Create OpenStack pools with crush rule Add an extra variable to the openstack pools, which creates them with defined rules. This will allow to place different pools on e.g. different type of disks. This commit will also set a new default rule when defined and move the rbd pool to the new rule.

mon: fix osd_pool_default_crush_rule persistence and effectiveness Running the last portion (insert new default and add new default crush tasks) of crush_rules.yml only on the last monitor is wrong since ceph CLI calls usually end up on the master having the quorum, which is by default the one with the lower IP. So if we run the command and end up on another mon the creation will happen on the default crush rule because the particular mon hasn't been updated. To fix this we remove the |last on the include and use run_once: true on certain tasks, then we let the final two tasks run on all the monitors. Signed-off-by: Sébastien Han <seb@redhat.com>

Set the default crush rule in ceph.conf Currently the default crush rule value is added to the ceph config on the mon nodes as an extra configuration applied after the template generation via the ansible ini module. This implies two behaviors: 1/ On each ceph-ansible run, the ceph.conf will be regenerated via ceph-config+template and then ceph-mon+ini_file. This leads to a non necessary daemons restart. 2/ When other ceph daemons are collocated on the monitor nodes (like mgr or rgw), the default crush rule value will be erased by the ceph.conf template (mon -> mgr -> rgw). This patch adds the osd_pool_default_crush_rule config to the ceph template and only for the monitor nodes (like crush_rules.yml). The default crush rule id is read (if exist) from the current ceph configuration. The default configuration is -1 (ceph default).
