We've outgrown our /usr partition and I need to expand the disk. Due to disk needs, I plan to replace the 1GB drive with a 2GB, partition it about the same (except for a larger partition for /usr), copy all the file systems with dump | restore, and then take the old 1GB disk and use it in my Sun which is in dire need of space also. I'm a bit weak on low-level maintenance functions in Unix, although I did add disks to SunOS before. I have a 4.4BSD manual, but some of the commands (format, scsiformat) don't appear to be in FreeBSD. I'd like it if someone could guide me toward the right commands to do what I need to do (and I'll figure it out from there). Here are the tasks I see: 1. Read the old partition size info, so I know how to partition the new disk (fdisk doesn't do it; just shows one big partition). 2. Partition the new disk (including sub-partitions?). 3. Do I need to format the partitions, or is that what newfs does? 4. Do I even need to newfs, if I'm doing dump | restore? And in a related question, I hooked up an HP DAT drive (Surestore 6000) and I want to make dumps. A few questions: 1. I seem to automagically have a /dev/rst0 device. Is that the right one for this tape drive? I have no other st devices in /dev. 2. How do I format the DAT tapes? (No "format" command on my system.) 3. If I dump "/", will it dump my other mounted partitions, or do I have to dump them separately? 4. If separately, how do I dump multiple partitions onto one tape? (I have 2GB tapes; no problem with space.) Thanks in advance for any pointers you can give. Email cc will help. Regards, John -- John R. Haggis haggis@cesium.com
