The necessity of extending partition on Windows Server 2016
Windows users may know that the partitions are not divided perfectly at the first time. As time goes by, there are chances that that some partitions are too small for storage data, while some partitions are too big to waste a lot of space. And system partition running out space can cause whole operating system run slowly.
In such condition, you may want to re-partition the disk so that the space can be used more reasonable or enlarge system partition to speed up operating system.
Extend volume on Windows Server 2016 with three tools
You can use three different useful tools to extend partition in Windows Server 2016. If a contiguous unallocated space behind the partition that you want to extend is available, you can choose the first or the second second. If not, employ the third.
# 1. Enlarge partition on Windows Server 2016 with Diskaprt
Diskpart is the built-in tool for Windows users to manage their disks with command line. You can use it to extend partition for Windows Server 2016 easily. Press “Win+R” and type “diskpart” to open the CMD. Then, type the relative syntax to extend the partition:
Type the parameters above, it will shown as the next screen shot, and you may extend the volume successfully.
However, if there is no unallocated space contiguous to the volume you want to extend, this syntax will be invalid.
#2. Enlarge partition on Windows Server 2016 with Disk Management
Windows Server 2016 is the latest operation system of Windows Server. It has the tool Disk Management. You can use it to resize Windows Server 2016 partitions with the Extend Volume and the Shrink Volume.
To use Disk Management to extend volume, you need to right click the partition you want to extend (here we extend the system partition), select Extend Volume to get into this wizard to extend it step by step.
However, sometimes when you open the Disk Management to resize the partition, the Extend Volume is grayed out and you cannon use it. As Extend Volume of the Windows Server 2016 Disk Management still asks there must be unallocated space behind the partition and adjacent to it. If there is no unallocated space nearly to it, the Extend Volume would be grayed out like the following picture, so that you cannot extend volume for the partition.
Then, what should you do when the Disk Management and Diskpart unable to extend volume in Windows Server 2016?
