In this article, I will solve the below Windows Server Issue
Error extending volume: Size Not Supported
Scenario
When I tried to Extend Volume for a specific drive in Windows Server 2012 R2 by opening
- Server Manager > File and Storage Services.
- Navigate to Disks > (I have unallocated free space (19.5GB)).
- Right click on C Drive > Select Extend volume.
- The following dialog will be shown to set New size.
- When I set the New size and clicked OK, I got “Extend failed” as shown below:
- I clicked on Extend failed to find out the reason, I got
Error extending volume: Size Not Supported
Cause
The “Error extending volume: Size Not Supported” usually occurs because of there is a partition/drive between the original partition and the unallocated space. Thence,
If you want to extend volume, you should make sure that there is no partition between the original partition and unallocated space.
Solution
In this case, you will need to unallocated the drive space beside the operating system drive. but this means all data in this drive will be deleted!
So before you getting started, you should
- Make sure that the unallocated space is greater than the F:\ drive (the drive beside OS drive) size to ensure that you can move the F:\ drive content to this space.
- Create a new volume from the unallocated space.
- Move the data files from F:\ Drive to the New Volume.
- Delete F:\ Drive.
- You are now having unallocated space beside the Operating System drive.
- Again, try to extend the Operating System drive that should be now extended properly.
Applies To
- Windows Server.
- Windows Server 2012.
- Windows Server 2016.

I had a similar problem…..In my situation i had an extra volume (in my situation was the extra volume was called (F:) between the (C:) volume (the volume that i was planning to extend) and the unallocated space). I deleted the (F:) volume, and then i could extend the (C:) volume. Apparently there should be no volumes between the the (C:) volume and the unallocated volume.
