The machinectl cache is currently set image to 16G by default. If multiple container images are imported into the cache this may be too small by default. This change sets the cache to "64G" by default allowing the cache more room to grow by. This change also disables the quota system once the limit has been set The option `lxc_host_machine_quota_disabled` has been added to disable or enable the quota system as needed. This is done after the default limit has been set so an adequately sized sparce file can be created should it not already exist. > More documentation can be seen here [0] with regard to the set-limit option. Because we support both modern and older systemd, the cache prep tasks for old systemd have been updated so that deployers using earlier versions of systemd can benefit from the ability to grow an existing cache via playbook run.

upgrade:
|
|
- The variable ``lxc_host_machine_volume_size`` now accepts any valid size
|
|
modifier acceptable by ``truncate -s`` and ``machinectl set-limit``.
|
|
prior to this change the option assumed an integer was set for some value
|
|
in gigabytes. All acceptable values can be seen within the
|
|
`documentation for machinectl <https://www.freedesktop.org/software/systemd/man/machinectl.html#set-limit%20%5BNAME%5D%20BYTES>`_
|
|
features:
|
|
- An option to disable the ``machinectl`` quota system has been added. The
|
|
variable ``lxc_host_machine_quota_disabled`` is a Boolean with a default of
|
|
**true**. When this option is set to **true** it will disable the
|
|
``machinectl`` quota system.
|
|
other:
|
|
- The variable ``lxc_host_machine_volume_size`` is used to set the size of
|
|
the default sparse file as well as define a limit within the ``machinectl``
|
|
quota system. When the ``machinectl`` quota system is enabled deployers
|
|
should appropriately set this value to the size of the container volume,
|
|
even when not using a sparse file.
|
|
- The container image cache within machinectl has been set to "64G" by
|
|
default.
