Hello Cephers, I use ceph-ansible v3.1.5 to build a new Mimic CEph Cluster for OpenStack. I want to use Erasure Coding for certain pools (images, cinder backups, cinder for one additional backend, rgw data...). The examples in group_vars/all.yml.sample don't show how to specify an erasure coded pool. I know I have to create two pool one little replicated one and an EC one used as default datapool for specific Ceph users. Does someone has an example to create such a pool ? Here is the definition of a replicated pool : openstack_cinder_backup_pool: name: "backups" pg_num: "8" pgp_num: "16" rule_name: "replicated_rule" type: 1 erasure_profile: "" expected_num_objects: "" application: "rbd" What is that type number ? I tried to read the Ansible role here : roles/ceph-osd/tasks/ openstack_config.yml But quiet hard to read / understand (always wonder what is that type thing I can't find in the docs : http://docs.ceph.com/docs/mimic/rados/operations/ pools/): - name: create openstack pool(s) command: > {{ hostvars[groups[mon_group_name][0]]['docker_exec_cmd'] | default('') }} ceph --cluster {{ cluster }} osd pool create {{ item.0.name }} {{ item.0.pg_num }} {{ item.0.pgp_num | default(item.0.pg_num) }} {{ rule_name if item.0.rule_name | default(rule_name) == '' else item. 0.rule_name | default(rule_name) }} {{ 1 if item.0.type|default(1) == 'replicated' else 3 if item.0.type| default(1) == 'erasure' else item.0.type|default(1) }} {%- if (item.0.type | default("1") == '3' or item.0.type | default("1") == 'erasure') and item.0.erasure_profile != '' %} {{ item.0.erasure_profile }} {%- endif %} {{ item.0.expected_num_objects | default('') }} _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
