You might also want to take a look at http://www.nslu2-linux.org/wiki/HowTo/3orMoreEXT3DrivesWithAUSBHub as I have had perfect results with that method.

1. Note that any user shares you create will be created on the disk in port 2 (the flash disk) as you can't specify where to put them! So maybe you won't want to create them...

1. Now we have to tell the slug to mount the drive on startup after running rc.bootbin but before starting Samba. We'll do this with a diversion script called /unslung/rc.samba. From the shell, type "cat > /unslung/rc.samba" and paste in the following text:

Due to the odd behavior of rc.bootbin as discussed in R63DiskBehaviour, it is not advisable to use two natively-formatted disks in R63 or Unslung6!

How to set up a workable two-disk configuration in R63/Unslung6

Due to the odd behavior of rc.bootbin as discussed in R63DiskBehaviour?, it is not advisable to use two natively-formatted disks in R63 or Unslung6!

The following setup does work, however!

We will use a USB flash disk in port 2 (/dev/sda) and a USB hard disk in port 1 (/dev/sdb). This maximizes flexibility and compatibility.

1. Start with a fresh NSLU2!
2. Install Unslung 6.x. Do not configure any shares or users yet!
3. Insert the flash drive in port 2 and format it through the Web interface. It will remain here forever!
4. Reboot
5. Get a shell and unsling to the flash with "unsling disk2"
6. Reboot
7. Use another PC to configure your USB hard disk (or second flash device) with a single large partition, if it isn't that way already. You will not be using the GUI on the NSLU2 to partition it!
8. Plut the second USB drive into port 1 of the NSLU2
9. Get a shell and format it as ext3 with "mkfs.ext3 /dev/sdb1"
10. We will mount it under the flash disk at /share/flash/data/sdb. You must create this directory now from the shell with "mkdir /share/flash/data/sdb".
11. Now we have to tell the slug to mount the drive on startup after running rc.bootbin but before starting Samba. We'll do this with a diversion script? called /unslung/rc.samba. From the shell, type "cat > /unslung/rc.samba" and paste in the following text:

(:table border=0 width=100% bgcolor=#eeeeff:) (:cell:)

 
#! /bin/sh
# Diversion script: to mount a formatted drive under /share/flash/data
#
mount /dev/sdb1 /share/flash/data/sdb

return 1

(:tableend:)

1. Now reboot. When it comes up, your df output should look like this:

(:table border=0 width=100% bgcolor=#eeeeff:) (:cell:)

 
# df
Filesystem 1k-blocks Used Available Use% Mounted on
rootfs 723320 34748 681224 5% /
/dev/sda1 6528 6328 200 97% /initrd
/dev/sda1 723320 34748 681224 5% /

/dev/sdb1 480719056 5497276 450802580 1% /share/flash/data/sdb

(:tableend:)

1. Now you can create users and shares. Specify "Disk 2" for shares and specify "/sdb/whatever" when creating a share. For example, a music share would be on "Disk 2" and would specify the "/sdb/music/" folder in the GUI. Don't worry - it'll actually reside on the disk you mounted on sdb.
2. Note that any user shares you create will be created on the disk in port 2 (the flash disk) as you can't specify where to put them! So maybe you won't want to create them...
