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?
