Issue/Introduction
Symptoms:
After extending a Windows partition using the Microsoft Diskpart command-line utility or Disk Managements (diskmgmt.msc), you experience these symptoms:
- The Windows server guest operating system (Guest OS) shows an incorrect disk size in Disk Management or on My Computer after you expand the disk.
- The vSphere Client and vSphere Web Client display the correct, increased disk size.
- Within the Windows guest operating system, you see:
- Disk Managements (diskmgmt.msc) displays the correct, increased disk size.
- Share and Storage Management (storagemgmt.msc) does not show increased size of the disk.
- The partition size does not get updated.
- The old partition size is retained.
Cause
This issue occurs because the NTFS driver exhausts its resources when it tries to extend the volume.
