Is there a simple way to get the current attached volume state (think "space left on disk", or the opposite) ? Using stackdriver, this info is not provided. Not to be found neither within the gcloud console. I was wondering if this was accessible besides connecting to the instance and check it manually

With "instance" do you mean the node in the kubernetes cluster or of the persistent volume attached? – GalloCedrone Feb 06 '18 at 09:33

The persistent volume yes – Ben Feb 06 '18 at 10:01

Am wondering how to make the title more accurate; thought naming pvc first would imply it – Ben Feb 06 '18 at 12:04

Check Prometeus.
At the moment this option is available through Kubernetes, but merely for the 1.8 version on. As you can check here there is a whole topic regarding this feature request and the code that implement these features.
Kubernetes 1.8 expose metrics for prometheus.
- kubelet_volume_stats_available_bytes
- kubelet_volume_stats_capacity_bytes
- kubelet_volume_stats_inodes
- kubelet_volume_stats_inodes_free
- kubelet_volume_stats_inodes_used
- kubelet_volume_stats_used_bytes
