VMWare, disk space

I uploaded a VM onto my host.

It came with about 40GB disk space on a RHEL system

Is there any way to go to the datastore, give the VM more disk space, which could then be used by the VM, or is this a lost cause

How to Resize a Partition after Disk Expansion

To re-size a disk, select the Virtual Machine, Select Edit Settings, Highlight the Virtual Hard Disk, and select Edit there is an option to increase size. This only changes the physical size of the virtual disk, it does not grow the partition on the disk. See below.

Before making any changes to the partition structure of the disk, ensure you have a full backup, not a snapshot.

1. Resize partition with Gparted Live CDROM

i. Download Gparted Live CDROM (http://gparted.sourceforge.net/livecd.php).

ii. Upload the cdrom iso to the vSphere ESX/ESXi datastore.

iii. Mount the cdrom or iso on the virtual machine.

iv. Shutdown and restart the virtual machine booting from the cdrom.

v. Select Resize partition.

Here is a Tutorial Walkthorugh of how to resize a partition with a GParted Live CDROM



2. Using DISKPART.exe

(the system disk cannot be re-sized within the virtual machine, but other disks can be resized, eg. D: E: etc

i. Shutdown the virtual machine.
ii. Remove disks from virtual machine (but do not delete them).
iii. Add the disks to another virtual machine.
iv. Start up virtual machine.
v. Use Diskpart in the OS to extend disks.

see here for details on Diskpart usage
