Move home folder to second drive

Question

I have 2 HDD drives in my computer. At the moment second drive is mounted as /media/storage.

How can I move my user data from /home to /media/storage/home?

Can I just move the data over there and then simply symlink it back?

Answer 1

If you want to just move your home directory i.e /home/your-username then simply copy your home directory to other partition and then use System->Administration->Users & Groups to open user settings dialog. Click on the keys icon to authenticate your self

After that select the user that you want to change and click properties, go to advanced tab

change the home directory to new directory i.e the directory that you copied to other partition.

Moving HOME from command line

To avoid side effects while working in a graphical environment we should perform all actions to move HOME from a terminal with Ctrl+Alt+F1.

Temporarily mount the new partition:

sudo mkdir /mnt/tmp
sudo mount /dev/sdb1/ /mnt/tmp

^{assuming /sdb1 is the new partition for HOME}

Copy HOME to the new location:

sudo rsync -avx /home/ /mnt/tmp

We then may mount the new partition as HOME with sudo mount /dev/dsb1 /home to make sure all data are present. Easiest is to delete the old /home at this point (you could do this later but then you will have to boot a live system to see the old home):

sudo umount /home  #unmount the new home first!
rm -rf /home/*  #deletes the old home

Make HOME permanent

We need to know the UUID of the new partition for the fstab entry seen from:

sudo blkid

Note or copy/paste the correct UUID to edit your fstab with

sudo nano /etc/fstab   #or any other editor

and add the following line at the end:

UUID=<noted number from above>    /home    ext4    defaults   0  2

^{Take care to choose the appropriate filesystem here, e.g. ext3 if ext3 formatted}

Reboot

After a reboot your /home resides on the new drive having plenty of space.

Indeed. it is a great way to easily change the home directory location of a specific user. While reading the question, I was understanding that this would have been for the /home directory globally. In this case, you could create the partition on the other device, manually move all files there and then change the device for the mount point in /etc/fstab file itself

Answer 4

ok, the only way I found this would work is to create another user, give it admin authority, logoff the main id, logon with the new id and then use usermod command.
