There are a couple of problems I experienced with the upgrade of Opscode Chef from 0.9 to 0.10.

No DEB packages yetImpatient as I was I wanted to upgrade before the Ubuntu deb's were released. So I uninstalled the deb install and did the ruby gem install, keeping my existing config & DB.  Perhaps I'm a bit naïve to think this should work :p

RabbitMQ not properly setup by chef-soloOnce the chef-solo bootstrap was complete I started up all the services and tried things out. It didn't work. Couldn't do the last step in the upgrade docs: knife index rebuild.

Turned out this was related to rabbitmq, which was also filling up the disk quickly with error logs.  The solution was to update the rabbitmq password: rabbitmqctl change_password chef testing.

Internal Server Error 500Another error I keep getting on some servers is
File with checksum a73b7f6222549364ab0d6c4ed2442abf not found in the repository (this should not happen) - (Merb::ControllerExceptions::InternalServerError)"It looks like there's an inconsistency between CouchDB and the filesystem cache.

The tips on chef bug #1397 explains how this can be fixed with a combination of Shef and rake install:
# shef chef > require 'chef/checksum' => false chef > r = Chef::REST.new('http://localhost:5984/chef/_design/checksums/_view/', false, false) => #<Chef::REST:0x7f831db382b8 @redirect_limit=10, @cookies={}, @redirects_followed=0, @auth_credentials=#, @url="http://localhost:5984/chef/_design/checksums/_view/", @sign_request=true, @default_headers={}, @sign_on_redirect=true> chef > r.get_rest("all")["rows"].each do |c| c["value"].cdb_destroy end
After doing this I did the rake install. During this process I had some difficulties that resulted in this error:

To resolve this problem I removed the nginx proxy from the communications chain and that resolved the problem. The problem occurred in just a single recipe, and I believe the culprit was a 2.2MB file that was failing to upload through the proxy. Yes - I know chef should not be used with 2.2MB files.

After removing the proxy from the chain it was possible to do the rake install and all worked well.
