Shutdown, yes, but capitol K, i don't remember, it's been awhile but i have another drive now so i can try again.
Thank you though for the response with the advanced settings, i'm going to try that, i'm really interested in why the vmotion isn't working even between datastores with different block sizes. There are plenty of other ways to reclaim it but we may not be upgrading anytime soon and i'd love for vmotion to reclaim disk space in these scenerios.
