Hello all,

Router: Linksys E3000
Firmware: DD-WRT v24-sp2 (10/13/10) mega - build 15453M NEWD-2 K2.6 Eko

I had my router setup and working without any issues using a single 160GB drive (formatted as ext3 as per the wiki). This was fine, everything was working no problems. I had read that you can use a USB Hub to connect more than one device to the router, so for Christmas I got a nice 7-port powered USB Hub (D-Link DUB-H7 http://www.dlink.com/products/?pid=149).

I have 3 devices that I would like to get working:
Original 160GB drive (Ext3 formatted, w/ opt installed)
New 2TB drive (NTFS formatted)
HP Photosmart D5400 printer

So this is what I'm running into...
When plug in only the original drive to the usb hub, the router works like normal and mounts the drive.
However, when I attach another device, none of the devices are mounted. I tried looking over the wiki and searching the forum but I'm coming up empty on how to fix this. I ran the 'dmesg' command and found that the router 'sees' all three devices but I don't know what to do from here. I assume I have to manually mount them, however, the devices keep switching 'hosts' on my when the router is rebooted (Sometimes the 160gb will be on host1 other times it will host2, etc.). I'm not quite sure what info you would need to help me, so I'll post what I think might help you help me:

This is my Automount info from the web-GUI BEFORE the usb hub:

Been trying plugging things in at different times and such, but I don't think that is helping any. I tried to do a mount command in the startup script (mind you I really don't know what I'm doing), however, since the "host" for the Optware drive keeps changing when the router reboots, my script never appears to do anything...

Anyone have any input that might help me?

can you post the output of following commands from a telnet/SSH session(preferably):

1) mount
2) df -h
3) lsusb
4) blkid

else you may also try to run these commands from administration/commands/run commands (one by one)

With only my original drive connected to the USB Hub:

twig123,

All of us with more than one storage devices are facing the same problem double/triple mounts on /opt which kills(i.e. makes it inaccessible) optware. In your second case you have triple mounts but /opt is back in there hence optware commands are still running without reboot. When you reboot because of double mount, opt folder is probably double mounted and thus optware does not start hence no optware commands etc work. after reboot,if you issue "umount /opt" using GUI commands, optware commands may start working but optware is still not started. Probably your output was too early before the full boot.

so the issue here is:
1) (probably) automount/dd-wrt are mouting the first partiton to /opt for EVERY DEVICE(this is not a good approach for users with USB HUB or more than one USB ports.
This should get resolved by using "service automount nomount /dev/sdb1" and "mount -n /dev/sdb1 /tmp/d" as mentioned by Frater in some of his posts but the problem is that device names are changing often. The same HDD will become /dev/sda sometimes.
2) the device names keep changing(I don't know why), this probably making automount to confuse even though it uses UUID of the device.
3) In my case even a command like "/opt/bin/ntfs-3g /dev/sdb1 /tmp/d" crashes by router, although it loads the ntfs drivers dynamically.

my recommendation to you would be to setup a kiwi log server on a windows desktop and set the logging to maximum using security->log management but keeping dropped/rejected/accepted to disabled. This will help you see what is happening and when.

also try updating your optware install using:
wget -O ~/prep http://wd.mirmana.com/prep_optware
sh ~/prep

I have also tried almost everything but the biggest probelm is that automount is doing double mount on the /opt mountpoints because "optware the right way" requires automatic drive mount to /opt and this is causing all second USB storage to also be mounted in the /opt which eventually kills optware.

I wish i could find a way to only automatically mount the optware device and use the script way to mount other devices and i could bypass this problem but I am not successful yet. I will post my reply here is i find a solution.

According to this post running HDSamba fixes the multiple drive issue:
http://www.dd-wrt.com/phpBB2/viewtopic.php?p=482578&highlight=hdsamba#482578

I'm not that knowledgeable about DD-WRT yet, so I'm kinda just going with the flow... I've looked through the wiki but didn't have any luck following the directions on installing HDSamba2 (Something about not being able to find JFFS). I searched and found that the JFFS issue may be because I used a "mega" build on my router, so maybe I need to reflash with a "big" build instead (think someone said "mega" doesn't enable/format JFFS correctly...)?

