[Puppet Users] how to ensure LVM created before installing postgres

[Alex Samad]

Hi

I would like to setup my LVM first 
PV
VG
PV 
mount that in /var/lib/pgsql/9.2/data and then use

# default
    class { 'postgresql::globals':
      manage_package_repo => false,
      version             => '9.2',
    }->
      class { 'postgresql::server':
      }


now for testing I haven't installed /dev/sdc which is my phys disk for the 
vg..

I would like the install of postgress to fail



    # predefined mounts
    # not done via lvm - can't do labels !

    # setup PG Data directory first
    file { '/var/lib/pgsql':
      ensure   => 'directory',
      group    => '26',
      mode     => '0700',
      owner    => '26',
    }

    file { '/var/lib/pgsql/9.2/':
      ensure   => 'directory',
      group    => '26',
      mode     => '0700',
      owner    => '26',
    }

    # incuded as part of the postgres module
#    file { '/var/lib/pgsql/9.2/data':
#      ensure   => 'directory',
#      group    => '26',
#      mode     => '0700',
#      owner    => '26',
#    }

    filesystem { '/dev/vg_pgdata/lv_pgdata':
      ensure => 'present',
      fs_type => 'ext4',
      options => '-L ybPGData',
    }

    mount { '/var/lib/pgsql/9.2/data':
      ensure  => 'mounted',
      device  => 'LABEL=ybPGData',
      dump    => '1',
      fstype  => 'ext4',
      options => 'defaults',
      pass    => '2',
      target  => '/etc/fstab',
    }

    volume_group { 'vg_pgdata':
      ensure => present,
      physical_volumes => '/dev/sdc1'
    }

    logical_volume { 'lv_pgdata':
      ensure => present,
      volume_group => 'vg_pgdata',
      size => '20G',
    }



    #
    # latest postgres rpm
    #
    package { 'pgdg-centos92-repo':
      name => 'pgdg-centos92',
      ensure => 'installed',
      provider => 'rpm',
      source => 
'https://download.postgresql.org/pub/repos/yum/9.2/redhat/rhel-6-x86_64/pgdg-centos92-9.2-7.noarch.rpm',
      install_options => [
        '--httpproxy',
        'proxyyb',
        '--httpport',
        '3128',
      ]
    }

    # have to overwrite the repo file
    file { 're_pgdg-centos92':
      ensure => present,
      path => '/etc/yum.repos.d/pgdg-92-centos.repo',
      content => file('profile/ybpostgresql92/pgdg-92-centos.repo'),
      owner => 'root',
      group => 'root',
      mode => 'u=rw,g=r,o=r',
    }


    # default
    class { 'postgresql::globals':
      manage_package_repo => false,
      version             => '9.2',
    }->
      class { 'postgresql::server':
      }
