This release breaks with backward compatibility.

functionality / parameters that have been removed:
  • cgroups::cgconfig_mount

To keep the old behaviour with hiera you can add the old default values to your osfamily-release structure (eg %{osfamily}-%{operatingsystemrelease})

RedHat-6.yaml:

cgroups::mounts:
  cpu: '/cgroup'

Suse-11.yaml:

cgroups::mounts:
  cpu: '/sys/fs/cgroup'

Do not use this fix on RedHat 7 clients until you know exactly what you are doing.

####Features

  • Add cgroups::mount parameter without hard coded defaults for more flexibility as successor of cgconfig_mount.
  • Add cgroups::group defined resource type to place group definitions in the .d directory instead of main configuration file.
  • Add cgroups::group::target_path to allow usage of specific configuration paths.
  • Add cgroups::groups parameter for optionally adding cgroups::group types (via hiera for example).
  • Add support for RedHat 7.

####Bugfixes

  • Remove usage of $::lsbmajdistrelease in favour of $::operatingsystemrelease .
  • Enhance the spec tests to feature much more test cases.

####Upgrading from 1.x When upgrading from version 1.x you need to migrate your cgroups::cgconfig_mount entries into the new cgroups::mounts format. The new format is a hash for greater flexibility. You have to add the subsystem for your mounts.

In most cases it should be good enough to change the parameter name, make it a hash and add the 'cpu' subsystem as key.

#####Hiera Example: old deprecated string format

cgroups::cgconfig_mount: '/cgroup'

new hash format

cgroups::mounts:
  cpu: '/cgroup'