I noticed there is a HDSamba3 (which should include samba 3.5), but everything I've found is how to UPGRADE from HDSamba2 to HDSamba3.

Is there a way to just install HDSamba3 (to my router that already has OTRW running) without first going through the HDSamba2 steps first?

[frater]

Just make sure your /opt is mounted on the lowest partition on the slot with the lowest number.
Leave it there and put subsequent USB devices in the other slots.

Let me know which version of automount you are running and which version of DD-WRT.
Also delete the file /opt/etc/automount before you start swapping disks.

I've asked for feedback after changing automount recently, but I'm not getting any feedback I can work with.

[frater]

Pffff...
Just examined S35automount....
I did some changes (again) and I do hope it's an improvement.
My coding improved since writing it, but it takes time to understand why I'm doing things the way I'm doing it...
I constantly have the urge to completely change it, as it's quite hard to think of every scenario.
Please try this latest version...

I messed some things up when trying to install HDSamba, so I wiped OPT and started fresh again (just a few hours ago).
I'm trying to go about without asking to be spoon-fed what to do line for line... but feel free to feed me if need be.

[frater]

I would first like to know if DD-WRT is the culprit or the automount feature in OTRW.
Give a 'service automount off'
This will make /opt/etc/init.d/S35automount non-executable. This is what we want.

Turn automount on in the webif....
reboot the router

delete /opt/etc/automount

Check your partitions and mounts
Add a device and check them again

run 'bash /opt/etc/init.d/S35automount start'

check partitions and mounts again...

If DD-WRT is the culprit, I could write something that will only mount a certain partition...

[twig123]

I didn't see that you had re-posted when I posted my last message. I'll wipe my OTRW and restart with a fresh install, then post with the results.

Edit: we must both be online I keep just missing your posts while I'm posting

[frater]

If DD-WRT is the culprit, you could turn automount off in the webif and use this code to mount the correct partition

[twig123]

# service automount off

Disabled 'Automatic Drive Mount' (From WebIF)
deleted '/opt/etc/automount' (before reboot, as I don't know how without opt or samba)

# reboot

# mount
rootfs on / type rootfs (rw)
/dev/root on / type squashfs (ro)
none on /dev type devfs (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
ramfs on /tmp type ramfs (rw)
devpts on /dev/pts type devpts (rw)
devpts on /proc/bus/usb type usbfs (rw)

#mount (2nd drive added)
rootfs on / type rootfs (rw)
/dev/root on / type squashfs (ro)
none on /dev type devfs (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
ramfs on /tmp type ramfs (rw)
devpts on /dev/pts type devpts (rw)
devpts on /proc/bus/usb type usbfs (rw)

Think I'm missing something, was I supposed to mount a partition manually somehow?
(sorry, I may need to be spoon-fed what to do)
I haven't wiped OPT yet, should I do that and start fresh to get your latest update?

PS: Thanks for all the quick replies.
(6:50am here so I'm off to bed. I have to be up in ~5hrs though, so I can test some more then)

[frater]

Ok... have some sleep....

Let's assume DD-WRT is sometimes mounting 1 blockdevice as /dev/sda and then as /dev/sdb
This means some other partition gets mounted as /opt

We don't want this!

Use my (untested, but I think it's alright) code to mount a certain partition by giving its size and its partition number as a reference (what's in prt=).

Maybe your troubles are over then.

[twig123]

Ok, this is what I got:
# cat /proc/partitions
major minor #blocks name

31 0 256 mtdblock0
31 1 7872 mtdblock1
31 2 6399 mtdblock2
31 3 64 mtdblock3
31 4 128 mtdblock4
8 0 1953514583 sda
8 1 1937714172 sda1
8 2 1 sda2
8 3 10486784 sda3
8 5 5310464 sda5
8 16 160836480 sdb
8 17 4192933 sdb1 (My OPT part.)
8 18 4192965 sdb2
8 19 4192965 sdb3
8 20 148255852 sdb4

Put my block size in prt=
