This is a simple tool to help you determine whether all your Wikimedia Labs instances are ready for the datacenter migration from pmtpa (Tampa) to eqiad (Ashburn). Currently there are four checks:

1. Check if you are running a self hosted puppet master
2. Check if your last puppet run is recent, less than 30 days old
3. Check if you are using shared project space ie /data/projects/
4. Check if you are using shared storage for $HOME

sudo python setup.py install

this will install all the dependencies and you should be good to go.

The command to run the script is easy:

cd labs-migration-assistant
fab test --set wiki_username=YOUR_WIKI_USERNAME
# use your username for Wikitech

Development of this script was done using Python 2.7.5 on OSX 10.9. I expect that this would work fine on Python 2.5 and 2.6 as well and I do not foresee problems with Linux either. But....bug reports are always welcome and pull requests even more!

Use a recent version of pip (1.2 or higher)

Sometimes a lab instance might be totally unresponsive and SSH will not time-out. If that happens then abort the script using CTRL+Z or CTRL+C and then invoke the labs migration assistant as follows

fab test --set wiki_username=YOUR_WIKI_USERNAME --exclude_hosts=host1,host2

You should only use the name of the instance, not the FQDN.

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes, including tests (git commit -am 'Added some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request, and mention @dvanliere.
