Due to disk needs, I plan to I'd recommend setting up 2.2.1-Release on the new disk from scratch and migrating the local configuration and datafiles. While this will be more work than a simple dump/restore of all filesystems, it will certainly be worth it to get the new features that 2.1.x doesn't have. > 1.

You only get one big partition from fdisk since it reports the physical layer of the disk. FreeBSD takes a big slice from the drive (what is called a primary partition for the DOS scheme) and divides it into several filesystems (much like a secondary DOS partition that can contain more than one DOS drive). > 2.

I have no other st devices in /dev. This device is sort of an alias to the real scsi-id. > 2. How do I format the DAT tapes? (No "format" command on my > system.) You don't. > 3.

Use the /dev/nrst0 so the tape driver doesn't rewind the tape after dump closes the device. Greetings, Ripley -- H. Eckert, 10777 Berlin, Germany ISO 8859-1: Ä=Ae, Ö=Oe, Ü=Ue, ä=ae, ö=oe, ü=ue, ß=sz.
