Hi @willes, please see this doc that describes how you can specify your storage class in the yaml manifest: https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-volume-claim-templates.html.

yes , but i can't understand what it is , It's not a complete yaml file , i don't know what it tell me , what i should create or what i shoud change, there already have a pending pvc ,how can i Handle it?

5

should i change the already running statefulset yaml at the pvc option?

kubectl edit sts quickstart-es-default

but it furbid me to save it .

or should i create a new pvc and pv?

6

i find the pvc define , but there have no storageclass name

kubectl get sts quickstart-es-default -o yaml
