Update Smartctl Database

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.
