Hi!

I just got myself a Sheevaplug and installed Meteohub with SD image which is working just fine.

Now I just started to think about installing Meteohub on external usb hdd. Obviously I would have to use powered usb hub with the disk to get both hdd and my WMR-200 connected.

What steps should I take to achieve this? Of course, backup old data, write image to hdd, repartition the hdd, import old data but what else?

I wouldn't recommend doing that, because having the root disk connected via USB is not a very reliable option as far as my experiences with NSLU2 do tell me.

Why do you want to do that? It is more bulky, makes noise, wastes power and USB HDDs are known not to be built for 24/7 operation.

Well, I plan to put several services on the plug that now I have on different servers (old laptop, two NSLUs).

Noise, bulkiness and power are not issues since I'm reducing machines and plug is in storage room where noise isn't any problem.

And the hdd is actually quality hdd in external case not just any cheap usb disk. Sorry, I should've been more exact about that.

I used to have that same disk attached to my old NSLU Meteohub and didn't have any problems with booting from that drive, but of course, anything is possible and probably now as I said that, I will run into every thinkable problem! :P

Ah, I see. When you already have experience with running your NSLU2 on a USB HDD, then switching over your SheevaPlug should be the same. "/etc/fstab" will need some tweaking and you will have to tell SheevaPlugs "uboot" that it shouldn't boot from SD anymore.

That should be all... apart from the things that don't come into my mind at the moment ;-)

Fstab tweaking seemed obvious to me but Sheevas uboot is a bit mystery to me at the moment.

So any advice on that? Or something simple enough to read about it? ;)

uboot supports environment settings that control boot process. First of all you have to connect via serial console and abort boot process when uboot provides an option to enter it's shell. uboot shell allows you to give parameters, change environment settings and to make settings permanent.

Start reading here (USB example might fit):

Well, managed to get SP boot from usb with that wiki example.

But now that I connect WMR-200 through usb hub, it collects data for about an hour and after that it doesn't receive any data from sensors. On meteohub log shows that Meteohub disconnects and connects weather station again and again. Any advice?

Posted: **Sat Oct 24, 2009 6:54 pm**

Could you please provide the "meteohub log" and "dmesg log". May be this gives some indication of what is going wrong.

Posted: **Sun Oct 25, 2009 6:54 am**

I went back from usb boot to sd boot, still keeped weatherstation plugged in to usb hub => "sensors" page shows "last signal: never" to all sensors and "weather station" page shows connection with wmr-200

There were number of these cycles in meteohub log:

Did you try without USB HUB?

yes, it works just fine without hub. But since I wanted to use plug with hdd, I need to use the hub so... :(

Different hub maybe..?

Posted: **Sun Oct 25, 2009 8:06 pm**

On my sheevaPlug Meteohub can handle a wmr100 connected to it via USB HUB. So it looks like the HUB can make the difference. Dou you have a usb-1.0 type of hub or full usb-2.0 support?

Posted: **Mon Oct 26, 2009 8:32 am**

The hub is full 2.0 supported so that shouldn't be an issue.

Anyway, I did some reading about Sheeva & hubs and found out that SheevaPlug seems to be quite picky with usb hubs. See thread on PlugForum: http://plugcomputer.org/plugforum/index.php?topic=172.0

So I guess I have to try different brand hub. I'll report here how I survived...

Posted: **Mon Oct 26, 2009 8:43 am**

Btw, I have lots (about 50 rows) of these errors in meteohub log, any ideas about these:

Code: Select all

Hubs DO make a difference: I had old bus powered Belkin USB 1.1 hub which worked fine with WMR-200. Anyway, I couldn't use it since it didn't provide enough power to my disk. :dry:

So I bought Deltaco branded USB 2.0 hub with power adapter => no data from sensors.

Can anyone recommend self powered usb hub which works fluently with WMR-200?
