 !!! warning

     Mounting large volumes may add considerable overhead to the application's start up time.
 
 
 Bellow there is an example of using a persistent volume claim with a Knative Service.
 
 ## Prerequisites

-    features:
-      "kubernetes.podspec-persistent-volume-claim": enabled
-      "kubernetes.podspec-persistent-volume-write": enabled

 * The `kubernetes.podspec-persistent-volume-claim` extension controls whether persistent volumes (PVs) can be used with Knative Serving.
 * The `kubernetes.podspec-persistent-volume-write` extension controls whether PVs are available to Knative Serving with the write access.
 
-> Note that if you have installed Serving via the Knative operator then you need to set the above feature flags at the corresponding Serving CR.
