About MSDP Scaleout status and events

The MSDP Scaleout CR status includes the readiness state, the storage space utilization (via PersistentVolumeClaim) of each Controller, MDS, and Engine pod.

In the initial configuration of MSDP Scaleout, the readiness state of each pod changes from "false" to "true" in the first few minutes. When the state of all the pods changes to "true", it indicates MSDP Scaleout is ready for use.

You can check the storage space utilization routinely to plan MSDP Scaleout autoscaling before the storage space runs out.

Example of the of the status format:

kubectl -n sample-cr-namespace get msdpscaleout sample-cr -o json
