Hi , is PV size grow feature still in alpha in master now? How do I open this feature, set in kubelet, kube-apiserer and kube-controller-manager config?
I have figured out that should be set in kubelet, kube-apiserer, kube-controller-manager, kube-scheduler config, and also need to enable in apiserver admission control. It works well.
should we go ahead and close this issue?
also file needs to be updated to allow resizing. This plugin provides additional checks for resizing.
For azure disk, there is blocking issue: it does not support disk resize on a Running VM. I would suggest work on first, could you review , it works well in my testing env.

Awww shucks, looks like I don't have magic powers. please close this when you have a chance?
has been merged, while for azure disk work is just in investigation state mainly because there is blocking issue: it does not support disk resize on a Running VM.
could someone move this issue out of milestone v1.10, thanks.

Why was this closed? This is not fixed by that crappy PR. This is the kubernetes repo, and this refers to k8s apis being implemented correctly iyam. The PR that you closed this with does NOT support disk resize on a Running VM. Your words Please reopen this.
pls track this issue for online resize feature:
