Gracefully remove OSD¶
If you are using Rook Ceph Operator to run a Ceph Cluster in Kubernetes, please follow the official documentation here: Rook Docs - Ceph OSD Management.

(gracefully should always be used when the cluster is in use, though any OSD weight change will cause data redistribution)
