Resize disk in VMware changes the virtual disk size, but it does not change the OS Partition.


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

If you are using LVM filesystems, you should create a new partition, add it to the Volume Group, extend the Logical Volume and then resize the corresponding filesystem.

Another solution is to use a GParted live CD to increase VM disk size.

As this is a very common problem, there are lots of how-to docs in the internet [0] [1]

You should have a backup copy of your VM, in case something goes wrong.
