|
|
#
|
|
# 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"

#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 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
|
|
#
|
|
#
|
|
# NOTE(leseb):
|
|
# On a containerized scenario we only support A SINGLE journal
|
|
# for all the OSDs on a given machine. If you don't, bad things will happen
|
|
# This is a limitation we plan to fix at some point.
|
|
#
|
|
#
|
|
# 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"

|
# 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"

#bluestore_wal_devices: "{{ dedicated_devices }}"

|
|
# III. Use ceph-volume to create OSDs from logical volumes.
|
|
# Use 'osd_scenario: lvm' to enable this scenario. Currently we only support dedicated journals
|
|
# when using lvm, not collocated journals.
|
|
# lvm_volumes is a dictionary whose key/value pair represent a data lv and a journal pair.
|
|
# Any logical volume or logical group used must be a name and not a path.
|
|
# Journals can be either a lv, device or partition. You can not use the same journal for many data lvs.
|
|
# For example:
|
|
# lvm_volumes:
|
|
# data-lv1: journal-lv1
|
|
# data-lv2: /dev/sda
|
|
# data:lv3: /dev/sdb1
|
|
#lvm_volumes: {}
