I'll add another disk write case, though it's in ISC DHCP which is deprecated. I find "Ignore denied clients rather than reject" sometimes will log the rejection even if the option is checked, which usually results in a log entry every few seconds. Restarting DHCP Server seems to fix it (no log), and at some point later (update? restart? random?) I will find it is logging again.
-
"Thinking out loud here" :
If a (DHCP) client was set to be rejected, it will do the reject (it will answer "no") and normally, the client should take "no" for an answer - the the sofware is RFC compliant (I guess).
Let's consider 'ISC DHCP' as the old generation.
But its 2025, the client is probably a new generation DHCP client and won't take no for an answer, do'nt bother with RFC, so it keeps on insisting.
Now, ISC DHCP start to log.It's in the admin's authority to take things one level up. It was the admin after all who decided who to serve, and who to reject.
Go visit the client, and tell him who is boss in the town.
Next step : MAC black list the guy and call it a day. -
fwiw, It appears that Netgate only offers the 4200 with the 128Gb SSD, probably due to the eMMC issues.

Just for reference here's my 6100 MAX failure story:
https://forum.netgate.com/topic/198361/6100-max-nvme-failed -
Wow...
very interesting thread.
I found this just yesterday and it takes me half the night to to read it from start to end
.
Actually I am using a SG-3100 device which I switched to SATA SSD abt. 3 years ago.
I was thinking about replacing it with a newer appliance, i.e. a SG-4200, thats why I am looking around here.
To be honest, there is no technical reason for that, it was just to keep pfSense at the latest.
But just this days a new v25.07 was released so I will keep my SG-3100 for a while.And BTW: the SMART values shows the SSD is still at 94% lifetime, so I can run the device may be until a 4300/4400/4x00 is availabe
.Regards

I confirm, I had no idea. Don't recall seeing it mentioned in the marketing data, docs, nor by the gurus at YT.
I've chosen NG's hw specifically for the reliability and minimal maintenance. Knowing this probably would go 'max'.Adjusted the timings, no sync for tmp. Soon on my way for new ssd. Thanks.
Can you advice me how can I check emmc healt in SG2100?

@arri Please, I need help with my bricked 6100 base model. Everything was working fine until the device stopped booting. I had no console access, and the power LED was solid blue. As many people suggested, I was able to remove the EMMC from the device with professional assistance and slotted in a B+M keyed NVMe SSD. I still don't get console access, and the power LED is solid blue. I have tried the USB installer, and still the same thing. Sadly, I am losing $890. Is there anyone who has been able to succeed with this before?

By correctly (without creating shorts or cuts in the traces) removing the EMMC and the BIOS can't find it anymore, and will look for other potential "drives" so it can boot from it.
A broken EMMC, imho, won't stop the processor from running the BIOS and communicate with you over the console.
No console is scary : no real proof the processor runs.
You've used the console access before ? Was it working before on this device ? Is your console cable ok ?
If the power rail is good, but for some reason it sinks the (example) 'common' clock signal to ground, then your processor can't work anymore.
Some good equipment (scoop, or even logic analyser) and schemas and the knowledge how to (electrically) debug this is now needed. Humm, sorry, I start to feel pessimistic about this. -

Please, the console used to work until the device didn't respond again. But is it possible that the computer can detect the COM port but still not be functional? I am really frustrated. The money wasted is so sad to think about.

Ok, so chances are good that the cable is ok.
Removing the EMMC was a guess then ?The '6100' is like a PC : removing a drive won't stop the system from booting. You need the console access to select from what device : an EMMC, or some SSD drive or even a USB key drive. Whatever happens with these "drives", the console will give output.
@ablephri said in Another Netgate with storage failure, 6 in total so far:

On the computer side, the USB plug, and the USB chip build into the cable, will power up, and communicate with the USB host (the USB circuitry build in the PC) so the 'PC' knows that an USB device is present, and with the help of the 'ID' of the USB cable chip, it will know what kind of driver it needs. In this case : a serial connection driver, also known as a 'COM' port (in the PC world) type of device. The serial connection itself, 3 wires, a common ground, a transmit and receive line, can not be auto detected like what you see if something is "plug and play". A serial connection is something from te past century.
So plugin in the cable makes the COM port avaible to the PC, but won't tell you anything about the presence of a connection = the receive line going up and down in a fixed frequency (115000 hz - you checked this bit rate of you port ? ) so a serial connection is establish.
That's also you final test : on the console port, if you can find these 'TX' and RX' traces, locate the TX line.
If you see the TX line go up and down frequently (shortly) after power up, you know the 6100 BIOS is outputting text. If it stays silent ........
-
@Gertjan Unfortunately, the COM port shows, but there's no connection on Putty.
-
@Gertjan This is the status static lights i get on the device. Do they mean anything?

@ablephri come on, post the video of the 1500W heat gun that was used, like you did on reddit.
note to others in this thread: I'm working with him off-thread to get him a replacement in exchange for his broken unit.

Does the external LED start orange then change to blue?
The diag LEDs look like a normal POST.
Did you try both console ports?

To generally address this thread:
A larger flash device is only part of the solution. Netgate moved the entire product line to a larger eMMC device running in pSLC mode much earlier this year, without a price increase.
The larger pSLC isn't because there are more flash sectors to write to as much as it is to compensate for running the eMMC in pSLC mode, and yield the same or larger effective capacity. So now you'll see (for example) the Storage capacity on the 6100 Base as
Storage: 21.3 GB eMMC
This is really a 64GB eMMC running in pSLC mode.
Running the eMMC in pSLC mode provides a write endurance far beyond just the capacity increase of the new eMMC.
I'll try to write up something more ... technical to explain why soon.
Now I see a number of people desoldering the eMMC to try to recover. I'm not saying that isn't necessary, but I will say that it should not be necessary. I'm working with the vendor here to attempt to establish 'why' and issue a remedy.
I also want to work with the customer base for existing (pre-SLC eMMC) units to establish a path to getting a working, supported NVMe drive installed in their Netgate device prior to failure of the eMMC.
-
@jwt Hahaha yeah. I had to give it to a "professional" who used that heat gun.
I am delighted with Netgate's great customer service, and I really appreciate the patience Gonzo had with me trying to fix my problems and also get the unit replaced -
