Neha Ojha 27027a17d3 osd: add osd memory target option
BlueStore's cache is sized conservatively by default, so that it does
not overwhelm under-provisioned servers. The default is 1G for HDD, and
3G for SSD.

To replace the page cache, as much memory as possible should be given to
BlueStore. This is required for good performance. Since ceph-ansible
knows how much memory a host has, it can set

`bluestore cache size = max(total host memory / num OSDs on this host * safety
factor, 1G)`

Due to fragmentation and other memory use not included in bluestore's
cache, a safety factor of 0.5 for dedicated nodes and 0.2 for
hyperconverged nodes is recommended.

Sébastien Han 6d7fa99ff7 defaults: fix rgw_hostname
A couple if things were wrong in the initial commit:

* ceph_release_num[ceph_release] >= ceph_release_num['luminous'] will
never work since the ceph_release fact is set in the roles after. So
either ceph-common or ceph-docker-common set it

* we can easily re-use the initial command to check if a cluster is
running, it's more elegant than running it twice.

* set the fact rgw_hostname on rgw nodes only

Markos Chandras 126e2e3f92 roles: ceph-defaults: Check if 'rgw' attribute exists for rgw_hostname
If there are no services on the cluster, then the 'rgw' could be missing
and the task is failing with the following problem:

msg": "The task includes an option with an undefined variable.
The error was: 'dict object' has no attribute 'rgw'

We fix this by checking the existence of the 'rgw' attribute. If it's

Markos Chandras 37e50114de roles: ceph-defaults: Delegate cluster information task to monitor node
Since commit f422efb1d6 ("config: ensure
rgw section has the correct name") we observe the following failures in
new Ceph deployment with OpenStack-Ansible

fatal: [aio1_ceph-rgw_container-fc588f0a]: FAILED! => {"changed": false,
"cmd": "ceph --cluster ceph -s -f json", "msg": "[Errno 2] No such file

This is because the task executes 'ceph' but at this point no package
installation has happened. Packages are normally installed in the
'ceph-common' role which runs after the 'ceph-defaults' one.

Since we are looking to obtain cluster information, the task should be
delegated to a monitor node similar to other tasks in that role

Guillaume Abrioux c68126d6fd mdss: do not make pg_num a mandatory params
When playing ceph-mds role, mon nodes have set a fact with the default
pg num for osd pools, we can simply default to this value for cephfs
pools (`cephfs_pools` variable).

At the moment the variable definition for `cephfs_pools` looks like:

```
cephfs_pools:
  - { name: "{{ cephfs_data }}", pgs: "" }
  - { name: "{{ cephfs_metadata }}", pgs: "" }
```

and we have a task in `ceph-validate` to ensure `pgs` has been set to a
valid value.

We could simply avoid this check by setting the default value of `pgs`
to `hostvars[groups[mon_group_name][0]]['osd_pool_default_pg_num']` and
let to users the possibility to override this value.

Subhachandra Chandra c7e269fcf5 Fix restarting OSDs twice during a rolling update.
During a rolling update, OSDs are restarted twice currently. Once, by the
handler in roles/ceph-defaults/handlers/main.yml and a second time by tasks
in the rolling_update playbook. This change turns off restarts by the handler.
Further, the restart initiated by the rolling_update playbook is more
efficient as it restarts all the OSDs on a host as one operation and waits
for them to rejoin the cluster. The restart task in the handler restarts one
OSD at a time and waits for it to join the cluster.
