Topic: Redimensioning virtual disks

redimensioning virtual disks
I download the iso of Gparted to mount as the CD/DVD device in virtualbox
when I try to resize I obtain an error. Even i don't know how can I recover or document this error from inside the virtual machine.
i put screenshots of my tempts.
best regards. Nice to be here.

No screenshots allows me the forum.
The message i received is :
"Ocurrió un error al aplicar las operaciones"
Errro applying operations

Perhaps you know the frequent error messages when resizing virtual disks. i have space not assigned from my original disks of 10 GB and i would like to become in 50 GB. I have apply the command from virtualbox :

Y:\VirtualBox\Data\Machines\WindowsXPpro-btwinVA-COMUNICACIONES Clone\WindowsXPpro-btwinVA-COMUNICACIONES Clone-disk3.vdi

Vboxmanage modifyhd "Y:\VirtualBox\Data\Machines\WindowsXPpro-btwinVA-COMUNICACIONES\WindowsXPpro-btwinVA-COMUNICACIONES-disk3.vdi"  --resize 50000

how can I document the problem to put the result here. please a detailed tutorial i am a dummie.
How can i solve this problem. I need to make the disks bigger.

best Regards

Re: Redimensioning virtual disks

Would you be able to provide the gparted_details.htm log file?

See Saving GParted Details.

Re: Redimensioning virtual disks

I have done this exactly :

Copying to Hard Drive Partition

    Create a mount point directory by entering:

    user@debian:~$ sudo mkdir /tmp/myhd

    Mount the hard drive partition. For example, to mount the first partition sda1:

        To mount an NTFS partition, enter:

        user@debian:~$ sudo mount -t ntfs-3g /dev/sda1 /tmp/myhd

        To mount other partitions, such as ext2 or fat32, enter:

        user@debian:~$ sudo mount /dev/sda1 /tmp/myhd

    To copy a file, such as /root/gparted_details.htm, enter:

    user@debian:~$ sudo cp /root/gparted_details.htm /tmp/myhd

    When you are finished copying files, unmount the hard drive partition by entering:

    user@debian:~$ sudo umount /tmp/myhd


Where can I find myhd outside the virtual machine ?
or where is the tmp folder ?

Best Regards

Re: Redimensioning virtual disks

The virtual machine is under windows xp pro
and the host with w7-64
I have empty the cd unit to enter in the virtual machine. I received notice in the trayicon of a new disk, but I can't find.

Re: Redimensioning virtual disks

If the partition /dev/sda1 was mounted on /tmp/myhd and that is where you copied gparted_details.htm, then the file is at the top level of that partition.  For example if your virtual machine normally mounts /dev/sda1 at "/", then the file is available at /gparted_details.htm.

You can learn where GNU/Linux automatically mounts partitions by looking at the contents of the file /etc/fstab in your virtual machine.

I am not a linux user. I have a ubuntu virtual machine and a very basic knowledge.
If I have windows systems i don't understand the /etc/fstab in my virtual machine
The way gparted sees the partitions and the name of the disks is not equal in windows.
When I shutdown gparted i only can see - i supposed so - in the windows partitions.
Where is that file ?
I don't know.
I'll try now to locate with the windows search option under xp.
And comment
best Regards

Re: Redimensioning virtual disks

Thank you for posting the gparted_details.htm log file.  The problem is listed at the end of the log:

     Parted can't resize partitions managed by Windows Dynamic Disk.

Unfortunately Windows dynamic disk partitions are not well understood by the open source community as Microsoft does not freely publish the specifications.

This is a known problem.  See also Bug 634668 - Resizing of NTFS fails if partition type is 42.

If you need to resize a Windows dynamic disk, then unfortunately GParted will not work for you.  You might try searching for other tools that might handle resizing Windows dynamic disks.
