First off I want to thank 'dynek' for his tutorial, and all the members that are reading this post.

Using: WNDR3800 running (at the time of the install) 10-12-12-r20119-testing since then moved back to 07-20-12-r19519.

My USB drive initial configuration:
MBR partitioned:
1st (sda1) ~450GB of data (ext 3)
2nd (sda2) 25GB of data (ext 3)
3rd (sda3) ~450GB of data (NTFS)
4th (sda4) 2GB partition for OpenWRT (named the partition OptWare)

Followed all instructions and kept changing 'sda_part1' with OptWare as I have created a mount point /tmp/mnt/OptWare (I have also created a mount point for the other three partitions but they weren't involved in the install).

I had no problems going through all the instructions and the places where packages have been switched for newer ones went without a hitch.

My problem started once the last reboot happened as since then the only partition that is automounting is sda1 under 'sda_part1'. What is confounding me is that I have changed all the 'sda_part1' with 'OptWare' and yet after reboot for some reason it picks sda1 (not sda4) and mounts it as 'sda_part1'.

Since then I have hoped to start over so I reflashed my router with an 'older' FW (07-20-12-r19519), and asked for all the settings to be moved back to default.

Even after all that I still have only sda1 being automounted under 'sda_part1'.

Could anyone help me with setting my router so all the settings are back to normal and 'sda_part1' does not get mounted any more? What file should I look into/change to make this happen?

Also, what I find strange is that when I tried to use a Web GUI to run following commands 'mount -t ext 3 -o rw /dev/sda1 /mnt/optware' (since then I have re-formated my HD and put optware as sda1) nothing happens but when I run that command within the SSH session it works fine.

Any help is greatly appreciated.

Thank you,

Stevan

Edit - I built a second router and followed my own instructions. The original posting has been revised in-place for clarity.

I'm completely new to DD-WRT and had a difficult time reading hundreds of posts in order to figure out how to install Optware onto a WNDR3700v1. My goal was to create an http server for the Roksbox movie player, using an USB attached 500 GB hard drive. I also wanted to install a DLNA server. Fellow newbies, I hope this summary helps you out.

Background:
SSH is used to remote login into the router. I used putty.exe to ssh into the router. Be sure to turn on "SSHd" under the router config "Services->SSHd->enable". Use puttygen.exe to create a public passkey; paste into the router SSHd "Authorized Keys." In putty.exe, link to the private key under "Putty->connection->SSH->Auth".

DD-WRT Versions
I found, with great pain and suffering, that DD-WRT doesn't flash on all WNDR3700 V1 routers. It kept bricking the router. I ended having to flash build 17201, which ultimately wasn't compatible with minidlna (got segmentation faults). I finally found that I could flash from build 17201 to 19342 without bricking. This write-up is for a WNDR3700V1 with DD-WRT std - build 19342.

Format the hard drive:
http://www.dd-wrt.com/wiki/index.php/How_to_-_Format_and_Partition_External_Storage_Device

The write-up says to create a 512 MB Optware partition, but minidlna and lighttpd only take about 20 MB.

Setup USB
In router config page, "Services, USB." Enable all except USB printer. Disc mount point "/mnt"

Reboot

Install Optware:
Follow instructions on page 1 of this post, except using the update links, below:

wget http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/libc_0.9.33.2-1_ar71xx.ipk
wget http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/opkg_618-3_ar71xx.ipk
ipkg install libc_0.9.33.2-1_ar71xx.ipk opkg_618-3_ar71xx.ipk

After the "opkg update" step, re-install libc using opkg (ipkg failed for me and caused great pain and suffering later)
cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/libc_0.9.33.2-1_ar71xx.ipk
opkg install libc_0.9.33.2-1_ar71xx.ipk

Install busybox (needed to enable swap partition)
opkg install busybox

Install lighttpd
opkg install lighttpd

Modify lighhtpd config
vi /opt/etc/lighttpd/lighttpd.conf

Change the following lines to (remove #, if necessary):

server.document-root = "/mnt/"
server.port = 81
server.dir-listing = "enable"

Also change the following:
vi /opt/etc/init.d/lighttpd

Delete everything and replace with:

