Unable to make resize glusterfs pvc works

Open alvarosIGZ opened this issue 7 years ago • 5 comments

Hello, So I have v1.9.2 Kubernetes cluster with glusterfs. I've tried to implement this new Kubernetes feature with glusterfs https://kubernetes.io/docs/concepts/storage/persistent-volumes/#expanding-persistent-volumes-claims. Once I've set in kube-api YAML those two properties, I can deploy a SC with allowVolumeExpansion. I deploy a PVC with that SC and then I edit the PVC. No errors but the volume is not resized... Have you tested it works?

Best regards,

Sure, yeah I was talking to @alvarosIGZ and trying to figure out whats going wrong here. The current status is that, we have verified all the requirements which need to be met for resize has been done in this setup and also can see the resizer respond to certain requests. However we can not see heketi receiving the expansion requests. Need to figure out why its so.. will keep updating the status here.

also having the same issue, openshift 3.9 with glusterfs as a storageclass, set with allowVolumeExpansion. featuregates on masters/nodes set to allow this as well. pvc's resize, but disk does not.

resolved, apparently this is only supported by adding disks, and not expanding underlying disk
