[tahoe-dev] Newbie problems

[Randall Mason]

To setup a test cluster, you do not need VMs.  You can run multiple nodes
on the same computer.  Here is the process on any computer with bash and
Tahoe-LAFS already installed:

cd $directoryWithSpace
tahoe create-introducer test-introducer
tahoe start test-introducer
export introducerFURL=$(cat test-introducer/introducer.furl)
for testNode in $(seq 0 9);
do
  tahoe create-node testNode${testNode}
  sed -i -e 's#^introducer.furl.*#introducer.furl = '$introducerFURL'#g' -e
's#web.port = tcp:3456:interface=127.0.0.1#web.port =
tcp:345'${testNode}':interface=127.0.0.1#g'   testNode${testNode}/tahoe.cfg
  tahoe start testNode${testNode}
done;
tahoe -d testNode0/ webopen

Running the 11 nodes takes a bit of memory, but only ~65 MB a piece.  It's
quick and responsive on my 4 year old laptop with 3GB of RAM.  It uploaded
a 20MB file in a second and you can even see the files that it creates:
find . -type f| grep
