Replace a failed Ceph OSD with a metadata device

The document describes various scenarios of a Ceph OSD outage and recovery or replacement. More specifically, this section describes how to replace a failed Ceph OSD with a metadata device:

• If the metadata device is specified as a logical volume in the BareMetalHostProfile object and defined in the KaaSCephCluster object as a logical volume path

• If the metadata device is specified in the KaaSCephCluster object as a device name

Note

Ceph OSD replacement implies the usage of the KaaSCephOperationRequest custom resource (CR). For workflow overview, spec and phases description, see High-level workflow of Ceph OSD or node removal.
