We've looked at the tutorial page that you've got, but we're trying to modify 
this cookbook to work on CentOS 5.6, and we're running into some problems.

In cookbooks/mongodb/definitions/mongodb.rb, starting at line 140, we have 
this code:

  # replicaset
  if !replicaset_name.nil?
    rs_nodes = search(
      :node,
      "mongodb_cluster_name:#{replicaset['mongodb']['cluster_name']} AND \
       recipes:mongodb\\:\\:replicaset AND \
       mongodb_shard_name:#{replicaset['mongodb']['shard_name']} AND \
       chef_environment:#{replicaset.chef_environment}"
      )

However, this search is returning null for us. We confirmed this by adding 
the following logging statement:

    Chef::Log.info("mongodb:rs_nodes:#{rs_nodes}")

The result is a chef-client run that looks like this:
173-203-195-99.static.cloud-ips.com [Thu, 15 Sep 2011 23:43:43 +0000] WARN:

commandline

Processing gem_package[mongo] action install (mongodb::default line 34)

We're having trouble figuring out why this search would be returning null, 
and our forays with Shef and all of our other testing so far have not been 
very enlightening.

I tried posting this as a comment at 
<http://community.opscode.com/cookbooks/mongodb>, but all the formatting was 
destroyed in that message, and there doesn't seem to be any way that I can 
delete a comment that I had made.


I don't suppose you have any hints or comments?  Thanks!
