Block volume sometimes takes 5 minutes

[sathieu]

Is this a BUG REPORT or FEATURE REQUEST?:

/kind bug

What happened:

PVC ReadWriteOnce sometimes takes 5 minutes to be provisionned (i.e. PV to be created) unless we set NetPermissions in the config.

This seems very strange because NetPermissions is relative to ReadWriteMany PVCs (which we don't use).

NB: we use --timeout=300s (see here)

What you expected to happen:

No delay

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:

Environment:

• csi-vsphere version: v3.1.1
• vsphere-cloud-controller-manager version:
• Kubernetes version: 1.27.7
• vSphere version: 7.0.3.01700
• OS (e.g. from /etc/os-release):
• Kernel (e.g. uname -a):
• Install tools:
• Others:

@sathieu Net Permissions in the config secret and Volume Creation is taking longer are not related.

What is the size of your volume and are you creating thin, thick or egar-zeroed thick volume?

[sathieu]

@divyenpatel I confirm that Net Permissions is not changing the delay. The delay is sometimes high and we don't yet know why.

We use Thin provisioning (set in the storage policy).

I forgot to answer about the size of the volume: we tried 1Gi and 500Gi. The problem occurred only with 500Gi disks.
