The balancer status is registered during the cephadm-adopt, rolling_update
and swith2container playbooks. But it is also used in the ceph-handler role
which is included in those playbooks too.
Even if the ceph-handler tasks are skipped for rolling_update and
switch2container, the balancer_status variable is erased with the skip task
result.
play1:
register: balancer_status
play2:
register: balancer_status <-- skipped
play3:
when: (balancer_status.stdout | from_json)['active'] | bool
This leads to issue like:
The conditional check '(balancer_status.stdout | from_json)['active'] | bool'
failed. The error was: Unexpected templating type error occurred on
({% if (balancer_status.stdout | from_json)['active'] | bool %} True

When deploying the ceph OSD via the packages then the ceph-osd@.service
unit is configured as enabled-runtime.
This means that each ceph-osd service will inherit from that state.
The enabled-runtime systemd state doesn't survive after a reboot.
For non containerized deployment the OSD are still starting after a
reboot because there's the ceph-volume@.service and/or ceph-osd.target
units that are doing the job.
$ systemctl list-unit-files|egrep '^ceph-(volume|osd)'|column -t
ceph-osd@.service enabled-runtime
ceph-volume@.service enabled
ceph-osd.target enabled
When switching to containerized deployment we are stopping/disabling
ceph-osd@XX.servive, ceph-volume and ceph.target and then removing the
systemd unit files.
But the new systemd units for containerized ceph-osd service will still
inherit from ceph-osd@.service unit file.
As a consequence, if an OSD host is rebooting after the playbook execution
then the ceph-osd service won't come back because they aren't enabled at
boot.
This patch also adds a reboot and testinfra run after running the switch
to container playbook.

The ceph status command returns a lot of information stored in variables

When rgw and osd are collocated, the current workflow prevents from
scaling out the radosgw_num_instances parameter when rerunning the
playbook.
The environment file used in the rgw systemd template is rendered when
executing the `ceph-rgw` role but during a new run of the playbook (in
order to scale out rgw instances), handlers are triggered from `ceph-osd`
role which is run before `ceph-rgw`, therefore it tries to start the new
rgw daemon whereas its corresponding environment file hasn't been
rendered yet and fails like following:
```
ceph-radosgw@rgw.ceph4osd3.rgw1.service failed to run 'start-pre' task: No such file or directory
```
This commit moves the tasks generating this file in `ceph-config` role
so it is generated early.

If the OSD is encrypted (dmcrypt: true) then there's an additional

Because this partition isn't umount then the containerized OSD aren't

By changing the set ownership command from using the file module in combination with a with_items loop to a raw chown command, we can achieve a 98% performance increase here.
On a ceph cluster with a significant amount of directories and files in /var/lib/ceph, the file module has to run checks on ownership of all those directories and files to determine whether a change is needed.

This commit splits the current `ceph-container-common` role.
This introduces a new role `ceph-container-engine` which handles the
tasks specific to the installation of containers tools (docker/podman).
This is needed for the ceph-dashboard implementation for 2 main reasons:
1/ Since the ceph-dashboard stack is only containerized, we must install
everything needed to run containers even in non containerized
deployments. Splitting this role allows us to not have to call the full
`ceph-container-common` role which would run a bunch of unneeded tasks
that would have been skipped anyway.
2/ The current implementation would have required to run
`ceph-container-common` on all ceph-clients nodes which would have been
conflicting with 9d3517c670 (we don't want
to run ceph-container-common on all client nodes, see mentioned commit
for more details)
