⚠️ Known issues​

  • When removing a node from a cluster, the node is successfully evicted but the OSDs associated with the removed node are not fully removed. Manual steps are required to properly remove the OSDs and release resources. (CubeCOS#101)

  • The installer might crash during installation. (CubeCOS#87)

  1. Reattempt login or installation process to restart and kick off installation.
  2. It may require multiple inputs before the installation process begins.
  • Rancher operations may encounter errors when upgrading to CubeCOS 3.0.0 from previous versions (requires AppFramework usage).
  1. Changes in the Cube node driver was made in v3.0.0 to better align with standard usage
  2. The Cube node driver address needs to be updated to reflect the new driver access address
  3. Navigate to Rancher management, enter Cluster Management -> Drivers -> Node Drivers -> Cube.
  4. Update the new Cube node driver URL to http://<cluster-vip>:8080/static/nodedrivers/docker-machine-driver-cube

  • Users may encounter errors when accessing the CubeCOS dashboard and the Ceph management dashboard simultaneously.

    • The CubeCOS dashboard and Ceph dashboard share a conflicting SAML token, which may result in loss of access when used concurrently.
    • Use incognito mode or separate browsers to avoid SAML token conflicts when accessing the CubeCOS and Ceph dashboards simultaneously.

  • Metrics in the Home → Health view may be temporarily unavailable during node failure or VIP migration. (CubeCOS#148)
