Here's an example of using an execute resource in a ruby_block. I'm not aware 
of an easier semantic.

ruby_block "A complex operation" do
  block do
    run_context = Chef::RunContext.new(node, {})
    e = Chef::Resource::Execute.new("Something with mdadm", run_context)
    e.command("put the command/commands here. multi-line with ruby here 
document")
    e.run_action(:run)
  end
end

The key here is the run_context and the Chef::Resource syntax.
