Mark.
I meant that the existing pools, this parameter is not used.
I'm sure he pools DATA, METADATA, RDB(They are created by default) have size = 3.

Hi.
This parameter does not apply to pools by default.
ceph osd dump | grep pool. see size=?

Der Irek：
Thanks for your reply.
Even already set "osd_pool_default_size = 2" the cluster still need
3 different hosts right？
Is this default number can be changed by user and write into
ceph.conf before deploy？
Best wishes,
Mika

Hi.
Because the disc requires three different hosts, the default
number of replications 3.

Hi all,
Try to use two OSDs to create a cluster. After the
deply finished, I found the health status is "88
active+degraded" "104 active+remapped". Before use 2 osds to
create cluster the result is ok. I'm confuse why this
situation happened. Do I need to set crush map to fix this
problem？
