# when creating a pool.
# Optional. Integer. Default provided by Ceph.
#
# [*osd_crush_update_on_start*] The default OSDs behaviour on start when
# it comes to registering their location in the CRUSH map.
# Optional. Boolean. Defaults to undef.
#
# [*mon_osd_full_ratio*] Percentage of disk space used before
# an OSD considered full
# Optional. Integer e.g. 95, NOTE: ends in config as .95

# Optional. Default provided by Ceph
#
# [*osd_op_threads*] The number of threads to service Ceph OSD Daemon operations.
