Very Computer

(1) partition (fdisk) and format (mkfs) the 350M drive;
(2) Mount (mount) it somewhere and then copy (cp -avx) your current
    /usr directory to it, then unmount (umount) it;
(3) Rename (mv) /usr to /oldusr, and make (mkdir) a new, empty
    /usr directory.
(4) Make an fstab (man fstab) entry to mount the drive to /usr
    at boot time;
(5) Reboot, make sure the new filesystem is mounted (df), and then
    make sure everything in /usr still works;
(6) When satisfied, remove (rm -rf) /oldusr with its contents.

Look up the commands in parentheses (man <command>) to understand them
before using them!  This will take some study, but you'll be very glad to
have the experience.

Hope this helps.

1)      mount the ext2 formatted 350 on, say, /mnt
2)      cd /
3)      cp -a /usr/ /mnt
4)      Look in /mnt to see if it looks right.
5)      umount /mnt
6)      modify /etc/fstab to mount the 350 on /usr
7)      mv usr usr-save
8)      mkdir /usr
9)      mount the 350 on /usr
10)     If things seem to work, then rm -rf usr-save

Steps 7), 8), and 9) should be done back-to-back with no other activity
in-between them.  You also might want to be sure that mkdir, mv, and mount
are in /bin and not /usr/bin, and use ldd to check that any libraries mkdir,
mv, and mount need are in /lib and not /usr/lib.

And be sure to check my logic, this carries no guarantee or warranty.
To quote from the chat (for pppd) man pages: "If it breaks, you get to
keep both pieces." ;)  Everyone should have a backup and a good rescue
disk handy.

If you want a "tar thing" ala "Running Linux", it appears to be

cd /usr
tar cf - . | (cd ../mnt; tar xvf -)
cd /

and would replace 3) above.  When I when through this a few weeks ago
it seemed simplier to use cp since all the other steps are necessary
whether using cp or tar.

: I finally have the extra hard drive working with linux, it is a 350 Meg
: HD just used for extra space.  The first drive is a 540 meg drive for
: the rest of the linux system, and "hdb" is a 3.2 Gig drive for
: windows/dos, I have now added the 350 Meg drive as an additional linux,
: but is there a way I can use the new drive for /usr, or just cp the
: entire /usr directory to that drive(I'm out of space on my first drive)?
: How can I do this? Is this that "tar" thing? if so, how do I go about
: doing it?
