[chef] Re: strange behavior in chef-server

[Gilles Devaux < >]

I have solved the first issue, my bad between 'default' and 'override'

I have also solved the second issue but I believe there is a bug in the 
client when dealing with arrays

if the role file defines:
backends => [
                      { :name => "ws1", :ip => "IP" },
                      { :name => "ws2", :ip => "IP2" }
                    ],

after upload and update on the client
then knife node show NODE > dump.json

returns
    "haproxy": {
      "listenip": "173.203.240.198",
      "backends": [
        {   
          "name": "ws1",
          "ip": "173.203.240.235"
        },  
        {   
          "name": "ws2",
          "ip": "173.203.240.235"
        },  
        {   
          "name": "ws1",
          "ip": "173.203.240.235"
        },  
        {   
          "name": "ws2",
          "ip": "173.203.240.235"
        }   
      ]
for the 'attribute' section

-> the list is duplicated

When I define the role file as follow:
:backends =>
                        {
                          :ws1 => "173.203.240.235",
                          :ws2 => "173.203.240.235"
                        },

and change the template accordingly

Then everything works as expected

Thanks
