Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!

Starting with MOSK 25.2, the MOSK documentation set covers all product layers, including MOSK management (formerly Container Cloud). This means everything you need is in one place. Some legacy names may remain in the code and documentation and will be updated in future releases. The separate Container Cloud documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

The ceph-exporter pods are present in the Ceph crash list

Warning

This procedure is valid for MOSK clusters that use the deprecated KaaSCephCluster custom resource (CR) instead of the MiraCeph CR that is available since MOSK 25.2 as a new Ceph configuration entrypoint. For the equivalent procedure with the MiraCeph CR, refer to the following section:

The ceph-exporter pods are present in the Ceph crash list

After a MOSK cluster update, the ceph-exporter pods may be present in the ceph crash ls or ceph health detail list while rook-ceph-exporter attempts to obtain the port that is still in use. For example:

ceph health detail

HEALTH_WARN 1 daemons have recently crashed
[WRN] RECENT_CRASH: 1 daemons have recently crashed
    client.ceph-exporter crashed on host kaas-node-b59f5e63-2bfd-43aa-bc80-42116d71188c at 2024-10-01T16:43:31.311563Z

The issue does not block the MOSK cluster update. Once the port becomes available, rook-ceph-exporter obtains the port and the issue disappears.

To apply the issue resolution, run ceph crash archive-all to remove ceph-exporter pods from the Ceph crash list.
