Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!
Starting with MOSK 25.2, the MOSK documentation set will cover all product layers, including MOSK management (formerly MCC). This means everything you need will be in one place. The separate MCC documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.
High-level workflow of Ceph OSD or node removal¶
The Ceph LCM automated operations such as Ceph OSD or Ceph node removal are
performed by creating a corresponding KaaSCephOperationRequest
CR that
creates separate CephOsdRemoveRequest
requests. It allows for automated
removal of healthy or non-healthy Ceph OSDs from a Ceph cluster and covers the
following scenarios:
Reducing hardware - all Ceph OSDs are up/in but you want to decrease the number of Ceph OSDs by reducing the number of disks or hosts.
Hardware issues. For example, if a host unexpectedly goes down and will not be restored, or if a disk on a host goes down and requires replacement.
This section describes the KaaSCephOperationRequest
CR creation workflow,
specification, and request status.
For step-by-step procedures, refer to Automated Ceph LCM.
