I’m running a heterogeneous on-premise cluster with NVMe disks:

• Some nodes have 1 NVMe disk
• Some nodes have 2 NVMe disk
• Some nodes have 3 NVMe disks

For reliability reasons, I don’t want to create a single VG spanning multiple disks (since one disk failure would cause data loss).
Instead, I create multiple VGs per node, for example:

• nvme1
• nvme2
• nvme3

From a user perspective, it would be much nicer if workloads could just use a single StorageClass like lvm-nvme, instead of having to know about and choose between lvm-nvme1, lvm-nvme2, lvm-nvme3.

Feature request

• Allow a StorageClass to reference multiple VGs on a node.
• TopoLVM would then provision volumes from any available VG within that group.

Benefits:

• Simplifies UX (users don’t need to know disk/VG details).
• Works well with heterogeneous nodes (different number of disks).

Is there maybe a way to achieve this today with existing features?

Thanks!
