Guillaume Abrioux 6130bc841d config: look up for monitor_address_block in hostvars
`monitor_address_block` should be read from hostvars[host] instead of
current node being played.

eg:

Let's assume we have:

```
[mons]
ceph-mon0 monitor_address=192.168.1.10
ceph-mon1 monitor_interface=eth1
ceph-mon2 monitor_address_block=192.168.1.0/24
```

the ceph.conf generation task will end up with:

```
fatal: [ceph-mon0]: FAILED! => {}

MSG:

'ansible.vars.hostvars.HostVarsVars object' has no attribute u'ansible_interface'
```

the reason is that it will assume `monitor_address_block` isn't defined even on
ceph-mon2 because looking for `monitor_address_block` instead of
`hostvars[host]['monitor_address_block']`, therefore it enters in the condition as default value:

```
    {%- else -%}
      {% set interface = 'ansible_' + (monitor_interface | replace('-', '_')) %}
      {% if ip_version == 'ipv4' -%}
        {{ hostvars[host][interface][ip_version]['address'] }}
      {%- elif ip_version == 'ipv6' -%}
        [{{ hostvars[host][interface][ip_version][0]['address'] }}]
      {%- endif %}
    {%- endif %}
```

`monitor_interface` is set with default value `'interface'` so the `interface`
variable is built with 'ansible_' + 'interface'. It makes ansible throwing a
confusing message about `'ansible_interface'`.

Guillaume Abrioux 144c92b21f purge: actually remove of /var/lib/ceph/*
38dc20e74b introduced a bug in the purge
playbooks because using `*` in `command` module doesn't work.

`/var/lib/ceph/*` files are not purged it means there is a leftover.

detecting existing keyring, therefore, it assumed a cluster already
existed.

Matthew Vernon 04f4991648 restart_osd_daemon.sh.j2 - consider active+clean+* pgs as OK
After restarting each OSD, restart_osd_daemon.sh checks that the
cluster is in a good state before moving on to the next one. One of
the checks it does is that the number of pgs in the state
"active+clean" is equal to the total number of pgs in the cluster.

On large clusters (e.g. we have 173,696 pgs), it is likely that at
least one pg will be scrubbing and/or deep-scrubbing at any one
time. These pgs are in state "active+clean+scrubbing" or
"active+clean+scrubbing+deep", so the script was erroneously not
including them in the "good" count. Similar concerns apply to
"active+clean+snaptrim" and "active+clean+snaptrim_wait".

Fix this by considering as good any pg whose state contains
active+clean. Do this as an integer comparison to num_pgs in pgmap.

(could this be backported to at least stable-3.0 please?)

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.
