[tahoe-dev] ODROID-U2 (linux) tahoe-lafs 1.10.0 initial report

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

Here is a big fat graph

I like this way of watching my grid

In the directory with setup.py, try
python setup.py trial

or, to see more options, none of which I've played with except build :)
python setup.py --help-commands

By trial what do you mean? Is there a setup someplace I can test it? I have
done several every bit verify operations. 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.

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.

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.

My ODROID-U2, Debian Wheezy, LXFE has successfully arrived, booted from
MicroSD, and run.

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!
