You don't say whether you're using vinum or gvinum. I've never seen this problem before, but if you're getting incorrect subdisk sizes, try specifying them explicitly: sd length 35840952s drive ibma=20 I wonder whether the problem is related to specifying the size as 0m instead of 0. It shouldn't be. Greg -- When replying to this message, please copy the original recipients. If you don't, I may ignore the reply or reply to the original recipients.
