Unable to Extend C Drive for Thin Provisioned Disk

Setup
  • VMware vCenter 5.1
  • ESXi 5.1


 Discoveries
  • When the VMDK is created as Think provisioned disk it doesn’t allow to extend the size of vmdk in VM Edit Settings and it displays greyed out
  • Additionally if you have taken snapshot of the Thin provisioned disk. The option will be greyed out until it is removed  

 Resolution/WorkAround
  •  Perform Storage vMotion and change the disk to Thick Provision which will enable the option to extend the size of vmdk in VM Edit Settings
