I don't think so. When ECC RAM encounters an uncorrectable error, the system is halted.
That'd normally be a double bit error though which is fairly rare.

Unless you have your NAS sitting outside in a field or a tree, the electrical surge is going to have to flow into your facility via some wiring. And it's worth pointing out that there is more than just the power path that an electrical surge can take. I've had a cable modem and the connected router both fried do to a close strike. Which reminds me, I need to go buy that optical ethernet isolator.
Ahh, I see. Long week.
I've already got a UBNT ERL. It's disposable, but still takes effort to replace which is why I wanted to put something upstream. I like the looks of the APC PN RM though. Haven't used that before.
Yes.Can I simply move the USB stick and the drives to the new motherboard?
Expect something between "constant errors" and "works reliably, but is very slow".A little update for anyone interested:
The C2750D4I is weird. First time I turned it on it just sat there with a blinking LED, no POST, no VGA output at all. Thought maybe the RAM was defective so I swapped out some regular DDR3 i knew to be working. Still wouldn't boot. Eventually I gave up and went to make coffee. I wouldn't have thought to leave it on for five minutes, but that just happened to be how I left it, and when I came back the monitor was flickering on and off, with alternating messages of "no signal" and "unsupported signal", but a garbled FreeNAS boot sequence half visible in the background. Eventually the image stabilised, though, and FreeNAS was up and running. So I swapped in the ECC RAM and it took several minutes to start up again, but it did boot eventually.
Rebooting is quick enough, but it still goes through the same thing whenever i cold boot. Weird. Maybe it runs a long self diagnostic or something, who knows. But anyway, for anyone having problems with that board, I recommend giving it a good long time to start up, because apparently it needs it.
With the board running, FreeNAS appears to be very stable. The pool is present and it retained all of my settings including the Syncthing jail. Even network settings were retained. Only thing I needed to reconfigure was the USB port for the BBU which took all of five seconds. Pretty impressive, TBH.
So about the Marvell SATA controller:
I plan to add another 4-drive vdev some time in the future. I've only got two ports left on the intel controller, though. So can anyone elaborate on the problems with the Marvell SE9230 controller? And if it's really that problematic, who can recommend a suitable expansion board? (I have one PCIe 2.0 x 8 slot.)
