scenario you stop other collocated services in the OSD play which isn't

Guillaume Abrioux d86a159a79 osd: ensure /var/lib/ceph/osd/{cluster}-{id} is present
This commit ensures that the `/var/lib/ceph/osd/{{ cluster }}-{{ osd_id }}` is
present before starting OSDs.

This is needed specificly when redeploying an OSD in case of OS upgrade
failure.
Since ceph data are still present on its devices then the node can be
redeployed, however those directories aren't present since they are
initially created by ceph-volume. We could recreate them manually but
for better user experience we can ask ceph-ansible to recreate them.

NOTE:
this only works for OSDs that were deployed with ceph-volume.
ceph-disk deployed OSDs would have to get those directories recreated
manually.

Guillaume Abrioux acdd43c0e2 containers: modify bindmount option
This commit changes the bind mount option for the mount point
`/var/lib/ceph` in the systemd template for mon and mgr containers. This
is needed in case of collocating mon/mgr with osds using dmcrypt
scenario.
Once mon/mgr got converted to containers, the dmcrypt layer sub mount is
still seen in `/var/lib/ceph`. For some reason it makes the
corresponding devices busy so any other container can't open/close it.
As a result, it prevents osds from starting properly.

Since it only happens on the nodes converted before the OSD play, the idea is
to bind mount `/var/lib/ceph` on mon and mgr with the `rshared` option
so once the sub mount is unmounted, it is propagated inside the
container so it doesn't see that mount point.

that doesn't seem to be 100% reproducible but it shows up after a

Benoît Knecht deaf60316a ceph-facts: Fix osd_pool_default_crush_rule fact
The `osd_pool_default_crush_rule` is set based on `crush_rule_variable`, which
is the output of a `grep` command.

However, two consecutive tasks can set that variable, and if the second task is
skipped, it still overwrites the `crush_rule_variable`, leading the
`osd_pool_default_crush_rule` to be set to `ceph_osd_pool_default_crush_rule`
instead of the output of the first task.

This commit ensures that the fact is set right after the `crush_rule_variable`
is assigned, before it can be overwritten.

Gaudenz Steinlin bb3cfd0481 config: Always use osd_memory_target if set
The osd_memory_target variable was only used if it was higher than the
calculated value based on the number of OSDs. This is changed to always
use the value if it is set in the configuration. This allows this value
to be intentionally set lower so that it does not have to be changed
when more OSDs are added later.

Dimitri Savineau ee43555148 switch2container: disable ceph-osd enabled-runtime
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.

Francesco Pantano 65a503bedc Add ceph_client tag to execute or skip the playbook
There are some use cases where there's a need to skip the execution
of the ceph-ansible client role even though the client section of the
inventory isn't empty.
This can happen in contexts where the services are colocated or when
a all-in-one deployment is performed.
The purpose of this change is adding a 'ceph_client' tag to avoid
altering the ceph-ansible execution flow but at the same time be able
to include or exclude a set of tasks using this tag.

Guillaume Abrioux e6b3186420 ceph-volume: refresh lvm metadata cache
When running rhel8 containers on a rhel7 host, after zapping an OSD
there's a discrepancy with the lvmetad cache that needs to be refreshed.
Otherwise, the host still sees the lv and can makes the user confused.
If user tries to redeploy an OSD, it will fail because the LV isn't
present and need to be recreated.

ie:

```
