Usage

If you're using Berkshelf, just add this cookbook to your Berksfile:

cookbook 'lvm'

You can also install it from the community site:

knife cookbook site install lvm

Include the default recipe in your run list on a node, in a role, or in another recipe:

run_list(
  'recipe[lvm::default]'
)

Depend on lvm in any cookbook that uses its Resources/Providers:

# other_cookbook/metadata.rb
depends 'lvm'

Caveats

This cookbook depends on the di-ruby-lvm and di-ruby-lvm-attrib gems. The di-ruby-lvm-attrib gem in particular is a common cause of failures when using the providers. If you get a failure with an error message similar to

No such file or directory - /opt/chef/.../di-ruby-lvm-attrib-0.0.3/lib/lvm/attributes/2.02.86(2)/lvs.yaml

then you are running a version of lvm that the gems do not support. However, getting support added is usually pretty easy. Just follow the instructions on "Adding Attributes" in the di-ruby-lvm-attrib README.

Development

This section details "quick development" steps. For a detailed explanation, see [[Contributing.md]].

  1. Clone this repository from GitHub:

    $ git clone git@github.com:chef-cookbooks/lvm.git
    
  2. Create a git branch

    $ git checkout -b my_bug_fix
    
  3. Install dependencies:

    $ bundle install
    
  4. Make your changes/patches/fixes, committing appropiately

  5. Write tests

  6. Run the tests:

    • bundle exec foodcritic -f any .
    • bundle exec rspec
    • bundle exec rubocop
    • bundle exec kitchen test

In detail: - Foodcritic will catch any Chef-specific style errors - RSpec will run the unit tests - Rubocop will check for Ruby-specific style errors - Test Kitchen will run and converge the recipes
