I broke my system with a BIOS Upgrade

[kirkdickinson]

I have had a problem with my system fan racing and stopping, racing and stopping. I saw somewhere to start with a BIOS Upgrade. I just finished that, but it broke my TrueNAS install.

Unfortunately, it didn't fix my main issue. "The fan pulsing on and off"

I can no longer boot into my TrueNAS system. I checked the BIOS and the first boot item is "SuperMicro DOM" which is my boot. I get a message saying that it can't boot due to the fact that "This is a FreeNAS data disk and can not boot system."

I have two SuperMicro DOMs installe that are mirrored by TrueNAS.

I hope there is an easy answer for this?

Thanks,

Kirk

OK, solved. The Bios didn't like Legacy with the drive picked specifically. I had to select EUFI, and it booted.

Whoo!

Still have the fan racing issue. :(

Fan pulsing issue. Supermicro helped me figure this out. The Mobo is looking for an authentic Supermicro fan that can run at 28,000 RPM. Yeah, you read that right. It is a tiny little fan that pushes almost 30CFM of air. The case and fans that I have are much bigger, only run at 1500 RPM, but push plenty of air. I just set my fans to High speed and they will stay there, which is fine.

Excellent news. As for the fans on Supermicro MBs, a more elaborate solution is here:

PID fan controller Perl script

I can't post in Useful Scripts, so Hardware will have to do. I've updated @Stux's hybrid fan controller script to replace his HD fan control logic (which uses three discrete fan duty cycles as a function of warmest HD temperature) with a PID control loop, which controls duty cycle in 1%...

Cool, thanks.

I read several pages on those threads and it must be self evident to those who are posting there, but I don't know. Where do you put the script and how do you start it?

One thing to keep in mind is it is not only the volume of air being pushed through the chassis (e.g., cfm) but also the pressure of the air flow (in Hg). The air has to have enough pressure to be pushed over/through the heat sinks for the CPUs, between the RAM modules, etc. I looked at replacing the fans on my Supermicro chassis (see signature) with Nocturas but in emails with Noctura they do not have those nice quiet fans with enough air pressure.

Don't think I have any problem with cooling. Just the SM BIOS is pulsing the fans. I do not have this in a SuperMicro 1U case with the very small high speed high flow fans, but a 4U iStar case with much bigger fans. The larger fans can get the proper airflow and cooling without the high RPM.

I don't think I need to worry about cooling. Here are my numbers:

Code:

CPU Temp        Normal    37 degrees C
PCH Temp        Normal    32 degrees C
System Temp        Normal    31 degrees C
Peripheral Temp    Normal    37 degrees C
VcpuVRM Temp    Normal    34 degrees C
DIMMA1 Temp        N/A    Not Present
DIMMA2 Temp        Normal    32 degrees C
DIMMB1 Temp        N/A    Not Present
DIMMB2 Temp        Normal    32 degrees C
FAN1            Normal    2300 R.P.M
FAN2            N/A    Not Present
FAN3            N/A    Not Present
FAN4            Normal    2200 R.P.M
FANA            Normal    3200 R.P.M

Anywhere (the homedir of root being a prime candidate, "hidden" from NAS users). Then create a "postinit" task under Tasks>Init/Shutdown Scripts.
It is not self-evident, but it's in the thread.
