This is not a problem if the client is mounting the iscsi partition read only. danny Thanks everyone who responded on and off list to me. DAve -- Three years now I've asked Google why they don't have a logo change for Memorial Day. Why do they choose to do logos for other non-international holidays, but nothing for Veterans? Maybe they forgot who made that choice possible.
