With the release of the 5.5 series of VMware products comes the ability to expand a single VMDK above the 2TB limit. However, there are some limitations/requirements you should be aware of first.
- To expand a VMDK above 2TB the Virtual machine must be version 10. (Warning: Read about Version 10 virtual machines before you upgrade to them!)
- Version 10 virutal machines can only be managed using the vSphere Web Client. (Not the traditional vSphere Client)
- Datastore formatted in VMFS-5.
- To use the vSphere Web Client you require a vCenter server. (Windows and Virtual appliance will work fine)
- This effectively makes expanding VDMK files above the 2TB limit a paid only feature.
- It should go without saying, the VM OS needs to support a volume larger than 2TB. (e.g: Windows GPT volumes)
- You can create a new VMDK larger than 2TB with the VM powered on, but if you are increase an existing VMDK above 2TB you need to power the VM off.
Once complete, power on your virtual machine and expand the volume within your OS. In my case it was a Window Server.
Enjoy your new free space goodness. 🙂
