I replaced the disk Claude identified, ran an error-correcting sync, and then a non-correcting sync came back clean.

What would you try first?

Do you see anything else in my diagnostics that could be causing this issue?

What I've tried: Replaced SATA power and data cables to parity drive, which was showing ATA errors in syslog. ATA errors no more, but still getting parity sync errors. Ran a correcting parity check - corrected 1M+ errors, but new errors appeared immediately on the next non-correcting check. Reseated all RAM and removed the 7th DIMM - went from 7 DIMMs (asymmetric) to 6 DIMMs in 3 matched pairs. Mobo is Supermicro X10SRi-F. Claude noted the errors are deterministic - same starting sector (8,637,552) with contiguous 8-byte stepping pattern, identical across every parity check regardless of RAM configuration. This reproducibility across reboots and RAM changes ruled out RAM as the cause. No way to verify if this is just an AI hallucination. Claude identified disk5 (TOSHIBA HDWE140 874DK07HF58D, sdw) as suspect - SMART report shows 38 logged ICRC errors, UDMA CRC Error Count of 30, and 57,805 power-on hours. Every other drive on the same mpt2sas_cm1 controller shows 0 UDMA CRC errors, isolating the issue to sdw specifically rather than the controller or cabling. Current theory: sdw is intermittently returning corrupted data over the SATA interface due to CRC errors, causing deterministic parity mismatches at the same sector region on every check. The drive is also extremely aged at 57,805 hours. Planned next steps: Use Unbalance to move all data off sdw, unassign it from the array, run a fresh correcting then non-correcting parity check to confirm whether errors clear. If clean, replace sdw with a new drive. If errors persist after sdw is removed, further investigation needed. Am I missing something? ptero-diagnostics-20260503-1818.zip

No. I'm going to give in to MailStore soon.

After much tinkering, here is what I've learned about trying to automate fan control on a Supermicro X10SRI-F: For context, I have 5 Arctic P12 fans plugged into fan connectors 1 through 5. My CPU cooler, a Noctua NH-L9i, is plugged into the FAN_A connector. I was never able to control the CPU fan with the IPMI plugin. However, I was able to partially control fans 1 through 5. But after enabling fan control, all of the fans would spin to max after 2 minutes. According to ChatGPT, this is because the BMC Watchdog Timer changes BMC fan control back to auto. Long story short, I had to install the IPMCFG utility and control the fans with a script, which I've attached. It's very important to note that if you set the P12 fans below 20% RPM, the BMC fan mode will revert to auto. If you try to set the Noctua fan (NF-A9x14) below 30%, the BMC fan mode will revert to auto. The script runs every minute and re-asserts the BMC fan mode to manual each run. This board only has 2 fan control channels; one for fans 1 through 5, and one for Fan A. I'm sorry I couldn't figure out how to use the plugin. Hopefully this info and script will help others. I have not yet tested the script under load, so use at your own risk. I'll update this post if I modify the script or find any bugs. @JorgeB @SimonF x10sri-f_fan_control.sh

When the following was logged,... 2025-04-11 08:23:59 Fan:Temp, FAN1234( 2%):HDD Temp(Spundown), FANA( 2%):CPU Temp(28C) ...my drives were all spundown (as indicated). And yet, the fans cooling them were spinning pretty fast (not 2%) with sensor readings of 1700 RPM.

What is weird is that even though it says the fans are spun down, these are the actual sensor readings.

Do these screenshots help, @SimonF and @JorgeB?

After removing the network connection, the Fan Settings section under Fan Control returned. However, I am not able (or cannot figure out) how to disable the Virtual Machine Override. For now, I have it set to Supermicro X10 as my board is an X10SRI-F. As I'm sure you're aware, I had to set Fan Control to No to be able to remove the network connection. Before I set Fan Control back to Yes, All of the fans would spin down and then up continuously. This behavior stopped after I set Fan Control to Yes. With Fan Control set to Yes, all of the fans' speeds seem to be pinned. FANA cools my CPU and FAN1-5 cool my HDD array drives. Here's what that looks like on the Sensors page. Here are my Fan Settings. Here are the sensor settings for all my fans.

Not to pile on... but this is also happening: I know there is much discussion about the Noctua fans. Is the fix to alter these settings?

Just the Fan Settings section is blank. Advanced is enabled. IPMI fan mode set to optimal, but I've also tried standard and full.
