Briefly, PGs = round2((Total_number_of_OSD * 100) / max_replication_count). Shrinking a cluster is not supported by Console, but we need to provide a way to remove nodes from the cluster at least on the CLI. 在 OSD 挂掉 5分钟 ( mon_osd_down_out_interval = 300 )之后,这个 OSD 会被标记为 out 状态,可以理解为 Ceph 认为这个 OSD 已经不属于集群了,然后就会把 PG 0. Raises according to the status reported by the Ceph cluster. Monitor maintains health of entire cluster , it contains PG logs and OSD logs. py $osdthatcrashes $outputfolder: options:. You need to set both the number of placement groups (total), and the number of placement groups used for objects (used in PG splitting). Ceph is a distributed object, block, and file storage platform - ceph/ceph Set the default budget based on the current defaults: 3000 per osd, and a rule of thumb target of 100 PGs per OSD. 这里只在主osd上创建pg, 如果不是主,就跳出循环,不在该osd上创建。其实会由其他的osd来创建。 g. Ceph: properly remove an OSD Sometimes removing OSD, if not done properly can result in double rebalancing.
