What steps would be necessary to get a USB flash drive working on the DNS-343?

I have tried following directions for the DNS-323, however they are different enough to not work. When I try to insmod usb-storage.ko, I get "invalid model format".

I don't know what to do next. I've looked for info on compiling a version compatible with the DNS-343, however - i've had no luck so far.

Very interested in the same, mostly because I'd love to put my USB HDD on behind the DNS-343.

robinson · 2009-06-22 00:10:08

Indeed.

My primary reason is to get ffp runing on a USB key, so my HDD's don't keep spinning...

Well, I found out that the kernel version (on 1.03b70) is 2.6.22.7, and the usb-storage.ko has been compiled for a different (edit: earlier) kernel version, hence the error.

grr. now i have to recompile it. here goes gcc, et. al on the NAS...

tada!! I have my USB drive mounted!

I'm working on writing up a tutorial... this was a pain to figure out, mostly because there are "special" versions of everything on the 343. Generic errors suck!

edit 1:
I'll have the tutorials up as soon as I figure out how to get ffp running off of the USB drive as well.

edit2:
Update 1: So.. these things are as sensitive as hell to what KIND of USB flash drive you use. It might work when you unplug/plug it in, but when you BOOT with it in... it doesn't work. Fortunately, I found another drive that worked when you boot.

note: if you plug the incompatible UBS key into a USB hub.... it worked on boot. weird!

Steps to get a USB drive working on the DNS-343. I had firmware 1.03b70 installed.

1) You have to install the kernel modules.
- insmod /sys/crfs/driver/usb-storage.ko
- insmod /sys/crfs/driver/fat.ko
- insmod /sys/crfs/driver/vfat.ko

2) Plug in your USB drive.
- dmesg should show you info about your USB drive. If not - you probably didn't wait long enough.
Initializing USB Mass Storage driver...
scsi4 : SCSI emulation for USB Mass Storage devices
usbcore: registered new interface driver usb-storage
USB Mass Storage support registered.
usb-storage: device found at 2
usb-storage: waiting for device to settle before scanning
scsi 4:0:0:0: Direct-Access SanDisk Cruzer Mini 0.2 PQ: 0 ANSI: 2
sd 4:0:0:0: [sde] 2001888 512-byte hardware sectors (1025 MB)
sd 4:0:0:0: [sde] Write Protect is off
sd 4:0:0:0: [sde] Mode Sense: 03 00 00 00
sd 4:0:0:0: [sde] Assuming drive cache: write through
sd 4:0:0:0: [sde] 2001888 512-byte hardware sectors (1025 MB)
sd 4:0:0:0: [sde] Write Protect is off
sd 4:0:0:0: [sde] Mode Sense: 03 00 00 00
sd 4:0:0:0: [sde] Assuming drive cache: write through
sde: sde1
sd 4:0:0:0: [sde] Attached SCSI removable disk
sd 4:0:0:0: Attached scsi generic sg4 type 0
usb-storage: device scan complete

- fdisk -l should show you where your device is connected (ie. /dev/sde1)

OPTIONAL) You can format the drive to ext2 if you want.
- mke2fs -L USB /dev/sde1
: note: you cannot have the drive mounted when you do this.

3) Mount the drive.
- mkdir /mnt/usb
- mount /dev/sde1 -t vfat /mnt/usb -o noatime
OR mount /dev/sde1 -t ext3 /mnt/usb -o noatime
OR mount /dev/sde1 -t ext2 /mnt/usb -o noatime
- the "-o noatime" prevents linux from writing access times to the files.
- if you want to be able to mount your USB drive so you can access from the network share (from windows)
: mkdir /mnt/HD_a2/USB
: in the mount commands listed above, change "/mnt/usb" -> "/mnt/HD-a2/USB"

4) Check to see if it works:
- ls -l /mnt/usb this should show you the contents of the usb drive.
OR check via windows if you mounted it to a directory on your share.

5) Check to see if it is COMPATIBLE.
: Sometimes a USB drive will be mountable, HOWEVER it will not be compatible with the system.
- Reboot. Make sure to leave the USB drive in the system.
- After you have booted back up, follow steps 1-4 again - BUT make *sure* to not unplug your USB drive.
: If you are able to mount your USB drive *without* un-plugging it, it most likely compatible.
: I had one USB drive that *would not* mount unless i re-plugged it in *every* time I rebooted.

To see more info about your USB drive
- cat /proc/scsi/usb-storage/<hit tab>
- dmesg to see USB connection info
- fdisk -l to see what it's device location is

Awesome! Thanks for putting this together. I'll hopefully have time to hit this in the coming weekend. Thanks again

johnkeye · 2009-07-04 23:37:46

Aww. It does not have support for HFS+ drives at the moment, though the rest went off without a hitch. The drives I've tested show up fine in fdisk, but I'll have to set some time aside to migrate data to reformat a drive, which'll have to wait until I have time. Thanks again for the tutorial
It ought to be put into the wiki.

robinson · 2009-07-13 00:59:47

in order to support HFS+, you'll need HFS+ kernel modules, but yea -- i'm thinking about sticking this on the wiki. DNS-343 wiki info is LACKING.

Hi Robson,

I'm a total newbie on linux and command line ( I mean total!!! ) but I´ve managed to get ffp on my DNS343, have Apache, mysql, and Php running ( wich took me forever to get working! )

I intent to have SABnzb + Sickbeard working off a 32GB USB stick, but I'm stuck on loading the usb-storage.ko ( module invalid )

1) Is there a compatible usb-storage.ko for the 434 or do I have to compile it as you did? How do I go about doing it? ( complete newbie )

2) Know of a good way to get those two packages working on the 343, or am I just wasting time?

3) Where do I download vfat.ko and fat.ko from?

Thanks in advanced
