Version 1.9.0

[1.9.0] - 2022-07-19

New Features

• Add support for attaching LVM cache to existing LVs (#273)

Fixes: #252

• Add support for managing pool members (#264)

For LVM pools this adds support for adding and removing members
(PVs) from the pool (VG).

• Do not allow removing members from existing pools in safe mode

Bug Fixes

• loop variables are scoped local - no need to reset them (#282)

If you use

loop_control:
loop_var: storage_test_pool

Then the variable storage_test_pool is scoped local to the task
and is undefined after the task. In addition, referencing the
variable after the loop causes this warning:

[WARNING]: The loop variable 'storage_test_pool' is already in use. You should
set the `loop_var` value in the `loop_control` option for the task to something
else to avoid variable collisions and unexpected behavior.

• support ansible-core-2.13 (#278)

Looks like ansible-core-2.13 (or latest jinja3) does not support
constructs like this:

var: "{{ [some list] }} + {{ [other list] }}"

instead, the entire thing has to be evaluated in the same jinja
evaluation context:

var: "{{ [some list] + [other list] }}"

In addition - it is an Ansible antipattern to use

- set_fact:
var: "{{ var + item }}"
loop: "{{ some_list }}"

so that was rewritten to use filters instead

Other Changes

• ensure role works with gather_facts: false (#277)

Ensure tests work when using ANSIBLE_GATHERING=explicit

• ensure cryptsetup is available for testing (#279)

• make min_ansible_version a string in meta/main.yml (#281)

The Ansible developers say that min_ansible_version in meta/main.yml
must be a string value like "2.9", not a float value like 2.9.

• Skip the entire test_lvm_pool_members playbook with old blivet (#280)

Multiple bugs in blivet were fixed in order to make the feature
work and without the correct version even the most basic test to
remove a PV from a VG will fail so we should skip the entire test
with old versions of blivet.
Skip test on el7 if blivet version is too old
Add support for is_rhel7
Refactor EL platform and version checking code
Add a name for the end_play task

• Add CHANGELOG.md (#283)
