Ahh - we've used very different strategies.  I've never used PIP at all, and my one apt-get install tahoe experiment failed.  You're clearly a more advanced python user than I am at this point.

I simply download the source code build, unzip it to allmydata.... (using a non-root, regular user), and then, still with the regular user:

When you say yours pass trial, how do you run the trial?  I use:
python setup.py trial


Possibly: apt-get install python-dev
cd all*
python setup.py build

At which point it's ready to go.  I find the idea of "unzip and execute one command" to get it running very easy - even on the raspberry pi, building takes very little time.  the trial, well, that takes a lot more (and ~800MB total RAM, more or less, with a light GUI, on x86).

To test and use:
python setup.py trial
cd bin
./tahoe create-node
...
python tahoemenu.py
...
etc.

Very nice graphs, by the way!  Not much traffic, though - 1-2KB/s network, and that's probably the monitoring monitoring the monitoring.

When you install tahoe with PIP where is the build files located? I suppose I could build one on the Atom Blade but my results with the trial have always passed. I like to use the pip build because its fast and I have set up virtualenv for Python builds. That was the main reason I formatted the drive because prior to this build I did it from scratch and I wanted a more auto install to test. I have used Newrelic to monitor the metrics. The python collector for newrelic is a bit corky I have yet to install that into tahoe. Here is a small status on my webpage http://netgreen.us/page/grid-status Here is a big fat graph https://dashboard.graphdat.com/627/Mr%20Keepins%20GRID?from=1381117317816&to=1381117437816 I like this way of watching my grid Jason From: Garonda Rodian [mailto:deepside at hotmail.com]

python setup.py trial

or, to see more options, none of which I've played with except build :)

The biggest one being on a folder I had to make healthy again. I am not uploading files larger then 1g currently. I would like to put a monitor of some kind on the bones. So far they are running well. What would you suggest I use for monitoring them? I ask because there are lots of tools and I would like to stay within tahoe dev realm of things.Here is a pic of it for shows and such. There is a camera in the middle for taking peoples pics that stare at it for more than a few min. That’s running motion. Jason From: Garonda Rodian [mailto:deepside at hotmail.com]

Subject: RE: [tahoe-dev] ODROID-U2 (linux) tahoe-lafs 1.10.0 initial report How fast does the Atom blade run the trial?  I'm assuming the BeagleBone Blacks can't complete it due to lack of RAM.

Do the BeagleBone Blacks have a hardware watchdog?

Separately, how many "Every bit" verify operations have you done, and how well did they go?  

For anyone else trying an ODROID-U2, I'm using the image from 

 I found out you have to do cp /boot/boot-hdmi-1080p60hz.scr /boot/boot.scr in order to get HDMI working properly at 1920x1080.  I'm still working on getting files to it, after which I should be able to really try some intertesting!

Are there any benchmarking modes for tahoe-lafs?  I'd like to see the throughput for the encryption step, and for the zfec step, and the hashing, etc., to be able to compare setups.Date: Wed, 16 Oct 2013 09:16:58 -0500

This is cool! Currently I have 8 beaglebone blacks and a small Atom blade as the introducer and helper. I am looking for people to connect to my grid for testing. I even took the hard drive out of the introducer and one node formated them and put tahoe 1.10 i was able to repair the grid no prob.

python setup.py build failed just after it didn't find tahoe-deps, until I installed my usual set of packages (including, but not limited to, python-dev), after which it worked fine.  

python setup.py trial succeed with 6 skipped and 2 expected failures in something over 1500 seconds, typically using 100% of one out of four cores, and the maximum amount of total RAM in use I happened to see (htop) was on the order of 561MB - since it has 2GB of RAM, that's more than fine.

Further testing to follow - I have high hopes it can serve as an introducer + storage nodes, or even a helper/client gateway.  If I can get a Gigabit USB2 card working, perhaps it'll even break the 10MB/s limit as a storage node!