#!/bin/sh

#source /mnt/root/.profile

BIN=lighttpd
LOG_D=/var/log/$BIN
RUN_D=/var/run
PID_F=$RUN_D/$BIN.pid

COND=$1
[ $# -eq 0 ] && COND="start"

case $COND in
stop)
killall lighttpd
killall php-cgi
;;
start)
mkdir -p $LOG_D
mkdir -p $RUN_D
$BIN -f /opt/etc/lighttpd/lighttpd.conf -m /opt/usr/lib/lighttpd
;;
*)
exit 1
esac

Set it as a service
chmod a+x /opt/etc/init.d/lighttpd
ln -s /opt/etc/init.d/lighttpd /opt/etc/init.d/S80lighttpd

Mount data partition, utilize swap partition, and start lighhtpd using the "Administartion->Commands-> Save Startup":

#!/bin/sh

sleep 5
/bin/busybox swapon /dev/sda2

sleep 2
if [ -f /mnt/sda_part1/optware.enable ]; then
mount -o bind /mnt/sda_part1/etc /etc
mount -o bind /mnt/sda_part1/root /tmp/root
mount -o bind /mnt/sda_part1/opt /opt
else
exit
fi

if [ -d /opt/usr ]; then
export LD_LIBRARY_PATH='/opt/lib:/opt/usr/lib:/lib:/usr/lib'
export PATH='/opt/bin:/opt/usr/bin:/opt/sbin:/opt/usr/sbin:/bin:/sbin:/usr/sbin:/usr/bin'
else
exit
fi

sleep 2
mount -t ext3 /dev/sda3 /mnt
/opt/etc/init.d/lighttpd

sleep 2
minidlna -f /opt/etc/config/minidlna.conf

Install minidlna
opkg install minidlna

Also change the following:
rm /opt/etc/config/minidlna

vi /opt/etc/config/minidlna.conf and add the following:

#port for HTTP (descriptions, SOAP, media transfer) traffic
port=8200

# network interface to bind to (this is the only interface that will serve files)
network_interface=br0

# set this to the directory you want scanned.

Enable Samba (allows you to read/write to drive from Win 7):

"Services->NAS->Samba->enable" (leave everything else blank of disabled

add path to "/tmp/mnt;" name it "USB Drive;" check "Public" and "Read/Write"

Reboot

In Win 7, computer, connect network drive, browse to router IP.

Lessons Learned
My USB attached hard drive didn't show up as a disc, but instead as /dev/sda1 (Optware ext3 partition), /dev/sda2 (linuxswap partition), and /dev/sda3 (Data ext3 partition)

Edit
I wanted to create a script that will generate an html file linking all the movie poster art to the movie itself. The script is below:

#!/bin/bash

rm sorted_names
rm movies.html
find | sort -n > sorted_names

FILENAME=sorted_names

while read LINE
do
ext=$(echo $LINE | tail -c -4)

if [[ "$ext" == "m4v" ]]
then
echo "<a href=\"$LINE\" >" >> movies.html
echo "<img src=\"${LINE%????}.jpg\"width=\"360\" height=\"510\" />" >> movies.html
fi

done < $FILENAME
rm sorted_names

Does anyone know what the reason a Bus Error would appear when trying to start a service (Asterisk) in my case?
This has been working perfectly for over 6 months, had power drop on the router, after it rebooted, I'm getting this error.

I've verified space is not an issue I have 3.1GB's free on a 4 Gig USB. I'm reboot and power reset the router, still not luck in getting the service back started. Help please.

Ok, came back to this after some reading and fiddling.

Basically my problem was /mnt/sda_part2 was getting 'deleted' after a reboot.

I had to manually mkdir -p /mnt/sda_part2 everytime.

Everything else was working great using the OPs guide, and some of the above. Many many thanks to you all!

