Cube Cloud Management Portal (CubeCMP)

Rancher is known for its capability to manage kubernetes clusters, be they on public platforms such as GKE, EKS, AKS or Rancher’s offering, RKE. Additional project concepts, role based access controls, monitoring and logging are there to group and make concrete administrative tasks for each cluster. The idea is taken another step further to provide an app store-like space, Apps, where k8s applications that are readily-made can be added to this space via managing catalogs settings.

One long pending issue clients reported was the slow overall recovery time for Ceph clusters to be back at HEALTH_OK status. Depending on the actual hardware and setups (mainly the number of disks), this duration was reported to vary from one to multiple hours when there were power failures or planned maintenance. We’ve acknowledged this ticket and were able to reproduce it. After some observations, we could conclude that an action as simple as restarting ceph-osd (Object Storage Daemon) could lead to such a long recovery process.
