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

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？[global]
