I had a Windows 2003 R2 server running virtually that I had removed a bunch of data from and I wanted to compact the Virtual Data drive. When I shutdown the server and tried to compact the drive I received this error. “The system failed to compact ‘C:\ClusterStorage\Volume2\storage\F_2010-06-07T204253.vhd’. Error Code: 2424869” The fix was simple and that was to start the Virtual Server back up and remove the Shadow Copies on the drive that I was trying to compact and shut the server back down and then it would allow me to compact the drive no worries.
Til later just Roger
