extend /data thin-provisioned

I have a machine with 7 drives. Proxmox is installed on the first. I would like to use the others for storage of VM disks, ISO images, etc.

From lsblk:

What is the right way to "extend" the "data" storage with these disks.

I can do a standard logical volume and mount it, then create a "Directory" storage. Alas, it seems this can only store one type of data.

Is there some sort of "advance installation" or "storage configuration" document I should be reading?

There are always a few "right" ways. The one that is right for you depends on your exact requirements and constraints.
Do you need data protection?
Do you want one big pool or a few smaller ones?
Are you ok with storing VM disks/images as raw/qcow files vs having them as block devices?

You already have an existing LVM data pool most likely. However, I would not recommend extending that nvme pool with HDDs.

Your course of action depends on the data protection layer you require. Looks like you could create two normal R1s and one "degraded" (different size disks force matched).

If you dont care about disk protection then you could create a new LVM pool, slice a portion of it for a filesystem of your choice for ISOs, use the rest for VMs. Or just create a single slice of the same size as pool, format and mount it.

Many different options, perhaps you should just experiment and see what you like best.
