Bug Report

I see a lot of the following error:

 GRPC error: rpc error: code = Internal desc = 500 hostname lookup 'default' failed - failed to get address info for: default: Temporary failure in name resolution                                                                                                          │

my config looks like:

    config:

        ssd: true
        cache: none

I have no idea why 'default' will be looked up

Hello,

config:
      clusters:
        - url: https://pve.redacted.de:8006/api2/json
          insecure: true
          token_id: "kubernetes-csi@pve!csi"
          token_secret: redacted
          region: default

region is your proxmox node name. You can get node list by command pvecm nodes

[sergelogvinov]

Oh, sorry,

region is your proxmox cluster name... It can be every thing...

[sergelogvinov]

So, what's the pod has such message - GRPC error: rpc error: code = Internal

[markussiebert]

trying your latest suggestions ...

Maybe I should describe my setup ... this is proxmox: This is my k8s node:

so the container complaining are csi-provisioner and plugin-controller

The pvc itself has the following error message: failed to provision volume with StorageClass "proxmox-data-xfs": rpc error: code = Internal desc = proxmox cluster pve-cluster not found

And btw. thank you a lot for your help...

wait a moment ... might be a failure in my dns setup

[markussiebert]

Thank you - after getting region and zone right (cluster / node) it works!
