Supposed that you had a 100GB LUN in a 200GB Volume on a 1TB aggregate. Neither the LUN nor the volume are set to auto-grow. The LUN has been sitting at around 70GB for months and then one night someone tried to copy a 50GB dump file to the LUN. What is the impact of this to say a Windows VM that is using the LUN for storage? Would the drive just disappear from Windows' perspective? And if this happened in real life ( it hasn't I'm just trying to understand Netapp storage better - phew) how would one go about recovering from this faux-pas? Just go in and resize the LUN and re-boot the VM?
