On the 140gb hard drive I had the first 40Gb setup for linux. Never
formatted the latter. So I had used Yast to format it and assigned /
home to it thinking it would expand home.

How do I recover the original files and directories lost, without
further screwing up things?

First step is to ensure that all users are logged off, log in as root,
and then to switch to run-level 1 using "init 1". This ensures that
there should be no other users able to log in, and all the files in use
by any other user should be closed.

The next few steps are based upon /home _not_ being on its own
partition, which is something I wouldn't expect with 10.1+ and more than
10GB of free drive space.

Step two, use the "umount /home" command to unmount /home.

Step three, rename /home to something like /old.home and then create a
new /home. The command "mv /home /old.home ; mkdir -p /home" will do
that /mnt.

Step four, use "mount /home" to re-mount the partition /home.

Step five, go to step seven below.

==========

Now, these are for when /home is on a different partition to /

Step two, create the mount point /old.home as a temporary mount point
for the old /home partition using "mkdir -p /old.home"

Step three, use "fdisk -l" to get a list of the partitions, and "df" to
get a list of mounted partitions.

Step four, compare the outputs from fdisk and df to find any partitions
with a type "83" that aren't mounted.

Repeat the next two steps for each partition that isn't mounted but is a
Linux partition (type 83):

Step five, mount the partition on /old.home and then use "ls /old.home"
to find out if it contains the old /home.

Step six, if the partition _isn't_ the old /home, use "umount /old.home"
to unmount the partition, and repeat step five with the next unmounted
partition.

==========

Step seven, now you can go back to either run-level 3 (text console) or
run-level 5 (GUI) by using either "init 3" or "init 5"

Step eight, copy the files from /old.home into /home. You may need to
watch out for files that have been created in the new /home that also
exist in /old.home, e.g. mailbox files.

One thing to note is that if the old home wasn't a separate partition,
/old.home will contain any files and directories that you didn't move
before the reboot.

However, if you had to mount the old home, on the next reboot that
partition won't be re-mounted and so /old.home will be empty. Any files
or directories that you didn't move before the reboot are still there,
you just need to mount the partition to get at them.

Well, it didn't quite work.

here is my df and fdisk output. I forgot how to use tee to capture my
whole process so I just directed the output to a file.

here is what my directory properties look like at root
drwxr-xr-x 2 root root 4096 Mar 31 07:08 old.home

but I could not mount old.home

error message
comlnx:/ # mount /old.home
mount: can't find /old.home in /etc/fstab or /etc/mtab
comlnx:/ #

so please suggest what I'm doing incorrectly.

Thanks
