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!"

Resize dynamic system partition via Disk Management

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. But you should keep in mind that the “Extend Volume” only works when there is an adjacent unallocated space behind the target volume, otherwise, this option will be greyed out. If your disk partition layout meets the requirements, take the following steps:

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

Extend

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

Next

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

Select Disk

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