I have done a resize on my Windows VM to increase the disk size, but in the VM console it does not show that it has resized; even though the OnApp UI does.
Windows Virtual Machines
All OnApp versions
Inside of the VM, go to the Disk Management section.
You should see your primary partition and an unallocated partition as large as the increase that was made to the disk.
Right click on the primary partition and run the extend option. Once this is done, the two partitions will be combined to the expected size.
Note: Before making any disk related changes, we recommend creating a backup as a precaution.
As of yet, OnApp cannot extend a Windows partition as a part of the resize disk task.
