Expand a VMWare Virtual Disk Size

December 28th, 2007 | by RoarinPenguin |

Regardless of VMWare Version you’re using, you should have the command line tool

vmware-vdiskmanager

This useful command line tool can be used for many operations (vmware-vdiskmanager --help) including expanding a Virtual Disk without losing data contained.

The syntax for expanding is:

vmware-vdiskmanager -x 36Gb virtual_disk_name.vmdk

If you have partitions within the disk, remember that the tool expands just the size of the disk, NOT the size of the partition; if you need to expand the partition size, please use some third party tools (more info here).
