nf ceph osd
The nf ceph osd command creates a Ceph OSD (Object Storage Daemon) on a specific node and disk.
OSDs are where your data lives. Each OSD maps to a single physical disk. Ceph distributes data across OSDs using CRUSH rules to ensure redundancy and availability. For a production cluster, you’ll typically create one OSD per available disk on each worker node.
You can find available disks using nf disks list.
