November 9, 2025Nov 9 I was checking the contents of a SSDs via my USB3 cradle (it never was trouble), working directly with the server's display and keyboard. Once appearing as an Unassigned drive, I attempted to mount it. Instantly, the GUI was replaced by the console and a flurry of lines, and the system shut down in maybe ten seconds.Fearing the worst, I booted and logged in, but I saw no warnings about any need to rebuild the parity data anywhere. Not restarting the Array just yet, I tried mounting the SSD's volume again, and this time it worked normally. After perusing its contents, I unmounted it and switched the cradle off.Then I started the Array. Again, no warnings of anything wrong with the parity data. The only notification was one of the SSD having showed an inordinate amount of CRC errors (although I seem to remember those not being real but some kind of artifact).I'm checking syslog-previous. As I'm a complete novice, I don't understand it, but I can see the references to the "SuperSpeed USB device" (the SSD), and what feels like an orderly shutdown process. I would be grateful if somebody could give it a look and opine on it.syslog-previous.txt Edited November 9, 2025Nov 9 by MetricTonto

The PC case is set in such a way that the button is difficult to reach. The cradle has one of those buttons meant to trigger a Windows HDD cloner app, though. I wonder if I pressed that one without meaning to and it produced a similar reaction. I'll have to test that.In any case, thank you for giving it a look 🙂.
November 11, 2025Nov 11 Author OK, so, it was the no-name PC keyboard's power down button 😑 (I never use such, and I used to have a Mac keyboard there instead). I wonder if I can disable that in the BIOS or somewhere else.
November 11, 2025Nov 11 Author This motherboard's BIOS at the very least allows for setting it to require a four seconds button press for it to act.
