Guillaume Abrioux c373bfa00c osd: move systemd rendering task
This commit moves the systemd rendering task into `systemd.yml` file.
Otherwise, when running docker to podman playbook, the systemd unit file
isn't updated as it should be.

Guillaume Abrioux 8a154ae14a osd: change lvm bindmount
This commit makes the bindmount a bit more generic, otherwise it
currently makes the OSDs failing to start in an OSP FFU upgrade
(with RHEL7 > RHEL8 OS upgrade).
docker2podman playbook is run from ceph-ansible stable-3.2 branch
against RHEL7 nodes where `/var/run/lvmetad.socket` exists but once the
system is upgraded to RHEL8, this socket doesn't exist anymore and
prevent OSDs from starting after the reboot.

As a workaround we can make this bindmount a bit more generic like what
is done in `stable-4.0` branch by mounting `/run/lvm` instead.

Guillaume Abrioux 90f3f61548 infra: introduce docker to podman playbook
This isn't backported from master because there are too many changes
between stable-3.2 and other newer branches.

NOTE:
This playbook  *doesn't* add podman support in stable-3.2 at all.
This is a tripleO dedicated playbook which is intended to be run
early during FFU workflow in order to prepare the OS upgrade.

Dimitri Savineau 7d2b29d0eb ceph-osd: Add ulimit nofile on container start
On containerized deployment, the OSD entrypoint runs some ceph-volume
commands (lvm/simple scan and/or activate) which perform badly without
the ulimit option.
This option was added for all previous ceph-volume commands but not on
the ceph-osd container startup.
Also updating hard limit value to 4096 to reflect default baremetal
value.

Guillaume Abrioux 81906344ee osd: copy systemd-device-to-id.sh on all osd nodes before running it
Otherwise it will fail when running rolling_update.yml playbook because

The task which copies the script is run against the current node being

Dimitri Savineau bedc0ab69d ceph-osd: use OSD id with systemd ceph-disk
When using containerized deployment we have to create the systemd
service unit based on a template.
The current implementation with ceph-disk is using the device name
as paramater to the systemd service and for the container name too.

$ systemctl start ceph-osd@sdb
$ docker ps --filter 'name=ceph-osd-*'
CONTAINER ID IMAGE                        NAMES
065530d0a27f ceph/daemon:latest-luminous  ceph-osd-strg0-sdb

This is the only scenario (compared to non containerized or
ceph-volume based deployment) that isn't using the OSD id.

$ systemctl start ceph-osd@0
$ docker ps --filter 'name=ceph-osd-*'
CONTAINER ID IMAGE                        NAMES
d34552ec157e ceph/daemon:latest-luminous  ceph-osd-0

Also if the device mapping doesn't persist to system reboot (ie sdb
might be remapped to sde) then the OSD service won't come back after
the reboot.

This patch allows to use the OSD id with the ceph-osd systemd service
but requires to activate the OSD manually with ceph-disk first in
order to affect the ID to that OSD.

Dimitri Savineau f4212b20e5 ceph-volume: Set max open files limit on container
The ceph-volume lvm list command takes ages to complete when having
a lot of LV devices on containerized deployment.
For instance, with 25 OSDs on a node it takes 3 mins 44s to list the
OSD.
Adding the max open files limit to the container engine cli when
executing the ceph-volume command seems to improve a lot thee
execution time ~30s.

This was impacting the OSDs creation with ceph-volume (both filestore
and bluestore) when using multiple LV devices.

Since all files in container image have moved to `/opt/ceph-container`
this check must look for new AND the old path so it's backward

Guillaume Abrioux 4cc1506303 osd: commonize start_osd code
since `ceph-volume` introduction, there is no need to split those tasks.

Let's refact this part of the code so it's clearer.

By the way, this was breaking rolling_update.yml when `openstack_config:
true` playbook because nothing ensured OSDs were started in ceph-osd role (In
`openstack_config.yml` there is a check ensuring all OSD are UP which was
obviously failing) and resulted with OSDs on the last OSD node not started
anyway.

Sébastien Han 5132cc3de4 Do not search osd ids if ceph-volume
Description of problem: The 'get osd id' task goes through all the 10 times (and its respective timeouts) to make sure that the number of OSDs in the osd directory match the number of devices.

This happens always, regardless if the setup and deployment is correct.

Version-Release number of selected component (if applicable): Surely the latest. But any ceph-ansible version that contains ceph-volume support is affected.

How reproducible: 100%

Steps to Reproduce:
1. Use ceph-volume (LVM) to deploy OSDs
2. Avoid using anything in the 'devices' section
3. Deploy the cluster

Actual results:

}

STDOUT:

0
1
2

Expected results:
There aren't any (or just a few) timeouts while the OSDs are found

Additional info:
This is happening because the check is mapping the number of "devices" defined for ceph-disk (in this case it would be 0) to match the number of OSDs found.

Basically this line:

    until: osd_id.stdout_lines|length == devices|unique|length

Means in this 2 OSD case it is trying to ensure the following incorrect condition:

    until: 2 == 0

Andy McCrae 4671b9e74e Allow ceph service systemd overrides to be specified
ceph services can fail to start under certain circumstances (for
example, when running in a container) because the default systemd
service configuration causes namespace issues.

To work around this we can override the system service settings by
placing an overrides file in the ceph-<service>@.service.d directory.
This can be generic so as to allow any potential changes required to
the ceph-<service> service files.

The overrides file is only setup when the
"ceph_<service>_systemd_overrides" config_template override variable is
specified.

The available service systemd override files are as follows:
ceph_mds_systemd_overrides
ceph_mgr_systemd_overrides
ceph_mon_systemd_overrides
ceph_osd_systemd_overrides
ceph_rbd_mirror_systemd_overrides
ceph_rgw_systemd_overrides
