I'm not sure if I understand this question completely. A file system
is a file system: you can't spread it across two file systems. Let's
consider what you might want to do:
1. Move /var to your new disk. That's straightforward enough.
Modify your /etc/fstab to contain something like
/dev/sd1e /var ufs rw 2 2
This assumes that your new disk is sd1, and that you've put the
space on partition e. If you currently have /var mounted as a
separate file system, modify the existing entry.
Before you mount the disk as /var, you'll need to move the current
/var stuff. First, mount the disk on /mnt, a general-purpose
temporary mount point that you should have on your system:
# mount /dev/sd1e /mnt
Then copy the data across:
# cp -pR /var /mnt
Then *rename* /var, create a new /var, and mount it:
# mv /var /VAR
# mkdir /var
# mount /var
The reason for renaming /var to /VAR is that you won't be able to
delete the old files after you've mounted a new file system on top
of it. On the other hand, it's a good idea to keep the old
contents around for a while until you're sure that you don't need
them any more. This way, when you're sure that everything is OK,
you just need to enter
# rm -rf /VAR
2. You want to split /var between two file systems. For example, you
may want to put /var/spool on the new disk, and leave all the
other files where they were. In this case, you repeat (1) above
substituting /var/spool for /var. If your current /var is a
symlink, use the real directory name for the mount point.
I hope this answers your question. If not, please let me know.
