Google Cloud - GKE cluster creation failures

I can’t create a GKE cluster with existing resources.

Insufficient regional quota to satisfy request: resource “DISKS_TOTAL_GB”: request requires ‘100.0’ and is short ‘50.0’. project has a quota of ‘50.0’ with ‘50.0’ available. View and manage quotas at https://console.cloud.google.com/iam-admin/quotas?usage=USED&project=clgcporg8-021.

Its described here Insufficient regional quota - #4 by Tej-Singh-Rana. I managed to solve it by changing quota to 15G/machine.