I solved this by adding a file called 'mountsda2.enable' in the same place as 'optware.enable' and added this to the startup command:

#!/bin/sh

sleep 5
/bin/busybox swapon /dev/sda2

sleep 2
if [ -f /mnt/sda_part1/optware.enable ]; then
mount -o bind /mnt/sda_part1/etc /etc
mount -o bind /mnt/sda_part1/root /tmp/root
mount -o bind /mnt/sda_part1/opt /opt
else
exit
fi

sleep 2
if [ -f /mnt/sda_part1/mountsda2.enable ]; then
mkdir -p /mnt/sda_part2
mount -t ext3 /dev/sda3 /mnt/sda_part2
else
exit
fi

if [ -d /opt/usr ]; then
export LD_LIBRARY_PATH='/opt/lib:/opt/usr/lib:/lib:/usr/lib'
export PATH='/opt/bin:/opt/usr/bin:/opt/sbin:/opt/usr/sbin:/bin:/sbin:/usr/sbin:/usr/bin'
else
exit
fi

This probably isnt the best way to do it but it works and my 230gb data partition is mounted after a reboot

Now could someone tell me how I can tell if the swap partition is active and being used?

using these guides i got my WDR3600 with optware+lighttpd+php but i cant finish mysql instalation, can someone help me?
i installed it by opkg command, it goes all right but i cant start it, tried a lot of differente combinations and configs and got a lot of diferent errors.

any hero to save my day?

For a long time everything works fine on my router tp-link 1043 with dd-wrt + 500Gb HD + Transmission.

Suddenly transmission start an error, when I check I found following situation:

rootfs on / type rootfs (rw)
/dev/root on / type squashfs (ro,relatime)
proc on /proc type proc (rw,relatime)
sysfs on /sys type sysfs (rw,relatime)
debugfs on /sys/kernel/debug type debugfs (rw,relatime)
ramfs on /tmp type ramfs (rw,relatime)
none on /dev type tmpfs (rw,relatime,size=512k)
devpts on /dev/pts type devpts (rw,relatime,mode=600)
devpts on /proc/bus/usb type usbfs (rw,relatime)
/dev/sda1 on /tmp/mnt/sda_part1 type ext2 (ro,relatime)
/dev/sda1 on /etc type ext2 (ro,relatime)
/dev/sda1 on /tmp/root type ext2 (ro,relatime)
/dev/sda1 on /opt type ext2 (ro,relatime)
/dev/sda2 on /tmp/mnt/sda_part2 type fuseblk (rw,relatime,user_id=0,group_id=0,allow_other,blksize=4096)


Devices mounted on /dev/sda1 are RO.
Someone could help-me to found why this is happening.

PS: /tmp/mnt/sda_part1 are mount automatically, configured by GUI from dd-wrt and it works mounting as RW, but when it runs the script to mount the others it turns to RO

These are commands I use mount in the script:
mount -o bind /mnt/sda_part1/etc /etc
mount -o bind /mnt/sda_part1/root /tmp/root
mount -o bind /mnt/sda_part1/opt /opt
ntfs-3g -o rw /dev/sda2 /mnt/sda_part2

How to fix it from dd-wrt?

[axgupta1]

I use private/public key to ssh into my router. After executing the following command, the private/public key login fails to work. The normal password based ssh login continues to work:

mount -o bind /mnt/sda_part1/root /tmp/root

Any workaround?

Thanks...

hi, pls help me.
I installed last dd wrt on tp link wr1043nd.
formated hdd with http://www.dd-wrt.com/wiki/index.php/How_to_-_Format_and_Partition_External_Storage_Device
connect hdd to router on /mnt
try to install optware
and error in step 5 not resolving.
sorry for my bad english

[hgroover]

This is a great list and many thanks for sharing it.

I have a 1TB USB drive (Western Digital Smartbook) that needed some additional startup script options.

Instead of
sleep 5

in the startup script, I needed to have
/sbin/udevtrigger
sleep 15

The udevtrigger is needed for some larger USB drives that take a little time to spin up and initialize. The added sleep time gives time for the udev scripts which automount the drive when detected.

Other than that everything went well.

Hi,

I have wrt160nl ruter.
I currently use 14929 build firmware.
I would like to switch firmware r20453.
My problem is, I didn't mount pen drive and use nvram.
How to use nvram via pen driver.
Currently, I need to install it. (r14929)

wget http://wrt160nl.org/files/wrt160nlmod.sh
chmod +x wrt160nlmod.sh
./wrt160nlmod.sh initiate

Mount (14929)
mount /dev/scsi/host0/bus0/target0/lun0/part1 /mnt/
(r20453)
There is none. /dev/scsi ......
And nvram use via pen drive.


What can I do?
