# By default, Ceph makes 2 replicas of objects. If you want to make three
|
|
# copies of an object the default value--a primary copy and two 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 = 1 # Allow writing one copy 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 = 3, we'd recommend approximately
|
|
# (100 * 10) / 3 = 333.
