Need to resize dynamic system partition on Windows Server

Dynamic disk is another disk type, different from basic disks. It offers more advantages such as larger capacity support and fault-tolerant ability. Many users have installed the Windows Server on the dynamic disk to enjoy the its advanced feature. However, like the C drive on a basic disk, the dynamic system volume is also easy to get full after a period of time.

"I have a Windows 2008 Server with a dynamic disk that has 70 GB of free space. I would like to extend the C drive into the unallocated space (notice that they are not next to each other) so that I can increase the C drive size. Is this possible? Help, please!"

If you are planning to resize dynamic system volume on Windows Server 2008 and later versions, you can use the “Extend Volume” and “Shrink Volume” features of Server Disk Management.

Step 1. Right-click the target partition and select "Extend Volume".


Step 2. In the pop-out wizard, click "Next".


Step 3. Select the disk with free space to extend volume and click on "Next".

Step 4. Then wait for the process to be done. Finally, click on "Finish".
