Increase Kasten Catalog Storage

You may notice that Kasten indicated less than 50% on catalog storage. Less than 50% storage will not allow you to perform further Kasten upgrades. 

The first thing that you need to do is add more storage on the worker node & expand it.

If the problem still persists, then you need to increase the default catalog pv size from 20Gi to 40Gi.

Before you do that, you need to check and make sure your storage class allows you to do so.


kubectl get storageclass <storageclass> -o jsonpath={'.allowVolumeExpansion'}
Note:- take note of the dot inside the { }
The result must be "true"

Next steap
Run a helm upgrade to increase global.persistence.catalog.size to your desired value (example below sets to 40GB):

helm get values k10 --output yaml --namespace=kasten-io > k10_val.yaml && \
   helm upgrade k10 kasten/k10 --namespace=kasten-io -f k10_val.yaml \
   --set global.persistence.catalog.size=40Gi

You storageclass pv has increased to 40Gi
