I'm following up with a deploy of a new box.

I just checked new and old boxes for disk space:

OLD:

Filesystem      Size  Used Avail Use% Mounted on
/dev/xvda1      7.8G  2.7G  4.8G  36% /
none            4.0K     0  4.0K   0% /sys/fs/cgroup
udev            3.7G  8.0K  3.7G   1% /dev
tmpfs           752M  216K  752M   1% /run
none            5.0M     0  5.0M   0% /run/lock

none            100M     0  100M   0% /run/user
/dev/xvdb        30G   45M   28G   1% /mnt

NEW:

Filesystem      Size  Used Avail Use% Mounted on
/dev/xvda1      7.8G  1.2G  6.2G  16% /
none            4.0K     0  4.0K   0% /sys/fs/cgroup
udev            3.7G  8.0K  3.7G   1% /dev

/dev/xvdb        30G   45M   28G   1% /mnt

So it looks like we are not critically running out of space just yet.

I modified the install script at https://github.com/saasbook/rag/blob/master/ubuntu-install.sh so that it points to the saasbook master rather than your fork of it and have set it running on a fresh box:

After entering the ssh key I got these errors:

$ sudo chmod 0600 id_rsa
chmod: cannot access ‘id_rsa’: No such file or directory

$ source /usr/local/rvm/scripts/rvm
./install.sh: line 29: /usr/local/rvm/scripts/rvm: No such file or directory

$ cd /home/ubuntu/rag/

$ git checkout autograder_engine_refactor
Branch autograder_engine_refactor set up to track remote branch autograder_engine_refactor from origin.
Switched to a new branch 'autograder_engine_refactor'

$ rvm use 2.2.2
./install.sh: line 29: rvm: command not found

$ gem install bundler
./install.sh: line 29: gem: command not found

$ bundle-install-ifmissing
./install.sh: line 20: bundle: command not found
$ bundle install
./install.sh: line 34: bundle: command not found

I've made a few fixes to the script, and got to the bundle bit, but that fails like so:

Installing json 1.8.3 with native extensions

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Make sure that `gem install json -v '1.8.3'` succeeds before bundling.

fixed that with:

$ sudo apt-get install libgmp3-dev # http://stackoverflow.com/questions/21603772/usr-bin-ld-cannot-find-lgmp

That allowed the bundle to complete and then I was able to copy over the config from the main grader into config/config.yml

I now have a new grader up on the production queue, and that seems to be working. The old grader had got totally stuck so I have taken that one offline for the moment.
