# OSD CRUSH LOCATION

# The following options will build a ceph.conf with OSD sections
# Example:
# [osd.X]
# osd crush location = "root=location"
#
# This works with your inventory file
# To match the following 'osd_crush_location' option the inventory must look like:
#
# [osds]
# osd0 ceph_crush_root=foo ceph_crush_rack=bar

crush_location: false

# Devices to be used as OSDs
# You can pre-provision disks that are not present yet.
# Ansible will just skip them. Newly added disk will be
# automatically configured during the next run.

# !! WARNING !!
#
# /!\ ENABLE ONLY ONE SCENARIO AT A TIME /!\
#
# !! WARNING !!

# Declare devices
# All the scenarii inherit from the following device declaration
#
#devices:
#  - /dev/sdb
#  - /dev/sdc
#  - /dev/sdd
#  - /dev/sde

# 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-disk. You should not be worried on using
# this option since ceph-disk has a built-in check which looks for empty devices.
# Thus devices with existing partition tables will not be used.
# This mode prevents you from filling out the 'devices' variable above.
#
#osd_auto_discovery: false

# I. First scenario: journal and osd_data on the same device
# Use 'true' to enable this scenario
# This will collocate both journal and data on the same disk
# creating a partition at the beginning of the device

#journal_collocation: false


# II. Second scenario: single journal device for N OSDs
# Use 'true' to enable this scenario

# deprecated, please use scenario III with a single raw_journal_device


# III. Third scenario: N journal devices for N OSDs
# Use 'true' to enable this scenario
#
# In the following example:
# * sdd and sde will get sdb as a journal
# * sdf and sdg will get sdc as a journal
# While starting you have 2 options:
# 1. Pre-allocate all the devices
# 2. Progressively add new devices

#raw_multi_journal: false
#raw_journal_devices:
#  - /dev/sdb
#  - /dev/sdb
#  - /dev/sdc
#  - /dev/sdc
#

# IV. Fourth scenario: use directory instead of disk for OSDs
# Use 'true' to enable this scenario

#osd_directory: false
#osd_directories:
#  - /var/lib/ceph/osd/mydir1
#  - /var/lib/ceph/osd/mydir2
#  - /var/lib/ceph/osd/mydir3
#  - /var/lib/ceph/osd/mydir4
