I hope this is correctly placed. Its kind of a proxmox question but it seems like there's actually more literature and expertise on the OMV side 
I did a OMV VM on a Proxmox container, and have passed-through 3 drives, 2 8TB and a single 1GB drive through virtio and scsi-over-virtio interfaces (was testing)
The virutalized drives are seen and fdisk, etc. can be run on the OMV side, so I've wiped and pooled the drives, for example
However, I can't seem to get SMART configuration going on the OMV side. DMs to other OMV users who have a proxmox host suggest that its possible, but there are also forum posts contradicting this.
Curious for the expertise of power-users.
The end usecase is to configure email notifications for SMART failures, which as a fallback I can try to figure out on the host side, but was hoping to do 100% of the management (configuration, file system, etc.) of these drives within the guest
