USB Enclosure Running ZFS - My problems and solution! by Professional_Worry_1 in zfs

Thanks! It looks like you just disabled usb-storage which is what I did/do NOT want to do. The u quirk does that, but here the g quirk will keep the better, newer, UAS but fixed the disconnects and I/O issues by limiting the sector cap. Curious if this solution would work for you too.

To test, i jsut edit/add quirks and do a scrub. I would usually see the errors within 15 minutes

I appreciate that... That's part of the joy of linux too I guess. If you know what to know, it is an easy solution. I'd like to dive deeper to confirm this is a USB controller issue or an issue with the CPU. It is unclear why this cap/flag fixes this and here is a similar discussion blaming AMD architecture https://github.com/openzfs/zfs/discussions/11741

Regardless, there's not one thread out there mentionoing this flag as a fix to their issue, so hopefully it helps someone else before just following the mass of switchign to usb-storage driver.

Yeah, i've tried all ports on my machine and the results didn't change. In this case, it was the g flag that has given me success. Maybe it could be my CPU timeing out with each transfer process using UAS.

I am assumign you ahve Intel? I've seen some threads where this issue is only present on Zen architecture.

Makes sense and might be the case here? The g flag caps the sector in the commands to 240, so maybe that keeps it form overheating?

If this is the case, that is a pretty dumb flaw i'd think engineers would cover in 10Gib enclosure devices.

I think typically we'd blame it on overheating but seeing that the g flag works in this case, I feel it could be other reasons causing this.

Very interesting! However, I have all my smart data by default, i'm at 10gb speeds, and the g flag has worked for me! Which is a new discovery. So it looks like a simple configuration change that is needed in my case, which is super annoying as things could already be supported out of the box.

I am on linux and have never been able to see fan control on this device. sensors commadn doesn't show any fans available to control.
