.New subcommand: `ceph-volume lvm batch'
This update adds the `ceph-volume lvm batch` subcommand that allows creation of volume groups and logical volumes for OSD provisioning from raw disks. The `batch` subcommand makes creating logical volumes easier for users who are not familiar with the Logical Volume Manager (LVM). With `batch`, one or many OSDs can be created by passing an array of devices and an OSD count per device to the `ceph-volume lvm batch` command.

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

I see this in the URL you provided > Note > > The creation of the logical volumes is not supported by ceph-ansible, > ceph-volume only creates OSDs from existing logical volumes. 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 - ... *** Bug 1631729 has been marked as a duplicate of this bug. *** @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 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
