WebThe Ceph Storage Cluster is the foundation for all Ceph deployments. Based upon RADOS, Ceph Storage Clusters consist of several types of daemons: a Ceph OSD Daemon (OSD) stores data as objects on a storage node. a Ceph Monitor (MON) maintains a master copy of the cluster map. A Ceph Storage Cluster might contain thousands of storage nodes.

WebPlacement groups (PGs) are an internal implementation detail of how Ceph distributes data. You may enable pg-autoscaling to allow the cluster to make recommendations or automatically adjust the numbers of PGs ( pgp_num ) for each pool based on expected cluster and pool utilization. WebThese upmap entries provide fine-grained control over the PG mapping. This CRUSH mode will optimize the placement of individual PGs in order to achieve a balanced distribution. In most cases, this distribution is “perfect,” which an equal number of PGs on each OSD (+/-1 PG, since they might not divide evenly).
