I'd like to upgrade some values in kubernetes cluster.

I am trying to update the values using values file (storageBackupCluster = 150 and storageRepo: 150Gi , circled in red in the picture below) with the next command:

helm upgrade cbur-master /<my_dir>/cbur*  --reset-values -f /<my_dir>/cbur-master.values --recreate-pods --home <my_dir>/helm_home --set storageBackupCluster=150Gi --set storageRepo=150Gi""

cbur-master.values

Persistent volume claims (pvc) are being update (120 to 150):

PVC

But inside the cluster file system , the size remain the same as before running the command (120 and not 150):

file system size

How can I also update the file system size?
