#'osd_auto_discovery' mode prevents you from filling out the 'devices' variable above.

# Device discovery is based on the Ansible fact 'ansible_devices'
|
|
# which reports all the devices on a system. If chosen, all the disks
|
|
# found will be passed to ceph-volume lvm batch. You should not be worried on using
|
|
# this option since ceph-volume has a built-in check which looks for empty devices.

# Use ceph-volume to create OSDs from logical volumes.

|
# lvm_volumes is a list of dictionaries.
|
|
#
|
|
# Filestore: Each dictionary must contain a data, journal and vg_name key. Any
|
|
# logical volume or logical group used must be a name and not a path. data
|
|
# can be a logical volume, device or partition. journal can be either a lv or partition.
|
|
# You can not use the same journal for many data lvs.
|
|
# data_vg must be the volume group name of the data lv, only applicable when data is an lv.
|
|
# journal_vg is optional and must be the volume group name of the journal lv, if applicable.
|
|
# For example:
|
|
# lvm_volumes:
|
|
# - data: data-lv1
|
|
# data_vg: vg1
|
|
# journal: journal-lv1
|
|
# journal_vg: vg2
|
|
# crush_device_class: foo
|
|
# - data: data-lv2
|
|
# journal: /dev/sda1
|
|
# data_vg: vg1
|
|
# - data: data-lv3
|
|
# journal: /dev/sdb1
|
|
# data_vg: vg2
|
|

# - data: /dev/sda1
|

# journal: /dev/sdb1
|
|
#
|
|
# Bluestore: Each dictionary must contain at least data. When defining wal or
|
|
# db, it must have both the lv name and vg group (db and wal are not required).
|
|
# This allows for four combinations: just data, data and wal, data and wal and
|
|
# db, data and db.
|
|
# For example:
|
|
# lvm_volumes:
|
|
# - data: data-lv1
|
|
# data_vg: vg1
|
|
# wal: wal-lv1
|
