The main point is that I only see this problem with removeable disks and other kind of SCSI-devices, which I usually wire down. Most of my fixed disks are running with vinum. vinum is able to handle if a drive has changed it's ID and/or name. It's an important thing to have something like this if you want to be able to hotplug a drive (or power up later). Sometimes it's getting another name than it would have after reboot! -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
