Cannot apply a cs_location to a group of resources

[tullis]

I'm unable to apply a cs_location type to a group of resources. Am I missing something, or has it not yet been implemented?

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 3.8.5
• Ruby: 2.1.5p273
• Distribution: Debian Jessie
• Module version: 5.0.0

How to reproduce (e.g Puppet code you use)

I'm trying to apply a cs_location type to a previously created cs_group but it doesn't work.

I have tried using the following puppet code:

  cs_location { 'ns1_internal_gw1':
    primitive => 'ns1_vips', # <- Name of group resource
    node_name => 'gw1',
    score     => '200',
  }

and

  cs_location { 'ns1_internal_gw1':
    primitive => Cs_group['ns1_vips'],
    node_name => 'gw1',
    score     => '200',
  }

I have had to resort to configuring a cs_location type for each member of the group, or creating the location constraints outside of puppet.

What are you seeing

These are the error messages displayed by my puppet client

ERROR: constraint ns1_vips_gw1 references a resource ns1_vips which doesn't exist

ERROR: constraint ns1_vips_gw1 references a resource Cs_group[ns1_vips] which doesn't exist

What behaviour did you expect instead

I would have expected to be able to apply a cs_location type to a group of resources.

That error message means that crm expects another syntax for location that imply groups.

Can you please add the location by hand : do a crm configure show and paste the crm configure show output for that location?

Thanks

Hi,

Thanks for the response.

Here is where I add four location constraints in by hand, using the crm shell.

crm(live)# configure location ns1_gw1 ns1_vips 200: gw1
crm(live)# configure location ns1_gw2 ns1_vips -1: gw2
crm(live)# configure location ns2_gw1 ns2_vips -1: gw1
crm(live)# configure location ns2_gw2 ns2_vips 200: gw2

Here is the portion of the crm configure show which shows the four location constraints.

location ns1_gw1 ns1_vips 200: gw1
location ns1_gw2 ns1_vips -1: gw2
location ns2_gw1 ns2_vips -1: gw1
location ns2_gw2 ns2_vips 200: gw2

If I use the puppet module as is, and I have to select primitives rather than groups for the location constraints, I seem to have to double this to 8 constraints, because each group has two member resources.

This should work. Can you add require => Cs_group['ns1_vips'],

[tullis]

Thanks very much. I can confirm that it works with that resource ordering pattern in place.
Sorry to trouble you with user error and thanks very much for your work on this module.

[roidelapluie]

No problem. Actually I will take some action of this.

Good stuff. Is it worth adding a note about the cs_group type to the README as well, while you're at it? I had to dig into the code to check that I could use it.

[roidelapluie]

The readme should move away and be replaced by puppet-strings
