Oracle VM VirtualBox from 20gb to 40 gb

[Dingo-Den]

I have Window 7 Professional with Oracle VM VirtualBox version 4122 r80657 with Linux Centos 6 Servers.

I increased my Oracle VM VirtualBox from 20gb to 40 gb.
I tried to copy a large folder from my old Centos 5 Server to this new Centos 6 server and it said there was not enough space.

When I look at the machine its says under the Drive information:

Type Normal (VDI)
Virtual Size 40 GB
Actual Size 14 GB
Details Dynamically allocated storage.

df -kh .

I created /dev/sda3 and it is empty and when I look in fdisk I see this

Device Boot Start End Blocks Id System
/dev/sda1 * 1 64 512000 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 64 2611 20458496 8e Linux LVM
/dev/sda3 2611 5221 20966162+ 83 Linux

So my question is how do I make so that I can increase the LVM drive with the empty space on sda3 ???

I am new to linux so need help. I think I am doing something silly or missed something somewhere but any help would be appresiated.

Cheers

Moving this discussion to "Linux Guests", since the Windows Host is not relevant to the question asked.

Anyway, when you increased your disk size that was all that was increased. The partitions on the disk were unchanged. You need to use a partition manager inside the guest to manipulate such things as partition size. Unfortunately your choice of LVM partitions complicates this: typically one would boot up the VM with a gparted live cd, but I don't think gparted supports LVM, and I don't know what does.

I just installed Centos 6 and it made up the directory structure. The only thing I did was increase the size and add a new device sda3. I installed gparted on the virtual pc and I did not know what to do it just seemed to view the disks and had an option to delete? I could see the following drives in gparted

Partition File System Mount Point Size Used Unused Flags
/dev/sda1 ext4 /boot 400MiB 70.02 429.98 boot
/dev/sda2 ! Lvm2 19.51 GiB ---- ------ lvm
/dev/sda3 ! Unknown 19.99 Gib ---- -----
Unallocated Unallocated 5.23 MiB ---- -----


I have spend four days moving a Centos 5 Web Server over to this VM Centos 6 and I hope that is not all gone to waist.

I did not create the boot disk of gparted and that is the bit I missed but as you say it does not change lvm drives but I hope out there somewhere somwone has a solution.

I am new to Linux but I can usually follow direction

You're asking at the wrong place. Extending the partition is OS specific and should be addressed at the forum of the OS.

Google change partition size linux lvm or ask the CentOS forum.

OK I have moved on and this can be marked as resolved.
