If the controller does the right thing, you could probably just camcontrol rescan 0. If not, a reboot would be necessary. In either case, you then would update your fdisk partition, then disklabel, then growfs. This is documented on the growfs man page. > Have you ever tried increasing the size of a live filesystem using OCE? For growfs, you need to at least unmount the fs. -Nate To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
