# 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:
2014-09-05 03:14:11 +08:00
#
# [osds]
# osd0 ceph_crush_root=foo ceph_crush_rack=bar
crush_location: false

# This will collocate both journal and data on the same disk

# 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
