Folks,

may I ask you to clarify the following:

1. Is it possible to use knife to find all nodes with certain role in run list and change this role to another role?

yes, you can use knife exec, similar to this,

http://docs.opscode.com/essentials_environments_manage.html#move-nodes-between-environments
 

2. When I do "knife node run_list add some_node some_role" a recipe with name "some_role" is added to run list, not node, what do I need to add role and not recipe?

 

you have to use "recipe[some]" or "role[some_role]" , that explicitly specifies whether its role or recipe

3. After doing previous step command "knife node run_list remove some_node some_role" doesn't remove newly added recipe with name "some_role", is this expected?
4. After changing manually roles on certain nodes from "old_role" to "new_role" I see via "knife search node "platform_version:10.04" that run list is ok, but roles still mention "old_role", why is this so?

did you run chef-client on those nodes after you manually updated the runlist? roles and recipes will be updated after a successful convergence

I'm using latest chef server (11.06) and knife 10.18.0

Thanks,
Kirill.
