Hi,
I am using glusterfs as storage.
Here is my storage class:
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: standard
provisioner: kubernetes.io/glusterfs
parameters:
resturl: "http://192.168.198.135:8080"
restauthenabled: "false"
restuser: "notusedyet"
restuserkey: "notusedyet"
volumetype: replicate:2
allowVolumeExpansion: true
I created a pvc of 10Gi, but I am not using much of it. So I wanted to shrink it. If I update the pvc I get following error:
The PersistentVolumeClaim "poc-redis" is invalid: spec.resources.requests.storage: Forbidden: field can not be less than previous value
So what options do I have to shrink this volume? Are there any ways with or without downtime are available? (better without downtime)
In worst case: is there a way to clone a volume to a new one which is smaller?
Thanks, Andreas
