[chef] How to mark a ruby_block as failed?

[Jonathan Weiss < >]

Cheers,


I'm using a ruby_block to handle complex operations with mdadm in
Chef. My question is, how do I tell Chef that my block failed and
execution should halt with an error? In pseudo code:

ruby_block "A complex operation" do
  block "using mdadm" do
    output = `do something`
    if $?.success?
      Chef::Log.info output
    else
      Chef::Log.error output
      # tell chef we failed
    end
  end
end

This would of course be easier if I could just use the execute
resource in the ruby_block...

Thanks,
Jonathan
