Summary - Moving mail to new disk

The original problem was that the / partition, which was only about 14
Megabytes, had the mail files on it and frequently filled up, causing the
computer to have a problem, as you can well imagine.
I installed a new hard drive and was able to do that because of this group.
I then moved the print files, but not the print program to the new disk
and then set up some soft links from the old directories to the new
directories.

Procedure:
1. Change to single-user mode by logging in as su. This stopped anyone
from using the
mail program.

2. Copy the files from /var/spool/mail to /new1/mail
cp -rp /var/spool/mail /new1 /* this is a recursive-preserve copy,
which
chown username filename * preserved everything except
ownership. I
* used chown on each file, making everything
/* identical to the original directories.
cp -rp /var/spool/mqueue /new1
chown username filename

3. Remove the original files
cd /var/spool
rm -rf mqueue
rm -rf mail

4. Create soft links.
ln -s /var/spool/mqueue /new1/mqueue
ln -s /var/spool/mail /new1/mail

5. Then I rebooted
shutdown -r now

6. Checked out the mail, directories and file systems. The / file system
was down
to 55% full and is no longer affected by the buildup of mail.

All's well that ends well!

Thanks to all again.
