This article introduces how to extend volume with Windows Server 2008 R2 Disk Management, limitation of Server 2008 Extend Volume function and better method.

Precondition of Server 2008 Extend Volume function

Most of Windows 2008 servers have running for several years, so it is very common that disk partition runs out of space. With right partition tool you can extend partition without losing data. Therefore, you can solve the low disk space issue fast without wasting a long time to recreate partitions and restore from backup.

Some people like to use Windows native tools, when extending volume in Windows Server 2008, there is indeed a built-in Disk Management tool. Better than previous server 2003, Windows Server 2008 added new Shrink Volume and Extend Volume functions to help resize disk partitions without losing data.

However, Extend Volume only works under very restricted conditions. If your disk partition configuration does not meet one of the requirements, Extend Volume is grayed out and you cannot extend volume with it.

Windows Server 2008 Extend Volume requirements:

  • The volume that you want to expand must be NTFS or RAW (without any file system).
  • There must be adjacent Unallocated space on the right.

Therefore, Disk Management can only extend a NTFS volume by deleting the right contiguous partition. In addition, the partition you that you want to delete and extend must be the same type (both are Primary or Logical).

In my server, Extend Volume is disabled for all disk partitions, because:

  • There is no adjacent Unallocated space to C: drive.
  • Unallocated space is on the left side of E: drive.
  • D: drive is FAT32, which is not supported.

Better method to extend Server 2008 volumes

In most of servers, administrators want to extend C: drive, but they cannot delete the right contiguous volume D, because programs or some Windows services are running from it. Even if they can extend volume by deleting other one, there must be another partition or disk to transfer files.
