View Full Version : [ubuntu] Reinstall Hardy

May 18th, 2008, 11:09 PM
I recently moved my home partition using this (http://www.psychocats.net/ubuntu/separatehome) set of directions from Psychocats. Everything seemed to go pretty well, but after rebooting it wasn't able to find the Home partition. Running the LiveCD, I was able to determine that all the files did transfer to the new partition, so I thought the easiest way to solve the problem is to reinstall Hardy on the original partition. I was going to do this anyway (and add OpenSUSE) so I'm not losing any time...

Any thoughts?

Its easy to install, but you don't learn anything.

Check your /etc/fstab file against the one at the psychocats, making sure that you amend the location of your new /home to your partition - they use hda7 which may well be different to yours.

If you can get it working you will be able to share the /home partition between the two distributions.

kwacka inspired me to do this the right way. here's the problem:

the data on the original partition (sda1) now takes all the storage space given to it. the psychocats manual suggests i can delete the /home_backup from the partition to free up some room, but after running the command (sudo rm -rf /home_backup) nothing happens...there is no output from terminal, just a new command line/prompt.

Also, I'm not sure what is going on with fstab. I saved this line

/dev/sda3 /home ext3 nodev,nosuid 0 2 as per the manual but this is how fstab reads after saving the change and rebooting


unionfs / unionfs rw 0 0
tmpfs /tmp tmpfs nosuid,nodev 0 0
/dev/sda5 swap swap defaults 0 0

...the added line is gone.

I suspect you did but did you edit as root? Always make a backup copy first though.

I guess I didn't make changes to it as root...I thought I did. Opened the file
sudo gedit /etc/fstab added the line, saved the changes and rebooted. How should I have edited it?

unionfs / unionfs rw 0 0
tmpfs /tmp tmpfs nosuid,nodev 0 0
/dev/sda5 swap swap defaults 0 0

This looks like the fstab from the LiveCD. You need edit the fstab from your Ubuntu partition.

sudo mkdir /ubuntu
sudo mount -t ext3 /dev/sda1 /ubuntu
gksudo gedit /ubuntu/etc/fstab

Thanks, meierfra. I ran the three commands...and fstab was completely blank

Did you get any error message after "sudo mount -t ext3 /dev/sda1 /ubuntu"?

Maybe /dev/sda1 is not your root partition? Post the output of

sudo fdisk -l
(l is a lower case L)

I didn't get any errors after running commands; I was very surprised I had this problem because everything seemed to go smoothly.

Here is the fdisk output

Are you sure that sda1 is the root partition? Could it be sda3?

You might try

sudo mkdir /ubuntu
sudo mount -t ext3 /dev/sda1 /ubuntu
gksudo gedit /ubuntu/etc/fstab

again. Maybe you just had a typo.

Or try with sda3 in place of sda1.

You could also try to find "fstab" manually: Go to Places->Computer and double click the icon for the ubuntu root partition. (Actually you might also have an icon for the Ubuntu partition on your desktop) Browse to /etc and see whether you can find "fstab"

I am fairly certain /dev/sda1 is the root directory because it was the partition that originally held /home. I went to Places > Computer and opened /etc/fstab and it was indeed blank.

I also entered "sudo mount -t ext3 /dev/sda1 /ubuntu" then "mount" and got the following information. I don't know what it means or if it is helpful.
