Yes, that's a valid reason. It wouldn't be with vinum, because > you could then just create individual volumes. So each vinum volume is a logical disk, and you still get the performance boost from striping, but you get the other vinum features as well, such as raid-5 and the ability to add additional space to a volume on the fly? In my case, I'd just create volumes that are 2 GB or less. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
