Expand disk space on Ubuntu 10.04 (VMWare Guest)

Question

I need to resize the disk space of an ubuntu guest in VMWare Workstation. After using the expand disk utility in vmware workstation, I need to do some linux magic to resize the parition. I have searched and found a lot of posts about resizing it. Unfortunately I don't really understand it all that well. Can anyone help me out with this?

I really appreciate the help.

Solution 1

Ok, so after much toiling I finally figured out how to do it. And again, gparted cannot be used. Firstly, you should expand the size of the disk in VMWare Workstation. Boot into a livecd and open a root terminal:

We need to create a new primary partition of type LVM out of the free unused space.

#fdisk /dev/sda
#Command (m for help): n
#Command (m for help): p
#Command (m for help): 3
#Command (m for help): w

Reboot the vm into the live cd again

Create the phyisical volume:

#pvcreate /dev/sda3

Add the new volumn to the group:

#vgextend ubuntu /dev/sda3

Find out how much free space you want to expand to

#vgdisplay

Check what "Free PE/Size" equals and use that value in the next command

Extend the lvm and grow the file system into the new space

#e2fsck -f /dev/ubuntu/root
#lvextend -L +12.6G /dev/ubuntu/root
#resize2fs /dev/ubuntu/root

Done!

Solution 2

Back up your machine. Boot the system with GParted and grow the partition. Apply the changes.

gparted doesn't work on lvm's. If you look at my post... sda1 is an LVM.

[WheresAlice]

+1 that sounds about right, or given this is all virtualised you could have just added a second disk and extended the lvm to that disk.

[WheresAlice]

-1 It's running LVM and is virtualised, extending partitions with GParted is not the solution in this case.

+1 People who search for things like "vmware ubuntu increase disk size" will come here. The answer is helpful for some of those.
