New page

How to move /usr partition (since I painted myself into a corner by providing myself too little space on the root partition).

Note to self: don't create a 20 GB root partition and a 130 GB home partition.

Note to self: don't let Kali decide what to do, or you'll end up with a 20 GB root partition and a 130 GB home partition.

=Boot Into Live Distro=

This was a good opportunity for me to give Kali's Forensic Mode a whirl. I changed the BIOS menu to make the computer boot from a USB drive, then put the Kali 2 USB drive into the computer and started it up. I picked Forensic mode at the USB menu.

Kali Forensic Mode is a live distribution that does not touch your hard drive at all. While a live distro shouldn't really touch your hard drive anyway, it might use a swap partition, or something like that. The forensic mode is for analyzing hard drives in a forensic environment, so it doesn't touch the disk unless you explicitly give it permission to do so.

=Gparted to Split the Disk=

I used gparted to better split up the 130 GB home partition into three empty partitions of 40, 40, and 50 GB each. Everything was unmounted, I split the one large partition into three smaller partitions, and off we went.

=Move /usr and /root=

Part of the problem was the home partition wasn't even being used, since I was putting most everything into /root. So I literally had painted myself into a corner.

==Instructions for Moving usr/==

===Mount the Partition===

I mounted the too-small partition, and mounted one of the 40 GB partitions.

<pre>
$ cd /mnt
$ mkdir too_small
$ mount /dev/sda1 too_small
$ mkdir usr_partition
$ mount /dev/sda6 usr_partition
</pre>

===Copy the Files===

Now I copied the <code>usr/</code> directory from too_small to usr_partition. (Note: I did not move it, I copied it. You don't want to lose critical usr files if the operation goes wrong!)

<pre>
$ cp -r too_small/usr usr_partition/usr
</pre>

===Move the Old Files===

Keep the old files around, just in case, but move them so they aren't picked up:

<pre>
$ mv hd/usr hd/usr.backup
</pre>

===Map usr/ to New Partition in fstab===

The last step is to put an entry into fstab that will tell the OS to mount /usr at the partition we've created. [http://askubuntu.com/questions/656/how-to-move-usr-to-a-new-partition]

First get the UUID of the disk via:

<pre>
$ ls -l /dev/disk/by-uuid
</pre>

Now edit <code>/etc/fstab</code>:

<pre>
UUID=634c31a5-e27c-4e33-ac67-2e22491a30c2 /usr ext4 defaults 0 2
</pre>
