Since 80 GB of disk space is a lot, you could also use the second disk
as a temp area, while joining /var and /usr of the first disk into a
new /var. This could easily be done with:
1) Boot in single user mode.
2) Create & newfs a huge /usr on your second disk, that can
accomodate both your current /var and /usr partitions
(i.e., da1s1a).
3) Mount your new /usr partition under /mnt from da1s1a.
4) Use dump & restore to move things from your current /usr
into /mnt. I't probably a good idea to copy /var into
/mnt/var instead of deeper.
5) Move away (do not delete, yet) your exiting /var, and create a
symlink /var -> /usr/var.
6) Update your /etc/fstab to make sure the old /var and /usr
partitions are not used.
7) Boot your system and check for any problems.
If all seems fine, you can remove the old /var and /usr partitions
from da0, your first disk. Then, create a single partition that will
eventually hold your /var partition which spans the space previously
occupied by the original /var and /usr partitions, and move to the
second part of the process:
1) Boot single user again.
2) Mount da1s1e which now has the space of your old /var and /usr
under /mnt.
3) Use dump & restore to move stuff from /usr/var to /mnt.
4) Remove the symlink of /var -> /usr/var and create a directory
/var (owned by root:wheel with permissions 0755).
5) Unmount /mnt and remount it at /var.
6) Exit single user mode.
If all works fine, you can delete /usr/var.
