lvm module help

[dkoleary]

Hey, all;

I'm having some trouble getting the lvm module to work the way I think it should based on my probable erroneous reading of the documentation.

I would like to ensure a logical volume of 2gs is created in vg00 which has plenty of free space to handle the lv creation.  I've been using this link as the guide:  

https://github.com/puppetlabs/puppetlabs-lvm

I'm using the puppetforge lvm module.

Hiera data looks like:

---
lvm::volume_groups:
  vg00:
    createonly: true
    physical_volumes:
      /dev/sda2:
        unless_vg: 'vg00'
    logical_volumes:
      audit:
        size: 2G

I get this error when running on a test box:

# puppet agent -t
Notice: Local environment: 'production' doesn't match server specified node environment 'dkoleary', switching agent to 'dkoleary'.

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Evaluation Error: Error while evaluating a Resource Statement, Lvm::Volume_group[vg00]: has no parameter named 'createonly' on node myhost.mydomain.com
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run

If i comment the hiera data and specify the parameters directly in the class, it works:

# == Class: lvm
#
 
class lvm {


  physical_volume { '/dev/sda2':
    ensure    => present,
    unless_vg => 'vg00',
  }


  volume_group { 'vg00':
    ensure           => present,
    physical_volumes => '/dev/sda2',
    createonly       => true,
  }


  logical_volume { 'audit':
    ensure       => present,
    size         => '2G',
    volume_group => 'vg00',
  }
}
#======================================================================
# original init.pp code
#======================================================================
# class lvm (
#   $package_ensure = 'installed',
#   $manage_pkg     = undef,
#   $volume_groups  = {},
# ) {

#   if $manage_pkg {
#     package { 'lvm2':
#       ensure   => $package_ensure
#     }
#   }
#
#   validate_hash($volume_groups)
#
#   create_resources('lvm::volume_group', $volume_groups)
# }  
#======================================================================

results in:

# puppet agent -t

I'd appreciate any hints/tips/suggestions on what I might be doing wrong.

Thanks for your time.

You list volume_groups in Hiera (with an "s"):

---
lvm::volume_groups:
  vg00:
    createonly: true
    physical_volumes:
      /dev/sda2:
        unless_vg: 'vg00'
    logical_volumes:
      audit:
        size: 2G

You list volume_group (without an "s") in your manifest:

create_resources('lvm::volume_group', $volume_groups)

If this is a typo in your copy/paste then it may be that Puppet cannot find the data in Hiera. Where do you define lvm::volume_groups in Hiera (common.yaml, node specific yaml file, etc)?

I'll give that  try.  I was retyping/copying/pasting from the link directly, figuring the forge module handled that some how.  I appreciate the suggestion.

Thanks

Hey;

Thanks again; unfortunately, that's not it.  volume_groups is set as a parameter to the lvm class:

class lvm (
  $package_ensure = 'installed',
  $manage_pkg     = undef,
  $volume_groups  = {},
) {

I tried it w/o the 's' anyways.  While the error went away, I didn't get my lv created either.  

Thanks again for the reply.
