WebCamStudio java application into a folder in my Fedora 13 x86_64 installation. I can run WebCamStudio with the command java -jar "WebcamStudio.jar".
I can successfully select sources and view preview etc. However, the bottom status line permanently states "no output". There is no vloopback device to select in Cheese, camstream, Skype, AMsn etc. Does anyone know how I can get the loopback device to work?

I was wondering if it is possible to create a growing image for a loopback device. Like a file that you create that will grow with the data that is placed on it instead of a file that has to be the size of the entire file system?
View 4 Replies View RelatedWe�re experimenting with deploying SUSE 10 SP3 systems and adding them to a Windows domain and DNS. Oddly, when we register in DNS, it gets registered under two address: the real IP address, and the address 127.0.0.2. Also, an ip addr command shows that the loopback device lo has two addresses: 127.0.0.1 and 127.0.0.2.
The above behavior is just on SP3. On SUSE 10 SP2, the lo device has only the 127.0.0.1 address, and the system is able to register correctly in DNS.
Do you know what the 127.0.0.2 address signifies, or how to get rid of it?
I'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'm trying to run a persistent Debian distro on a USB thumbdrive, with the persistency data written in a mounted live-rw loopback file. However, the drive has to be formatted FAT32, and that poses a 2GB maximum limit on files, so I can't use the full 3GB space that is left on the drive after the Linux install. Can I make two loopback files and format/mount them as a single filesystem? If I can't I guess I'll have to repartition the drive, which I'd rather avoid.

I haven't changed anything on the system as far as I'm aware, and I ran some HD diagnostics and everything seems fine. however when I try to mount the drive with the following command:
sudo mount -t ext3 -o rw /dev/hda1 /mnt
I get the following error:

I used the ntfs-config utility to mount my windows drives automatically at startup. While doing so, I had my USB-HDD still attached, and after making changes and rebooting, it did something unknown I didn't expect and I cannot mount my USB-HDD again, and it gives me the following error message:
Error mounting: mount exited with exit code 1: helper failed with:

I did manage to open it somehow, but then all the data was erased apart from ~3 GiB [edit: it's got some kind of extra drive built-in which is mounted as a CD-ROM drive, and when I open that one first all the files are missing in the actual drive, otherwise I get the message above]. I don't know what information I should include here, but my fstab looks like this:
# /etc/fstab: static file system information.

This line in terminal:
sudo mount -t ntfs-3g /dev/sdb1 /media/sdb1
Gives:

Currently, when I connect it, it gets mounted by the gvfs (Gnome virtual file system) at ~/.gvfs/iPhone.

I don't know how I can get this to work.

View 3 Replies View RelatedI'm developing a little script that automatically detects the insertion of a usb device and tries to open the directory of this device in nautilus. I am using Python
So far I was able to sample and compare the changes that occur in the output of 'lsusb' command and get information pertaining to the addition and removal of usb devices.
Now I want to know if we can use that information (or some other info present in the usb sybsyste --/sys/bus/usb folder) to determine exactly where this device has been mounted.
I know you might recommend using 'mount' as a quick way to do the same. I have already done that, but the limitation is that mount only gives u the mountpoint information. How does one (using a program/logic) determine which mount point corresponds to which device.
If I were to plug in two devices together, and both were automatically mounted, how will I be able to tell which mountpoint corresponded to which device? the output of lsusb provides no information whatsoever about where the device is mounted. So its kind of a deadlock
from lsusb ive been able to gather : Device name, serial and bus number and device number
Another thing i've noticed is the 'autoplay'. Whenever I insert a my music player into my computer, it gets mounted automatically and I'm presented with options about simply opening the file or playing it with rhythmbox... now if all that was being done was polling the output of mount, they would not be able to know that the device inserted was a music player (that info u can get from the /sys/bus/usb folder only using the device class and subclass info). So obviously the two are linked somewhere...

I installed ubuntu on my MacBook Pro, and now I get the infamous "still waiting for root device" when booting mac os x. I couldn't find any solutions that worked (macbook pros don't have a BIOS, or any drives that are easily removable). Anyway, so I have ubuntu working, and I need some files from OS X before I would consider reinstalling, etc. So I mounted the drive, went to users, etc. and it says that "I don't have the permissions necessary to view the contents of ****".
I did chmod 777 /media/os x/Users/* but that led to "Could not access: No such file or directory" (there's a space between os and x, I think it counts it as two commands or something and I can't rename the drive). Any way to give myself the permissions to access my files, or maybe just to copy over the whole hard drive to my main computer, or maybe somehow solve the "still waiting for root device".

Spurious ACK on isa0060/serio0. Some program might be trying to access hardware directly.
I am or was using Hardy.
It seems to me that the program is telling me it can't find the hard drive or the partition where the OS resides. I have my drive partitioned with into sections for booting, the OS and my Home directory.
this is my first setup of ubuntu. And I�m quite familar to Linux allthoug it�s been a while since my last setup. Anyway, my system is brand new and consist of the following parts:
AMD Athlon X2 240e on MSI 880GMA-E45 (SB850)
4GB RAM (DDR3)
All drives connected by SATA using onboard SB850 ordered by:
1 LG BluRay optical drive
2 WD Caviar Green WD10EARS 1TB
3 WD Caviar Green WD20EARS 2TB
4 WD Caviar Green WD20EARS 2TB
5 WD Caviar Green WD20EARS 2TB
6 WD Caviar Green WD15EARS 1,5TB
I set the SATA controller to AHCI because I want to set up a software raid (level 5) on the three 2TB-disks. The first disk (1TB) should be the ubuntu boot disk (no raid). The last one (1,5TB) is currently not connected - it will be added later. First I struggled booting the ubuntu server 10.10-CD (x64) from the bluray drive - after succesfull starting the setup procedure it told me that it cannot access the drive. It seems that drivers are missing. No problem - I connected an usb dvd drive to the system and gave it a try.
The boot order was set to usb-dvd, then bluray, then the first harddisk (1TB). Setup seems to run fine using the usb dvd drive. I�ve chosen the first disk (shown as /dev/sda) for the installation. It was automatically configured as one big root-partition and a small swap-partition. Grub was installed on the MBR of the first disk. But after restart GRUB tells me "Gave up waiting for root device" and "ALERT! /dev/disk/by-uuid/whatever does not exist. Dropping to a shell!". Obviously the boot loader cannot find (or access) the volume containing the kernel.
I made some research and found some other people complaining about some mixup of hdaX and sdaX devices on SATA devices - but these statements where from 2007. Another point is that the USB optical drive is my boot device while the installation runs, but not afterwards - does this matter? I also tried installing Ubuntu server 10.04, but is behaves the same. Please keep in mind that the goal is to have ubunto server 64bit running on this system - that�s it. No dual boot is needed. And there is no data on any disk that should be taken care. It�s a very new system. Where should I start to fix this issue? What�s wrong with the current linux boot loader using SATA disks connected to SB850 SATA controller?
