I have a cluster on GKE with many pods and persistent disks (PD) and cannot deploy anymore.
pod failed to fit in any node fit failure on node (XX): MaxVolumeCount
The issue should not affect me because I have a 2-code machine and Google recently raised the persistent disk limit to 64:
The problems seems to be a env var in the master that says KUBE_MAX_PD_VOLS = 16
. The issue seems to be fixed but since I have a hosted master I cannot find the way to change the env var.

So the question is:
How can I change an env var in a GKE master?
