Problem/Question
When deploying the helm chart, it seems its not possible to reuse existing PV’s and PVC’s. I dumped the helm values with helm show values netdata/netdata > default-values.yaml and all I see is this part:
persistence:
enabled: true
## Set '-' as the storageclass to get a volume from the default storage class.
storageclass: "-"
volumesize: 1Gi
Relevant docs you followed/actions you took to solve the issue
Environment/Browser/Agent’s version etc
Irrelevant
What I expected to happen
Many (still not enough 
) Helm charts allow to reuse an already existing PVC. Use cases would include:
- storage providers that generate random and incomprehensible names but allow sensible names to be created manually
- storage providers that create fixed volume sizes unable to resize by default but allow resizable volumes to be created manually
- Storage providers that can create backups of volumes, but are unable to restore to new / existing volumes and only restore the exact volume with its original volume name.
Longhorn for example, is one such storage provider.
These are just a few examples of why it is really handy to allow the use of existing claims.
