CephOsdRemoveRequest#

The CephOsdRemoveRequest object is used for Ceph Object Storage Daemon (OSD) lifecycle management (LCM). It allows the operator to manage the removal of OSDs from the cluster.

Spec#

The spec section describes what should be cleaned up:

  • nodes: A mapping of node names with specifications:
    • completeCleanUp: Boolean flag for full node cleanup (including removal from the CRUSH map).
    • dropFromClusterOnly: Remove the OSD from the cluster without cleaning devices.
    • cleanupStrayPartitionsOnly: Clean only stray partitions.
    • cleanupByOsdId: List of OSD IDs to remove.
    • cleanupByDevice: List of devices to clean (by name or path).
  • Additional fields include approve, keepOnFail, resolved, resumeFailed, and resumeFailedStep.
