I followed the steps you described and with no gr8 success.

I can see the 2nd partition (FAT32) that I mounted to /mnt but it's very slow and gets stuck reading and writing from it.

how could i speed it up ?


well read again the second step > where we were told not to use FAT at all.

try this
Code:
2. Mount your USB storage on /opt. The file system *must* be either ext2 or ext3; do not use FAT, VFAT, or FAT32.2.


Yes well i thank you for taking the time to tell me that, but:
A. what are you trying to say
B. if you have taken the time to read exactly what i wrote you would see that I I have 1 partiton EXT3 and the rest is in fat32 i loaded samba and everything to the EXT3 partition.
I actually could read\write to the FAT32 partition mounted to /mnt !! but it is very slow + it deform my native characters (hebrew).
I am now at the point i have gave up on this, I flashed back to linksys firmware and i will wait for the brave one that will make this part of the Mega release. built in.

Thanks to everyone

I have had problems using the FAT32 file system with the dd-wrt USB2.0 implementations, especially when writing large files to the FAT32 partition. It could just be that I was using an old flash stick that was having write errors (doubtful, but possible) that FAT32 couldn't handle but ext3 could (ext2 and ext3 are much more resistant to bad media blocks than FAT32).

Don't know why your FAT32 was so slow; read/write speeds to/from FAT32 were about the same as ext3 for me (directly on the router, not via a client over samba), at least while my FAT32 file system was working. I suppose you could try sharing your ext file system and comparing speeds; the problem could be completely unrelated to the file system type.

As I've said in other threads, I'm a Unix/Linux user/programmer/hacker, not a Windows person, so I tend to avoid anything invented by Microsoft (including FAT32) unless I have no choice (like running XP on my wife's PC; too bad Quicken crashes on wine).

I have try this :
1. flash using dd-wrt.v24-101037_NEWD_mini_usb
2. actived usb support almost all except support 2.0
3. using my ipod nano , create partition ext3 1 GB and format using mkfs.ext3 at different computer.
4. the router found /dev/scsi......part1 , i mount to /jffs/opt and mount -o bind /jffs/opt /opt
5. run this step wget http://www.wlan-sat.com/boleo/optware/optware-install-ddwrt.sh -O - | tr -d '\r' > /tmp/optware-install.sh
sh /tmp/optware-install.sh
all working fine
6. install package openvpn using ipkg install openvpn
and openvpn running well
7. install samba2 using ipkg install samba2
but it have problem after finish download ,
when i try tar xvf samba......ipk the router stuck

I try to downlod this samba2.tar.gz , uncompressed to /opt but when try to smbd start it show "bus error"

I'm not sure where the problem is , from the usb disc ? or from firmware ?
it always stuck when uncompressed large files
if i pull out the usb flash , the router respond.

Okay, what model router do you have? I have an Asus WL-520GU.

For my router, I disabled USB 1.1 support (both UHCI and OHCI) and enabled USB 2.0 support (USB 2.0 is working on the 520GU as of 10137; there was a later patch -- 10328 -- for the Asus 500GP/V2). Also enabled USB storage support and ext2/ext3 file system support. I don't know what will happen if you have USB 1.1 and USB 2.0 drivers enabled at the same time; I think only one should be active, since USB 2.0 is compatible with 1.1 devices.

I mounted my USB device on /mnt, not /jffs. If you have jffs2 enabled, I have no idea what happens if you attempt to mount another file system over /jffs, so don't do that for now.

Make sure you clear out the /opt directory structure before attempting to install my samba2.tar.gz package. There are some conflicts from the optware library package with my startup script.

The problem is that there simply isn't enough room to store all the samba stuff in a dd-wrt build, even one targeted for an 8MB (or even 16MB, if there is such a thing) router. The samba2 install package is > 7MB compressed. The optware uclibc libraries are > 10MB compressed. Won't fit. Period.

can i use a USB stick to extend the flash space?

Not the way you want. You can't extend the flash space of the dd-wrt binary download. You can only extend the total storage on your system after dd-wrt boots by mounting the file system on your usb stick. That's why samba is installed as a separate package and isn't part of the dd-wrt base install.

Has anyone tried supporting multiple external hard drives with a USB hub? It seems it should technically work, but I was wondering if anyone managed to get it working in practice.
