Extend a Partition on Windows Server 2003

Filed Under (Windows Server 2003) by on 11-07-2006

I know most of you have done this time and time again but I always forget the steps on how to extend a partition on Windows Server 2003. Now I can always just take a look here to remind me what I need to do.  [:P]

  1. At a command prompt, type diskpart

  2. Type list volume to display the existing volumes on the computer

  3. Type Select volume # where volume number is number of the volume that you want to extend.

  4. Type extend to extend the partition the remaining free space

This method works great if the storage is local or stored on SAN like an HP EVA.

    Won”t work on my hardrive in Windows 2003 server. Says partition cannot be extended.

    Is there free space left on the disk you are attempting to extend? The example above was used for extending a drive that was created on a SAN after I allocated additional space to it.

    You cannot extend the system drive using this method.

    IF extending data partition is sucessfull in disk management but it does not show up in Windows Explorer
    Then Use FSEXTEND to resolve the issue….
    Download FSEXTEND
    Copy it in a Folder
    OPen CMD Navigate to that folder
    Run FSEXTEND driverletter: and press enter
    (MAke sure that you are on a different partition than the one you are trying to extend)

    You can extend a Windows 2003 server system using a Vista workstation.
    Open system manager on the Vista workstation. Connect remotely to the windows 2003 server with system manager.
    Open disk manger and right click on the partition you wish to extend and click extend.

    Use EAESUS Partition Manager Server Edition.

    Use the extend command to incorporate unallocated space into an existing volume while preserving the data.

    The following are the requirements for the extend command: • The volume must be formatted with the NTFS file system.
    • For Basic volumes, the unallocated space for the extension must be the next contiguous space on the same disk.
    • For Dynamic Volumes, the unallocated space can be any empty space on any Dynamic disk on the system.
    • Only the extension of data volumes is supported. System or boot volumes may be blocked from being extended, and you may receive the following error:
    Diskpart failed to extend the volume. Please make sure the volume is valid for extending
    • You cannot extend the partition if the system page file is located on the partition. Move the page file to a partition that you do not wish to extend.

    I have also tried the demo of EAESUS Partition Manager Server Edition which is so simple and easy for me. So, I decide to have a try of its full version. Try the demo here:http://www.partition-tool.com/download.htm

    Just used the diskpart on W2K3 to extend the partition after adding 3 146 gig HDDS. Works w/o flaw IFF the extended partition does not contain the pagefile as noted above.
