Does anyone have a magic formula for getting a dump from a hard disk onto a multi-volume OD backup? I can't get it to work. Following is a brief description of what I've tried. Having invested the time to set up our NeXTcube as a server on a PC-NFS network, I decided to back it up. After chasing down the scattered hints on backing up, I tried to back up the 360 Mb hard drive onto two (initialized) ODs. I'm using: dump 0uoOf 239 /dev/od0a Why specify the device with the "f" flag when it should default to the optical disk when using the "o" flag? It didn't. It still tried to use the (nonexistent) tape drive. This way, it wrote until it got a "write error". I interpreted this to mean the end of medium (it came at a reasonable point), then attempted to switch disks by firing up a second shell, then: umount /dev/od0a disk -e /dev/rod0a Continuing the directions from the on-line NeXT "Maintainance" chapter, I tried: mount /dev/od0a /backup with no success. I couldn't convince the backup to continue. It kept claiming a SIGFPE and reasking for the disk. Help? Suggestions? -Dean -- Dean Pentcheff (pentch@u.washington.edu) Department of Integrative Biology, University of California, Berkeley CA 94720 Presently at: Friday Harbor Labs, 620 University Rd., Friday Harbor, WA 98250
