Sébastien Han 3149b2564f Revert "osd: generate device list for osd_auto_discovery on rolling_update"
This reverts commit e84f11e99e.

This commit was giving a new failure later during the rolling_update
process. Basically, this was modifying the list of devices and started
impacting the ceph-osd itself. The modification to accomodate the
osd_auto_discovery parameter should happen outside of the ceph-osd.

Also we are trying to not play ceph-osd role during the rolling_update
process so we can speed up the upgrade.

Sébastien Han e84f11e99e osd: generate device list for osd_auto_discovery on rolling_update
rolling_update relies on the list of devices when performing the restart
of the OSDs. The task that is builind the devices list out of the
ansible_devices dict only runs when there are no partitions on the
drives. However during an upgrade the OSD are already configured, they
have been prepared and have partitions so this task won't run and thus
the devices list will be empty, skipping the restart during
rolling_update. We now run the same task under different requirements
when rolling_update is true and build a list when:

* osd_auto_discovery is true
* rolling_update is true
* ansible_devices exists
* no dm/lv are part of the discovery
* the device is not removable
* the device has more than 1 sector

This is a follow up on #2628.
Even with the openstack pools creation moved later in the playbook,

Guillaume Abrioux 34e646e767 osds: do not set docker_exec_cmd fact
in `ceph-osd` there is no need to set `docker_exec_cmd` since the only
place where this fact is used is in `openstack_config.yml` which
delegate all docker command to a monitor node. It means we need the
`docker_exec_cmd` fact that has been set referring to `ceph-mon-*`
containers, this fact is already set earlier in `ceph-defaults`.

By the way, when collocating an OSD with a MON it fails because the container
`ceph-osd-{{ ansible_hostname }}` doesn't exist.

Removing this task will allow to collocate an OSD with a MON.

Andy McCrae 08a2b58d39 Allow os_tuning_params to overwrite fs.aio-max-nr
The order of fs.aio-max-nr (which is hard-coded to 1048576) means that
if you set fs.aio-max-nr in os_tuning_params it will effectively be
ignored for bluestore scenarios.

To resolve this we should move the setting of fs.aio-max-nr above the
setting of os_tuning_params, in this way the operator can define the
value of fs.aio-max-nr to be something other than 1048576 if they want
to.

Additionally, we can make the sysctl settings happen in 1 task rather
than multiple.

Sébastien Han 5bbbce527e osd: do not do anything if the dev has a partition
Regardless if the partition is 'ceph' or something else, we don't want
to be as strick as checking for a particular partition.
If the drive has a partition, we just don't do anything.

This solves the case where the server reboots, disks get a different
/dev/sda (node) allocation. In this case, prior to restarting the server
/dev/sda was an OSD, but now it's /dev/sdb and the other way around.
In such scenario, we will try to prepare the OSD and create a new
partition, so let's not mess around with devices that have partitions.

Guillaume Abrioux e537779bb3 osd: fix osd restart when dmcrypt
This commit fixes a bug that occurs especially for dmcrypt scenarios.

There is an issue where the 'disk_list' container can't reach the ceph
cluster because it's not launched with `--net=host`.

If this container can't reach the cluster, it will hang on this step
(when trying to retrieve the dm-crypt key) :

```
+common_functions.sh:448: open_encrypted_part(): ceph --cluster abc12 --name \
client.osd-lockbox.9138767f-7445-49e0-baad-35e19adca8bb --keyring \
/var/lib/ceph/osd-lockbox/9138767f-7445-49e0-baad-35e19adca8bb/keyring \
config-key get dm-crypt/osd/9138767f-7445-49e0-baad-35e19adca8bb/luks
+common_functions.sh:452: open_encrypted_part(): base64 -d
+common_functions.sh:452: open_encrypted_part(): cryptsetup --key-file \
-luksOpen /dev/sdb1 9138767f-7445-49e0-baad-35e19adca8bb
```

It means the `ceph-run-osd.sh` script won't be able to start the
`osd_disk_activate` process in ceph-container because he won't have
filled the `$DOCKER_ENV` environment variable properly.

Adding `--net=host` to the 'disk_list' container fixes this issue.

Guillaume Abrioux deaf273b25 syntax: change local_action syntax
Use a nicer syntax for `local_action` tasks.
We used to have oneliner like this:
```
local_action: wait_for port=22 host={{ hostvars[inventory_hostname]['ansible_default_ipv4']['address'] }} state=started delay=10 timeout=500 }}
```

The usual syntax:
```
    local_action:
      module: wait_for
      port: 22
      host: "{{ hostvars[inventory_hostname]['ansible_default_ipv4']['address'] }}"
      state: started
      delay: 10
      timeout: 500
```
is nicer and kind of way to keep consistency regarding the whole
playbook.

This also fix a potential issue about missing quotation :

writing `local_action: shell echo {{ fsid }} | tee {{ fetch_directory }}/ceph_cluster_uuid.conf`
can cause trouble because it's complaining with missing quotes, this fix solves this issue.

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

Sébastien Han bbc79765f3 osd: best effort if no device is found during activation
We have a scenario when we switch from non-container to containers. This
means we don't know anything about the ceph partitions associated to an
OSD. Normally in a containerized context we have files containing the
preparation sequence. From these files we can get the capabilities of
each OSD. As a last resort we use a ceph-disk call inside a dummy bash
container to discover the ceph journal on the current osd.

Christian Berendt 50a848dc40 Rename fact docker_version to ceph_docker_version
The name docker_version is very generic and is also used by other
roles. As a result, there may be name conflicts. To avoid this a
ceph_ prefix should be used for this fact. Since it is an internal
fact renaming is not a problem.

John Fulton 8cba44262c Add flags for OSD 'docker run --cpuset-{cpus,mems}'
Add the variables ceph_osd_docker_cpuset_cpus and
ceph_osd_docker_cpuset_mems, so that a user may specify
the CPUs and memory nodes of NUMA systems on which OSD
containers are run.

Provides a example in osds.yaml.sample to guide user
based on sample `lscpu` output since cpuset-mems refers
to the memory by NUMA node only while cpuset-cpus can
refer to individual vCPUs within a NUMA node.

This allows for easier debugging if verbosity is not set high enough.
