Hi @zfrhv, this is already possible by specifying deviceSelector.paths option under deviceClasses like:

apiVersion: lvm.topolvm.io/v1alpha1
kind: LVMCluster
metadata:
  name: my-lvmcluster
spec:
  storage:
    deviceClasses:
    - name: vg1
      thinPoolConfig:
        name: thin-pool-1
        sizePercent: 90
        overprovisionRatio: 10
      deviceSelector:
        paths:
        - /dev/nvme1n1p1 
        - /dev/nvme1n1p2

This will create a StorageClass which will use the specified partitions to create a volume group.

You can also specify multiple device classes with paths pointing to different partitions like:

apiVersion: lvm.topolvm.io/v1alpha1
kind: LVMCluster
metadata:
  name: my-lvmcluster
spec:
  storage:
    deviceClasses:
    - name: vg1
      thinPoolConfig:
        name: thin-pool-1
        sizePercent: 90
        overprovisionRatio: 10
      deviceSelector:
        paths:
        - /dev/nvme1n1p1
      default: true
    - name: vg2
      thinPoolConfig:
        name: thin-pool-2
        sizePercent: 90
        overprovisionRatio: 10
      deviceSelector:
        paths:
        - /dev/nvme1n1p2

This will then create two different StorageClasses making use of the corresponding partitions specified under paths.

thank you very much for the detailed explanation!
we will try it !

hello,
i tried to configure:

deviceSelector:
  paths:
  - /dev/nvme0n1p5

but after applying the yaml it returns to:

deviceSelector: {}

seems like the operator overrides that field to empty object.

nothing in the logs, nothing happens
im using ODF LVM 4.10.7

should i open an issue or try to upgrade the operator?

Hi @zfrhv, could you please try it with the 4.12 version of the operator? 4.10 and 4.11 were tech preview releases so they are not supported, and 4.12 is the GA release.
