    vmkfstools -X fails to expand VMDK file

    Bill Oyler Enthusiast

      When I attempt to exapnd a VMDK file using vmkfstools -X, I get the following error message:

       

      Failed to extend disk : The file specified is not a virtual disk. (15)[/b]

       

      However, I am certain that the file I specified is in fact a VMDK file.  Have things changed in 3.0 such that this method no longer works to expand a VMDK file?

       

      The VMDK file is located on a standard VMFS 3.0 partition.  Here is a complete copy and paste of my command sequence:

       

      \[root@lab-esx2 VM1]# vmkfstools -X 8G VM1.vmdk

      Failed to extend disk : The file specified is not a virtual disk. (15)[/b]

       

      The current size of the VMDK file is 6GB.

       

      Thanks to anyone who can help solve this mystery!

       

      Bill
