说明
ceph is the command-line interface for managing Ceph distributed storage clusters. Ceph provides unified object, block, and file storage with automatic data replication, self-healing, and no single point of failure. The command communicates with the Ceph monitor daemons to perform cluster administration tasks including checking health status, managing OSDs (Object Storage Daemons), configuring placement groups, and handling authentication. It serves as the primary tool for day-to-day cluster operations and troubleshooting. Ceph organizes data into pools, which contain placement groups that map to OSDs across the cluster. The `ceph status` command provides a quick overview of cluster health, while more specific subcommands allow fine-grained control over individual components.
