been bashing its head against a wall trying to figure out why the cephfs csi provisoner isn't doing anything when it creates a pvc tied to the cephfs storageclass

@thermia Nevermind, volumeBindingMode defaults to Immediate and ceph-csi-cephfs's StorageClass doesn't override that (https://github.com/ceph/ceph-csi/blob/v3.18.1/charts/ceph-csi-cephfs/templates/storageclass.yaml).. hm

1. Reads two numbers kubelet already exports for every mounted volume:

kubelet_volume_stats_used_bytes / kubelet_volume_stats_capacity_bytes

then joins kube_persistentvolumeclaim_info with group_left. kubelet knows usage; only kube-state-metrics knows the storageclass and PV.

Careful crediting the 200 GB to helm uninstall — it leaves PVCs alone by default unless the chart sets helm.sh/resource-policy: delete. More likely your StatefulSet PVCs were dynamically provisioned on a StorageClass with reclaimPolicy: Delete, and the volumes went away with the pods. Worth …

How it decides: every loop it reads kubelet_volume_stats_* from Prometheus. Free space under the threshold (default 10%) and the PVC request grows by the increase (default 10%), rounded up to a GiB.

Opt-in twice: an annotation on the StorageClass, a storage_limit on the PVC.

Bind-mount hardening is the right fix for hostPath-style escapes. For CSI/NAS volumes the same exposure hides one layer down, in the StorageClass - Trident exposes NFS mount options and export policies per backend, and those outlive any pod-level change.

I am fed up with all the kubernetes DSL. helm and kustomize may do the work, but I need to learn a lot to do my job. E.g. a task as simple as copy and modify existing StorageClass to support Retain ReclaimPolicy is not easily achievable to me. I need to learn a ton of the syntax and semantics.

2/3 This storage account will be accessible from the Internet, even if the cluster is private and running in a private vnet.

To parameterize the storage account creation and e.g. prevent the account from being accessible via the Internet, you must use a custom StorageClass.

Андрій Головін ділиться практичним гайдом для тих, хто розробляє під Kubernetes, але не має доступу до хмари. У статті він детально розглянув, як розгорнути локальний кластер за допомогою Kind, змонтувати файлову систему хосту як Persistent Volume і налаштувати StorageClass для збереження даних за межами життєвого циклу подів.

My least favorite k8s abstraction (from my time at MariaDB before they spun off SkySQL) was that a physical volume claim (pvc) uses StorageClass to determine how many iops are requested in EBS physical volumes (pv).

[kubernetes] CVE-2025-13281: Portworx Half-Blind SSRF in kube-controller-manager
oss-sec: [kubernetes] CVE-2025-13281: Portworx Half-Blind SSRF in kube-controller-manager
Posted by Nathan Herz on Dec 01 Hello Kubernetes Community, A half-blind Server Side Request Forgery (SSRF) vulnerability exists in kube-controller-manager when using the in-tree Portworx StorageClass. This vulnerability allows authorized users to leak arbitrary information from unprotected endpoints in the control plane’s host network (including link-local or loopback services). The in-tree Portworx StorageClass has been disabled by default starting in version v1.31 from...

Afaik this might happen if you have no storageClass defined in the values.
If that's not the issue can you share the error msg ?

Bon donc, j'ai foiré mon déploiement Rook : j'ai oublié le discard sur les options de montage de la storageClass.

OK, j'ai corrigé la storageClass.

Maintenant... comment je corrige les PVC en fait ?

J'ai collé fstrim à l'arrache en attendant, mais c'est cracra.
