I have been trying to understand if the bug mentioned with Thunderbolt devices has been resolved by any of the latest kernel updates, I’m on 6.8.12-7.

I know people use Thunderbolt for many things, eGPU, NIC etc. in my case I am wanting to connect a 4 disc DAS over thunderbolt 3 which exposes the discs contained as block devices, to then create a zfs raidz pool and use something like cockpit to then create shares. The DAS I will use has PCIe x4.

I see various reports of people not being able to boot, or devices not recognized, and the solution often proposed is to modify the kernel with thunderbolt.host_reset=0 which would revert to legacy behaviour in this context, or else to pin an older kernel version.

I tried to find some sort of official bug report, all I could see was something from Ubuntu https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/2078573

However, this seems to basically say that actually the problem people are reporting is not a bug, but that maybe initramfs-tools needs to be modified.

Admittedly my understanding is limited of this issue, but to be clear I don’t want to boot from an external drive; I will use a separate M2 drive as my boot drive and I will be storing all of my VM’s on the M2.

I only want to use this external array to share file content and I’d like to allow access to a couple of LXC’s.

Assuming my hardware is fully supported by the BIOS, can I, on the latest kernel, simply:

  1. Connect a Thunderbolt 3 DAS
  2. Install bolt on the host
  3. Enroll and authorize the device
  4. Expect it to function as intended without kernel modifications?
 
Hey,

i'm in the same boat here.

My host hardware (Intel based) offers 2 Thunderbolt 4 ports and it would be a real waste, not to make use of them.
Would like to connect a 8 drive chassis (ARECA) with Thunderbolt 3 connection (using JBOD mode).

Any information/help on this would be great!

New to community, Proxmox & homelabbing here,

I am third in row (reporting here). Wonder what could be the limitation, I am using a SFF Lenovo PC having limited space to install HDD's in case. Recently purchased a TB DAS, but my current install somehow boot loops as I activate TB in bios! Haven't tried for GPU's as I don't own any. Can we be assisted over here community ?
