Solution 1

You can increase the size of the virtual machine's disk capacity with the command-line tools provided with VMWare:

/usr/bin/vmware-vdiskmanager -x 28GB /path/to/VM_Name.vmdk

replacing /path/to/VM_Name.vmdk with the path & name of your virtual disk file.

Then, increase the virtual disk with a GParted bootable ISO (boot from it with the VM).

Full guide found here.

Solution 2

Move /home and /swap to separate virtual disks (VMDKs). There's no reason to keep them on the same VMDK; virtual disks aren't a scarce resource!

This also gives you a bit more flexibility -- you can put /home and /swap on different storage, for example.

You will need to edit /etc/fstab to change the lines for /home and /swap to point at the new disks. If you look at /etc/fstab, you will see lines like

/dev/sda2     /home   ext3   (various options)
/dev/sda3     none    swap   (various options)

If you move /home to disk #2 and swap to disk #3, change /dev/sda2 to /dev/sdb1 and /dev/sda3 to /dev/sdc1.

Note that if you used LVM for your disks you would not have this problem; LVM logical volumes do not need to be contiguous on disk (or even on the same disk!)

I am using Ubuntu 9.04 in vmware for my programming purpose. I previously had 12GB of virtual harddisk, my partition scheme was as follows,

8GB Primary Partition for (/)

2GB logical extended partition for home

2GB logical extended partition for swap

Now I need 20 GB more space for my (/) Partition. So I added 20GB to my virtual harddisk so now, my partition scheme was as follows,

8GB Primary Partition for (/)

2GB logical extended partition for home

2GB logical extended partition for swap

20GB unpartotioned space.

can you please tell me is it possible to make my Primary partition (/) to 28 GB, If yes tell me how?

It would be great if you can tell me some GUI software, otherwise for commandline please elaborate little more. :)

Thanks.

Thanks you very much for your answer John T. I have one question that is there are two extended logical partitions between free space and / partition, How can I join first and last partition.

You can move the partitions and then merge them with the partition you want to expand.

Upvoted for mentioning LVM.

It worked. Downloaded GParted bootable iso, moved other partitions. increase size of root partition. Thank you very much for introducing me to such a useful tool.

This would have been "Switch to LVM" if it weren't for this being a VM. For a VM this is better than LVM.
