1、Adding osds in same one failure domain is to ensure only one PG in pg up set (ceph pg dump shows)to remap. 2、Setting "osd_pool_default_min_size=1" is to ensure objects to read/write uninterruptedly while pg remap. Is this wrong?

Den tors 25 juli 2019 kl 04:36 skrev zhanrzh...@teamsun.com.cn <zhanrzh...@teamsun.com.cn>: I think it should to set "osd_pool_default_min_size=1" before you add osd , and the osd that you add at a time should in same Failure domain. That sounds like weird or even bad advice? What is the motivation behind it? -- May the most significant bit of your life be positive.
