#'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-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.

# Encrypt your OSD device using dmcrypt

|
|
|
# I. First scenario: collocated
|
|
#
|
|
# To enable this scenario do: osd_scenario: collocated
|
|
#
|
|
#
|
|
# If osd_objectstore: filestore is enabled both 'ceph data' and 'ceph journal' partitions
|
|
# will be stored on the same device.
|
|
#
|
|
# If osd_objectstore: bluestore is enabled 'ceph data', 'ceph block', 'ceph block.db', 'ceph block.wal' will be stored
|
|
# on the same device. The device will get 2 partitions:
|
|
# - One for 'data', called 'ceph data'
|
|
# - One for 'ceph block', 'ceph block.db', 'ceph block.wal' called 'ceph block'
|
|
#
|
|
# Example of what you will get:
|
|
# [root@ceph-osd0 ~]# blkid /dev/sda*
|
|
# /dev/sda: PTTYPE="gpt"
|
|
# /dev/sda1: UUID="9c43e346-dd6e-431f-92d8-cbed4ccb25f6" TYPE="xfs" PARTLABEL="ceph data" PARTUUID="749c71c9-ed8f-4930-82a7-a48a3bcdb1c7"
|
|
# /dev/sda2: PARTLABEL="ceph block" PARTUUID="e6ca3e1d-4702-4569-abfa-e285de328e9d"

#

# Note: This scenario uses the ceph-disk tool to provision OSDs

|
|
#osd_scenario: dummy
|
|
#valid_osd_scenarios:
|
|
# - collocated
|
|
# - non-collocated
|
|
# - lvm
|
|
|
|
|
|
# II. Second scenario: non-collocated
|
|
#
|
|
# To enable this scenario do: osd_scenario: non-collocated
|
|
#
|
|
# If osd_objectstore: filestore is enabled 'ceph data' and 'ceph journal' partitions
|
|
# will be stored on different devices:
|
|
# - 'ceph data' will be stored on the device listed in 'devices'
|
|
# - 'ceph journal' will be stored on the device listed in 'dedicated_devices'
|
|
#
|
|
# Let's take an example, imagine 'devices' was declared like this:
|
|
#
|
|
# devices:
|
|
# - /dev/sda
|
|
# - /dev/sdb
|
|
# - /dev/sdc
|
|
# - /dev/sdd
|
|
#
|
|
# And 'dedicated_devices' was declared like this:
|
|
#
|
|
# dedicated_devices:
|
|
# - /dev/sdf
|
|
# - /dev/sdf
|
|
# - /dev/sdg
|
|
# - /dev/sdg
|
|
#
|
|
# This will result in the following mapping:
|
|
# - /dev/sda will have /dev/sdf1 as a journal
|
|
# - /dev/sdb will have /dev/sdf2 as a journal
|
|
# - /dev/sdc will have /dev/sdg1 as a journal
|
|
# - /dev/sdd will have /dev/sdg2 as a journal
|
|
#
|
|
#
|
|
# If osd_objectstore: bluestore is enabled, both 'ceph block.db' and 'ceph block.wal' partitions will be stored
|
|
# on a dedicated device.
|
|
#
|
|
# So the following will happen:
|
|
# - The devices listed in 'devices' will get 2 partitions, one for 'block' and one for 'data'.
|
|
# 'data' is only 100MB big and do not store any of your data, it's just a bunch of Ceph metadata.
|
|
# 'block' will store all your actual data.
|
|
# - The devices in 'dedicated_devices' will get 1 partition for RocksDB DB, called 'block.db'
|
|
# and one for RocksDB WAL, called 'block.wal'
|
|
#
|
|
# By default dedicated_devices will represent block.db
|
|
#
|
|
# Example of what you will get:
|
|
# [root@ceph-osd0 ~]# blkid /dev/sd*
|
|
# /dev/sda: PTTYPE="gpt"
|
|
# /dev/sda1: UUID="c6821801-2f21-4980-add0-b7fc8bd424d5" TYPE="xfs" PARTLABEL="ceph data" PARTUUID="f2cc6fa8-5b41-4428-8d3f-6187453464d0"

# /dev/sda2: PARTLABEL="ceph block" PARTUUID="ea454807-983a-4cf2-899e-b2680643bc1c"

|

|
|
#dedicated_devices: []
|
|
|
|
|
|
# More device granularity for Bluestore
|
|
#
|
|
# ONLY if osd_objectstore: bluestore is enabled.
|
|
#
|
|
# By default, if 'bluestore_wal_devices' is empty, it will get the content of 'dedicated_devices'.
|
|
# If set, then you will have a dedicated partition on a specific device for block.wal.
|
|
#
|
|
# Example of what you will get:
|
|
# [root@ceph-osd0 ~]# blkid /dev/sd*
|
|
# /dev/sda: PTTYPE="gpt"
|
|
# /dev/sda1: UUID="39241ae9-d119-4335-96b3-0898da8f45ce" TYPE="xfs" PARTLABEL="ceph data" PARTUUID="961e7313-bdb7-49e7-9ae7-077d65c4c669"
|
|
# /dev/sda2: PARTLABEL="ceph block" PARTUUID="bff8e54e-b780-4ece-aa16-3b2f2b8eb699"
|
|
# /dev/sdb: PTTYPE="gpt"
|
|
# /dev/sdb1: PARTLABEL="ceph block.db" PARTUUID="0734f6b6-cc94-49e9-93de-ba7e1d5b79e3"
|
|
# /dev/sdc: PTTYPE="gpt"
|
|
# /dev/sdc1: PARTLABEL="ceph block.wal" PARTUUID="824b84ba-6777-4272-bbbd-bfe2a25cecf3"
|

# Note: This option uses the ceph-disk tool
|
|
#bluestore_wal_devices: "{{ dedicated_devices }}"
|
|
|
|
# III. Use ceph-volume to create OSDs from logical volumes.
|
|
# Use 'osd_scenario: lvm' to enable this scenario.
|
|
# when using lvm, not collocated journals.
|
|
# 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/sda
|
|
# journal: /dev/sdb1
|
|
# - 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
|
|
# wal_vg: vg1
|
|
# crush_device_class: foo
|
|
# - data: data-lv2
|
|
# db: db-lv2
|
|
# db_vg: vg2
|
|
# - data: data-lv3
|
|
# wal: wal-lv1
|
|
# wal_vg: vg3
|
|
# db: db-lv3
|
|
# db_vg: vg3
|
|
# - data: data-lv4
|
|
# data_vg: vg4
|
|
# - data: /dev/sda
|
|
# - data: /dev/sdb1
|
|
|
|
#lvm_volumes: []
|
|
#crush_device_class: ""
|
|
#osds_per_device: 1
