File recovery in process...

Ohai,

I have some pending, encrypted mails to answer. And some of my answers for the next few days (particularly to what pertains to the current in-discussion vote on LLM usage in Debian) will be unsigned, even though I’d like otherwise.

My desktop system at work is showing some data corruption, and I’m slowly backing up my data. Fortunately, it seems I haven’t lost any data, but still, given I’m letting rsync run until it starts spewing I/O errors, then power down and let the machine cool a bit, and start again… it is a potentially long process.

And yes, this makes me somewhat angry. Why angry? Because I’m working on a brand-new computer (well, have used it for slightly over six months), custom-built to specs requested by my workplace. Specs that I don’t really need, this machine is an utter luxury (i.e. an AMD Ryzen 9 9950X processor with 16 real cores / 32 threads; 128GB RAM in this day and age of RAM shortage, quite recent 32GB GPU, and lots of shiny lights seen in its huge fishbowl cabinet, liquid-based cooling…). The specs came not from me, but from people who had no idea what we would use them for. And yes, I expect the little fortune spent on this machine to be good for my use for probably a decade, as my previous computer was, but the amount paid was… exorbitant.

But still, what I learned recently is that the 4TB nVME SSD it has (a T-Force TM8FFJX34T) is… a very cheap brand, bought because it was close to half the price of other offerings similar in capacity. According to smartctl’s output, th SSD operates with a Warning Comp. Temp. Threshold: 90 Celsius and Critical Comp. Temp. Threshold: 110 Celsius, which sounds sensible, even too high for my standards (my last two laptops have been fanless… yes, an ARM system is very different from a high-end gaming machine). I’m right now typing from my laptop, which shows 78°C and 82°C for warning/critical thresholds.

And as expected, under heavy sustained reads (backing up to my NFS server), the desktop’s smartctl shows Temperature: 83 Celsius and, further down, Temperature Sensor 1: 107 Celsius and Temperature Sensor 2: 82 Celsius (don’t know which of these would make the threshold jump). The SSD has sustained Media and Data Integrity Errors: 20 and Warning Comp. Temperature Time: 21 (although Critical Comp. Temperature Time: 0). At least one of my colleagues have shrugged and installed a SATA SSD, laying the huge nVME basically to waste.

Anyway… I also learned I am not the first, but the fourth person to notice this kind of issues in this system (out of ten similar purchased systems AIUI). It is completely unacceptable, and I’ll be pushing our Institute’s authorities to demand the provider to provide either good component quality for this very expensive system that has many luxury items, or to fix the system’s build in a way the nVME does not heat as much as it currently does.

Anyway, sigh, I only wanted to say, please excuse me for not using my cryptographic keys for a couple of days 🙃

PS- I’m also currently not connected to IRC and Jabber (and some similar technologies), as my bouncer runs from my usual workstation.
