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
{% else %} False {% endif %}): expected string or buffer.

Since the default of `osd_objectstore` has changed as of 3.2, some
deployments might have a mix of filestore and bluestore OSDs on a same
node. In some specific cases, there's a possibility that a filestore OSD
shares a journal/db device with a bluestore OSD. We shouldn't try to
redeploy in this context because ceph-volume will complain. (either
because in lvm batch you can't pass partition or about gpt header).
The safest option is to skip the migration on the node when such a mix
is detected or force all osds including those already using bluestore
(option `force_filestore_to_bluestore=True` has to be passed as an extra var).
If all OSDs are using filestore, then they will be migrated to

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
and/or facts which could consume resources for nothing.
When checking the pgs state, we're using the pgmap structure in the ceph
status output.
To optimize this, we could use the ceph pg stat command which contains
the same needed information.
This command returns less information (only about pgs) and is slightly
faster than the ceph status command.
$ ceph status -f json | wc -c
2000
$ ceph pg stat -f json | wc -c
240
$ time ceph status -f json > /dev/null
real 0m0.529s
user 0m0.503s
sys 0m0.024s
$ time ceph pg stat -f json > /dev/null
real 0m0.426s
user 0m0.409s
sys 0m0.016s
The data returned by the ceph status is even bigger when using the
nautilus release.
$ ceph status -f json | wc -c
35005
$ ceph pg stat -f json | wc -c

Instead of using ceph auth get command via the ansible command module
then we can use the ceph_key module and the info state.
