Once my FreeNAS server was up and running, I needed to get my existing data on to it. One possibility is copying over the LAN, but since most of my data is held on ext2 Linux had drives, it made sens to me to mount these drives in the FreeNAS server, and copy using the command line.
Here is an example on how to achieve it. I have chosen to copy the contents of a 400GB IDE HD which holds my MP3 music collection into the FreeNAS file store.
Firstly the 400GB IDE drive needs to be connected into the system. This is straightforward - just connect an IDE ribbon cable from the motherboard to the disk, and connect up a MOLEX power connector from the power supply. Once that's done, boot up the machine.
Using a remote browser pointing to the FreeNAS server, I pointed it to 192.168.0.9 which is the IP address allocated to the server by the DHCP service running on my hub. Then click on Shell in the GUI. This loads up the root shell in a dialog box. Very handy!
Firstly, I needed to determine which partition (or slice in FreeBSD parlance) my music collection resides on the disk. After a little playing around using fdisk I discovered it's /dev/ada0s1
