flyize Posted November 28, 2022 Share Posted November 28, 2022 Any ideas what could be wrong here? It's been running fine for quite a while... truffle-diagnostics-20221128-1636.zip Quote Link to comment

It used to be around 170-200MB/s until very recently. I run a Plex server and Plex was also running terribly when the Parity was running, which is also a new problem. Quote Link to comment
JorgeB Posted November 29, 2022 Share Posted November 29, 2022 I meant is it still going at 20MB/s? It could have been a slower zone on one of the disks. Quote Link to comment
flyize Posted November 29, 2022 Author Share Posted November 29, 2022 I was on vacation, so I didn't stop it. Yes, it had been running for 4 days (and needed 4-8 more, I don't remember). And when I start it now, I get the same speed. Quote Link to comment
JorgeB Posted November 29, 2022 Share Posted November 29, 2022 Run the diskpeed controller benchmark, to rule out any bottlenecks there. Quote Link to comment
flyize Posted November 29, 2022 Author Share Posted November 29, 2022 Everything there looks good. The only thing it seems I can't test is an external USB 3.2 enclosure with a couple of drives in it. While that might sound crazy, I tested it extensively when adding it about 6 months ago and it's seemingly working fine. Unless maybe there were some USB changes in one of the latest point releases?

flyize Posted November 29, 2022 Author Share Posted November 29, 2022 I'll be damned, you're right. Is there anything you can think of that would have changed with USB in the last month or so? I just did a quick CTRL+F for USB on the latest 6.11 releases, and I don't see anything obvious. I'm quite positive this worked without issue before. Quote Link to comment
JorgeB Posted November 29, 2022 Share Posted November 29, 2022 Possibly some quirks added to the kernel for the USB bridge: usb-storage 1-5.3.3:1.0: Quirks match for vid 174c pid 55aa: 400000 It might be downgrading the speed to USB 2.0, we really don't recommend USB for array/pool devices.

flyize Posted November 29, 2022 Author Share Posted November 29, 2022 I'll be damned. That's it. Anything I can do? When was this added? I'd like to roll back and test (unless you're sure that's the issue). While I doubt it matters, this is the one I purchased. https://www.amazon.com/gp/product/B07Y3WDHLD Quote Link to comment

flyize Posted November 29, 2022 Author Share Posted November 29, 2022 Would it be possible for me to find out more information from somewhere? I'd really rather not abandon this thing unless I have to... Quote Link to comment
JorgeB Posted November 29, 2022 Share Posted November 29, 2022 Probably there's a comment in the kernel to why the quirk was added, but sorry, no idea how to find that. Quote Link to comment
flyize Posted November 29, 2022 Author Share Posted November 29, 2022 Yeah, shouldn't there be a repo somewhere for us to check? It's GPL'd code... Quote Link to comment
flyize Posted November 30, 2022 Author Share Posted November 30, 2022 Anyone else here know where I can find out more information about this change? Thanks! Quote Link to comment
flyize Posted December 1, 2022 Author Share Posted December 1, 2022 (edited) @limetech any chance you might be able to share some quick wisdom here? Edited December 1, 2022 by flyize Quote Link to comment
flyize Posted December 4, 2022 Author Share Posted December 4, 2022 Anyone have any idea or am I just dead in the water with this USB enclosure? Quote Link to comment
ConnerVT Posted December 4, 2022 Share Posted December 4, 2022 Not even close to an expert at this. But a quick Google search of "ASM1153 SATA 3Gb/s bridge" finds many hits going back ro 2017 and beyond, with other ASM chips at 6Gb/s. Makes me think nothing may have changed in the base kernel/drivers of Linux in general. 1 Quote Link to comment

It worked flawlessly before that. Quote Link to comment
Solution flyize Posted December 6, 2022 Author Solution Share Posted December 6, 2022 I managed to 3d print an extra drive cage to go into my Unraid server. Sucks, but I guess I'll just sell this enclosure. Quote Link to comment
