Well, sort of. But this is where it starts getting scary to answer. The more specific I get, and the less you know, the easier it is for you to blow something away and then it's my fault. Make printouts of your disk layouts and fstab before starting. Anyway, it looks like /dev/wd1s1b and /dev/wd1s1e are adjacent, and the amount currently on /var is minimal, which means you _should_ be able to do what I said earlier, backing up to /usr/var.tar. I'm not sure if freebsd is okay with you taking away swap after dropping into single user mode. I've done that plenty of times with other 'nixs but not freebsd, and I'd hate to see something die while you're in the middle. You may have to reboot to single user in that step before repartitioning with /stand/sysinstall->index->disklabel. That would make it something like: shutdown now cd /var && tar -cvf /usr/var.tar * ls -l /usr/var.tar (confirm it's about 8MB) reboot (at the countdown, hit a key and type "boot -s" at the prompt) mount (confirm only / is mounted) /stand/sysinstall->Index->label->wd1 (remove wd1s1b and wd1s1e and recreate with new sizes, in the same order, making sure to enable newfs for the new /var) mount -a (did it work? you should now have filesystems back online. If so...) cd /var && tar -xpvf /usr/var.tar (did it work? var should be restored.) reboot - you're done You're going to have to be daring and try it or wait for someone else to scream that I've forgotten something important. Hope not. In any case, the less you're comfortable here the more you should want to back things up first. Unwanted clean reinstalls are educational but rarely fun.
