With the help of GPT-o1, I am successfully passing through Thunderbolt enclosure discs to unraid, and I have eliminated any activity from the Proxmox host on those discs. It involves passing through the discs as SATA rather than SCSI, and hiding the discs from Proxmox . This technique does not remove them from the lsblk list, but it effectively hides them from Proxmox and eliminates any activity from Proxmox as demonstrated by the iotop command.. I would suggest consulting GPT-o1 (or its successor) if you want to do it for your own system. Create Udev Rules to Ignore the Disks nano /etc/udev/rules.d/99-ignore-passthrough-disks.rules Add the Following Rules: # Ignore disk ata-ST8000VN004-3CP101_WWZ5M6LD KERNEL=="sd*", ENV{ID_SERIAL_SHORT}=="WWZ5M6LD", OPTIONS:="ignore_device" # Ignore disk ata-ST8000VN004-3CP101_WWZ5SWZ2 KERNEL=="sd*", ENV{ID_SERIAL_SHORT}=="WWZ5SWZ2", OPTIONS:="ignore_device" Explanation: KERNEL=="sd*": Matches all SCSI disk devices. ENV{ID_SERIAL_SHORT}=="WWZ5M6LD": Targets the disk with serial WWZ5M6LD. OPTIONS:="ignore_device": Instructs udev to ignore the device. Make sure to replace WWZ5M6LD and WWZ5SWZ2 with the exact serial numbers from your disks. Reload Udev Rules: udevadm control --reload-rules Trigger Udev to Apply the Rules: udevadm trigger --attr-match=ID_SERIAL_SHORT=WWZ5M6LD udevadm trigger --attr-match=ID_SERIAL_SHORT=WWZ5SWZ2 For bmartino1: your insulting comments in the other thread you started were not appreciated.

How does it kill the disc? HBA is not an option because I am running on a Mini PC with these specifications. Proxmox Server Specification: Minisforum EM680 Processor AMD Ryzen™ 7 6800U 8 Cores / 16 Threads 16M L3 cache, up to 4.7 GHz Graphics AMD Radeon™ 680M Graphics Frequency: 2200 MHz Memory LPDDR5 Dual Channel (Onboard) 16GB, 6400 MHz Storage M.2 2230 PCIe 4.0 SSD ×1 (up to 2TB) Storage Expansion TF Card Slot ×1 Wireless Connectivity Wi-Fi 6E, Bluetooth 5.3 Video Output HDMI 2.1 (4K @ 60Hz) ×1 USB4 (8K @ 60Hz) ×2 Audio Output HDMI 2.1 ×1 Audio Jack ×1 Ports & Buttons USB 3.2 Gen2 Type-A Port ×3 USB4 Port ×2 (Alt PD) TF Card Slot ×1 HDMI 2.1 ×1 Audio Jack ×1 DMIC ×1 Clear CMOS ×1 Power 65W GaN Type-C Power Delivery Adapter (Included) Product Dimensions 80 × 80 × 43 mm

As a reminder, I'm using a thunderbolt connection to the discs, so I'm not sure HBA applies. Here's what GPT-o1 says about passing through the discs as SATA: ================================ Since you're passing the disks through to Unraid and not using ZFS, and SMART monitoring is working, that's great news. Your current setup appears to be effective, and there are no significant disadvantages if everything is functioning as intended. Advantages of Your Current Setup Direct Disk Access: Unraid Compatibility: Passing the disks directly to Unraid allows it to manage the disks as if it were running on bare metal. This is ideal because Unraid's storage system benefits from direct access to individual disks. Flexibility: Unraid can use its proprietary parity and storage management features without interference from the host. SMART Monitoring: Disk Health Monitoring: Having SMART data accessible within Unraid enables you to monitor the health of your disks, predict failures, and take proactive measures. Maintenance: You can perform disk checks, schedule maintenance, and receive alerts directly within Unraid. Performance: Efficiency: Passing through disks at the hardware level minimizes virtualization overhead, potentially offering near-native performance. Simplicity: This method avoids the complexity of setting up and managing additional layers like ZFS on the host. No Significant Disadvantages Given that: SMART Monitoring Works: You have full visibility into disk health. Performance Meets Needs: There are no performance bottlenecks impacting your use case. Stability Is Maintained: The system operates reliably without crashes or data corruption. There are no significant disadvantages to your current approach. Passing the disks directly to Unraid is a common practice and is supported by both Proxmox and Unraid communities. Conclusion Your current method of passing the disks through to Unraid as SATA devices is effective and appropriate for your needs. Since SMART monitoring is operational and you're not experiencing any issues, there's no inherent disadvantage to this setup.

I am running unraid as a VM under Proxmox. After a couple of hours with GPT-o1 today, I figured out that I have to pass through the drives as SATA instead of SCSI. That fixed it.

I am using an AMD-based x86 Mini PC with a thunderbolt 4 Port, not a Mac. Unraid sees the discs just fine, and they are part of an array that is running fine. I can see the smart reports from the Linux command line, but not in unraid. The question is: how do I make unraid see the smart capability of the discs?

How are your drives connected to your server? I was wondering whether it might be a problem with Thunderbolt 4 or my Thunderbay enclosure. Where did you submit your ticket? I'll put one in also.

Did you ever get a resolution on this? I have a similar situation with two ironwolf pro 8TB drives in a Thunderbay 4 DAS. I can see the smart reports from the command line but not from unraid.
