Re-assign partitions

rvijay17 · 01-10-2009, 05:52 AM

Hi,

I installed Ubuntu a week back and while doing the same, I had to make a different partition for /home. But by mistake, I created a new partition for /usr and realised it only after the whole installation was done.

Is there a way to swap /usr and /home partitions?

Regards,
Vijay.

Please post the contents of /etc/fstab. and also open a terminal and run "fdisk -l" (run as root--"ell", not "one"). Post this also.

The problem with swapping them, is that you already have configuration info in the partition mounted at /home.

The instructions below work for moving /home to a formatted ext3 partition from / after moving /usr to /. Maybe instructions for moving /usr are in here also if one looks deep.

Code:

As root or sudo, or single user mode:
1: #mkdir /mnt/newhome
2: #fdisk -l   (to find device name of partition)
3: #mount -t ext3 /dev/???? /mnt/newhome (replace check marks in /dev/xxxx as per output of fdisk -l command)
4: #cd /home
5: #cp -ax * /mnt/newhome
6: #cd /
7: #rm -fr /home
8: #umount /mnt/newhome
9: #mv /mnt/newhome /home
10: #vim /etc/fstab (edit /etc/fstab with favorite editor if not vim, and add line below with proper /dev/xxxx)
11: /dev/???? /home ext3 defaults 1 2
12: re-boot
