unable to activate logical volumes: Volume group "csi-lvm" not found

[m0sh1x2]

Hello,

I am testing out a local setup with minikube and KubeVirt and I want to use the csi-driver-lvm on a freshly formatted disk but once I set up everything I eventually get some failures:

$ k logs csi-driver-lvm-plugin-f8rvp csi-driver-lvm-plugin

Here are the setps that I take:

1. Format the disk fdisk /dev/sdb -> d -> n -> p -> 1 -> Select Sectors -> Format -> w save
2. Set up the helm repo:

helm repo add metal-stack https://helm.metal-stack.io

3. Install everything:

helm install mytest metal-stack/csi-driver-lvm --set lvm.devicePattern='/dev/sdb1'

4. get the pods

 k get po
NAME                          READY   STATUS    RESTARTS   AGE
csi-driver-lvm-controller-0   3/3     Running   0          7m33s
csi-driver-lvm-plugin-v4jfd   3/3     Running   0          9m14s

5. Check vgs, pvs, create the example pods, check the storageclasses:

$ ​kubectl apply -f examples/csi-pvc-raw.yaml
kubectl apply -f examples/csi-pod-raw.yaml
kubectl apply -f examples/csi-pvc.yaml

Any help would be of a great assistance, thanks.

You have to ensure that the devicepattern in the values.yaml matches your disks/partitions.

Thanks!
It works like a charm!

Here are the steps that I used in case someoene gets stuck in the future:

helm get values mytest -a > values.yaml
# Set devicePattern to /dev/sdb1 or the name of your disks/partitions
helm upgrade mytest helm/csi-driver-lvm -f values.yaml
