Question from
I have a Windows Server 2008 Datacenter. i have one disk with the partitions below:
C: 20GB simple basic system, boot, ,active, primary partition
D: 50GB simple basic logical drive
E: 50GB simple basic logical drive
F: 60GB simple basic logical drive
G: 44GB simple basic logical drive
I want to extend system boot volume C, I shrunk volume D and there is now ‘free space’ with green color in computer disk management window. I do right click in C volume to click “extend volume” but it is not active..!!!! why is it not active and I can’t extend it?
And now what should I do to having more space on C? Pls advise me how to proceed…. my C drive is full, there is only 700MB free on it. Thanks in advance…

No matter what operating system you are using, the disk layout may not be reasonable after a period of time. So does Server partition layout. For example, the system partition requires more disk space for a smooth running. In this case, the first solution you can find is to ask help from Disk Management.
However, just as the author said in the above question, Extend Volume is not active due to some reasons. Then how to extend volume Server 2008? Actually, resizing server partition is not as difficult as you have thought. Next we will discuss how to resize Server 2008 partition size by using free Windows Disk Management and Server 2008 partition manager.

Two Ways to Resize Server 2008 Partition Size

Take extending and shrinking Windows Server 2008 system partition for example.
Way 1: Use Disk Management
Step 1. Right click My Computer, select Manage, then Disk Management, there all Server disks are displayed.
Step 2. Right click on the system partition you want to resize and check whether the Extend Volume and Shrink Volume options are active. Normally, Shrink Volume is always available, but Extend Volume is always grayed out. Check out why.
If you are able to use Extend Volume and Shrink Volume, then just enter the wizard and follow the guidance to complete the operations. If Extend Volume is inactive, then you should do either thing: to delete the partition that is following the C drive, and then retry Extend Volume. Or you can choose to use Server 2008 partition manager which is a more flexible way.
Note: Since Windows Server 2008, Disk Management offers Extend Volume and Shrink Volume features. That is to say, if you are using Server 2003, Disk Management is unable to help resize Server partition unless you delete a partition and then recreate. See how to resize Server 2003 without data loss.
