Monitors receives state information from other components to maintain maps and circulate these maps to other Monitor and OSD nodes. # Ceph MON ( Monitors ) maintains overall health of cluster by keeping cluster map state including Monitor map, OSD map, Placement Group ( PG ) map, and CRUSH map. Its recommended to user 1 OSD per physical disk. # Ceph OSD ( Object Storage Daemons ) storage data in objects, manages data replication, recovery, rebalancing and provides stage information to Ceph Monitor. Didn’t Read / TLDR (Basics concepts in Ceph) Ceph Components: Recommended reading: Zero To Hero Guide : : For CEPH CLUSTER PLANNING Too Long. It is recommended to read some documents to understand basics about ceph before starting, though following this guide, we should end up with a working ceph storage cluster even if we have no idea what is ceph. Note: The demonstrated setup is not the best practices but rather a demonstration of how we can quickly setup the ceph cluster on PVE cluster and test it. We want to test/get an feeling of ceph storage on Proxmox VE (PVE) quickly The Answer
