[chef] how can i set node attribute from inside powershell_script resource

[Pradeep Kumar < >]

Hi All,

i have a boolean attribute. i want to set the attribute to true conditionally inside a powershell_script.

if the attribute is true i would like to throw a fatal error message and abort chef run.

i'm stuck on how to set the attribute value from inside the powershell.

in the below case #{node.default['saas_wfa_prod_db_server']['fail_chef']=true} is running irrespective of the if condition. (may be its evaluated during compile) 

below is the code. can some one please help.

--code--

node.default['saas_wfa_prod_db_server']['fail_chef'] = false

powershell_script "get available offline disks" do

code <<-EOH

$sysstoragelength =4

$drivestoragelength=5

if($sysstoragelength -lt $drivestoragelength)

{

#{node.default['saas_wfa_prod_db_server']['fail_chef']=true}

}

EOH

end

if (node['saas_wfa_prod_db_server']['fail_chef']) 

Chef::Application.fatal!("sufficient number of disks not available in offline state", 42) 

end
