As the title says. My system is built with an AMD mini PC with several USB 4(so Thunderbolt/40 Gbps compatible) ports, two nvme drives, and multiple hard drive enclosures loaded with an assortment of had drives. Originally, I had been using two Terramaster enclosures for the last 5 years or so. Rock solid, but only 5Gbps usb connection, so it's slower the dirt. Finally decided it's time for an upgrade to both storage and speed, so I hit up black friday sales and managed to get an Orico 5-bay Thunderbolt enclosure, a MediaSonic 8-bay 10Gbps enclosure, and a handful of WD 8TB drives. Moved my drives over from the Terramaster enclosures to the MediaSonic, put the new 8TB drives into the Orico, paid the $69 to upgrade my key from Plus to Pro(now that I am over 12 drives), and I was back up and running in less than 30 minutes, faster than ever, and with double the storage.

 

Unfortunately, I've been watching SpaceInvader's tutorial videos on setting up Tailscale and other newer features, which made me decide that as long as I am doing upgrades, I may as well try getting on Unraid 7. Ran the upgrade, rebooted, and immediately the Thunderbolt enclosure and drives were no longer detected. Though I knew it wasn't the problem, I spent a bunch of time mucking around with power cycling the enclosure and server, swapping cables, etc. Nothing. Hit the button to downgrade back to 6.12.14, the enclosure and drives immediately work again. The non-Thunderbolt enclosure worked the whole time with no issue.

 

So I'm wondering, anyone else have this issue? Is this a known thing, maybe? Is there a fix? Anything I can do at all to get on Unraid 7 with my hardware setup? Or can I expect that if it doesn't work anymore in RC1, that it's probably going to continue to not work in the official Unraid 7 release? Any time I search for "thunderbolt" in these forums, it's just posts about people wanting to use Thunderbolt networking, and no real useful information in fixing anything, regardless. Back on 6.12.14 for now, but I'd rather not be trapped on Unraid 6 and locked out of new features, and I also have no intention of downgrading the hardware back to the much slower stuff. So I'm not really sure what to do here.

 

*edit* Decided to search again, and I found some threads I didn't find last time, somehow. People discussing exactly this. Wis I could delete this post now, as it is pointless. Also, seems like the answer is basically "no, there is no solution"

One more update to this, just in case anyone finds this post because they have the same/similar issue.

 

I had decided that even if my Thunderbolt enclosure wouldn't work anymore on Unraid, maybe I could still make use of the enclosure and drives if I were to pass the Thunderbolt controller through to a VM running an OS that CAN make use of it. So of course I went to Tools/System Devices, found the USB4/Thunderbolt controller on the list, checked the box, and hit the "Bind selected to VFIO at boot" button, and rebooted. Wouldn't you know it, when I rebooted and logged back in, all of the drives in that enclosure were suddenly appearing under Unassigned Devices, and I was able to stop the array and add those drives in and start the array back up.

 

And just like that, my array just regrew by 32TB that I thought was just going to sit around doing nothing after updating to Unraid 7. I feel stupid for not thinking to try such a simple step 4 months ago, but I guess better late than never.

There are some reports that Thunderbolt works better with 7.1.0-beta, due to the much newer kernel, so also may be worth a try.
