Persistent Disk quota exceeded

[daniel_enaccess]

Hey community,

I started encountering 

Can’t create new resources when the  quota is exceeded  for any resources, such as CPU or Disk. 

in my GKE Cluster.

Looking further at my quotas I noticed: Persistent Disk SSD (GB) shows 415/500

Which surprises me. 

gcloud compute disks list

Shows 4 Disk, 3x 5GB (used in GKE) and 1x 10GB (used in GCE). I also went to check if there are any snapshots or backups taking space, but couldn't find any either.

My project setup is quite simple:

• 1x GKE Cluster in Autopilot mode with 2 namespaces
• 1x Compute Instance with 10GB disk

Running out of ideas on what to check here 🤔

Appreciate any help or hints on what else to check for.

Hi daniel_enaccess,

Welcome to Google Cloud Community!

When GKE Autopilot provisions a node, it also provisions a persistent disk for it. Those disks are different sizes  depending on the node machine: 100GB, 250GB etc.

To check the capacity of the Node use the following command: 

“Kubectl describe node <node name>”

You  can find it under the Capacity field. Here is the sample output below:
