# By default, Ceph makes 3 replicas of RADOS objects. If you want to maintain four
# copies of an object the default value--a primary copy and three replica
# copies--reset the default values as shown in 'osd_pool_default_size'.
# If you want to allow Ceph to write a lesser number of copies in a degraded
# state, set 'osd_pool_default_min_size' to a number less than the
# 'osd_pool_default_size' value.
osd_pool_default_size = 3 # Write an object 3 times.
osd_pool_default_min_size = 2 # Allow writing two copies in a degraded state.
# Ensure you have a realistic number of placement groups. We recommend
# approximately 100 per OSD. E.g., total number of OSDs multiplied by 100
# divided by the number of replicas (i.e., osd pool default size). So for
# 10 OSDs and osd pool default size = 4, we'd recommend approximately
# (100 * 10) / 4 = 250.
# always use the nearest power of 2
osd_pool_default_pg_num = 256
