Description of problem: currently when using osd_scenario=lvm, users must manually create logical volumes prior to running ceph-ansible for deployment. for RHCS 3.2 ceph-volume should handle creation of LVs for both bluestore and filestore deployments Additional Info: addressed for filestore in RHCS 3.1 by this ad-hoc playbook bz 1591074 https://bugzilla.redhat.com/show_bug.cgi?id=1591074
This is already in ceph-ansible master: http://docs.ceph.com/ceph-ansible/master/osds/scenarios.html#lvm It will require backporting the ceph-volume functionality that currently exists in ceph master back to luminous

That is a documentation bug in ceph-ansible, it is no longer accurate
John could you please clarify if you are looking for bucket index creations or for LVs for OSDs? In current master of both ceph-ansible and Ceph, we handle the creation of LVs from an input of devices *to create OSDs* We do not handle anything for bucket indexes as mentioned in the linked BZ that ended in an ad-hoc ceph-ansible playbook
Alfredo, what should the changes to osd.yml look something like? Something like this: osd_objectstore: bluestore osd_scenario: lvm devices: - /dev/sdb - /dev/sdc - ...

@sagrawal before these changes, it was required that logical volumes be pre-created for ceph-ansible to pass them onto ceph-volume. These changes allow one to simply use `devices` and the logical volumes will be created (see http://docs.ceph.com/ceph-ansible/master/osds/scenarios.html#lvm ) For example: osd_scenario: lvm devices: - /dev/sda - /dev/sdb
