VirtualBox increase from 20gb to 40 gb
 

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.

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

I booted in to gparted but could do nothing with the /dev/sda2 which is lvm2. I deleted the partition /dev/sda3 that I created and I now have 20 gb of free space which is where I was after I make the disk larger in VertualBox. I can make the free space either Primary or Extended in gparted.

VertualBox still shows the disk 40 gb which /dev/sda is but I can only use the 19 Gb that is on sda2.

Any help appreciated as I have working on this server for so long. It is at home not a work server so it is personal :)

fdisk /dev/sda with the p option gives this

Command (m for help): p

OK this is what I did to solve the problem.

I made a Clone of the VM then did the following.

1. I used fdisk to change /dev/sda2 from lvm to Linux
3. Shut down the VM and booted into Gparted
4. I deactivated sda2 and increased the size by all available space (Still showed as lvm at this stage)
5. I reactivated sda2 and shutdown Gparted.
6. I booted into the VM
7 fdisk shows the following:

Disk /dev/sda: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders

Everything looks OK and I can open the web server and see the files....

I think that the problem is fixed, and I take no responsibility if you try and it fails to work :)

EDIT: This did not fix the problem just looked like it did. I deleted it all and started again
