How to Fix “Size Not Supported” Error in Server 2012?
Meet the “Size not supported”error when trying to extend or shrink a partition in Windows Server 2012? Relax, here we will tell you why and how to resize partition more flexibly in Server 2012.
Overview of “Size not supported” error during resizing partition
Situation 1: I’d like to increase the C drive partition space on the Windows Server 2012. It is 40 GB and I have only 50MBs left. There was no unallocated space so I deleted the data partition in order to create some space. However, when I try to extend C drive I get the error message: Error extending volume, size not supported. Any help will be appreciated.
Analysis: After using Windows Server 2012 for a couple of years, you will find the system becomes full. You are likely to get low disk space warning when installing some large-size applications. It is imperative to extend system drive under this circumstance. Deleting data partition and then extend system partition with that space is workable solution. Nevertheless, you may get above error randomly. The solution is deleting the adjacent partition in “Computer Management”, and then you are able to extend the volume with contiguous unallocated space.
Situation 2: When I try to shrink partition size to smaller capacity using PowerShell cmdlet, it gave me an error says, Resize-Partition: Size Not Supported. What does that mean? And how can I resize the partition size successfully? Thanks.
Analysis: When you encounter this error which probably means you try to shrink this partition to smaller than current used space. Shrinking or extending could be confusing in PowerShell because it uses different unit byte instead of MB. You can input “SizeMin” and “SizeMax” to identify how much space you can shrink by and then redo the task. Alternatively, you can do all of operations in simple, graphical and neat interface of some third party tools.
