Truenas randomly shutting down

[Samuel Tai]

Yeah, that looks like some sort of protection circuitry kicking in, and cutting power to the board.
What are the exact models of the Seagates and HGSTs for disks da14-20? This could be one of your Icy Docks is pulling too much power.

 

[NugentS]

SMR or CMR?

 

[PlasmPlayer]

Here are i believe all the modelss
Seagate ST500LM021-1KJ15 - 7200 RPM
Seagate ST500LT012-1DG14 - 5400 RPM
HGST HTS545050A7 - 5400 RPM
HGST HTS725050A7 - 7200 RPM
WDC WD5000LPLX-6 - 7200 RPM

 

[Samuel Tai]

None of those appear to be SMR drives, according to https://www.truenas.com/community/resources/list-of-known-smr-drives.141/. However, it is telling that all the drives with timeouts appear to be on one IcyDock. IcyDock isn't known to have reliable multi-drive bays.

 

[PlasmPlayer]

It's going to suck if it is the IcyDock Drive Bay causing problems. That is what this server was built around. Is there a way to tell which one is causing problems? i can try to warranty it

 

[Samuel Tai]

Whichever one is hosting da14-da20.

 

[PlasmPlayer]

Sounds good. Does truenas keep the same drive names after each reboot? I keep a spreadsheet of where each drive serial number is located.

 

[Samuel Tai]

No, drive devices aren't guaranteed to be stable. Look in the GUI, under Storage->Drives for the relevant serial numbers.

 

[PlasmPlayer]

thats going to make it difficult to figure out which one is causing issues. I might open up the chassis and reseat everything in case a cable is not fully seated.

 

[NugentS]

According to Seagate's website all their 2.5" drives are SMR

CMR and SMR Hard Drives | Seagate UK

See the list of recording technology utilised on our internal hard drives

www.seagate.com

The WD might be SMR (50:50)

The HGST are probably DM-SMR (maybe)

I think we can safely say its highly unclear - but not looking good

[I would really love to be wrong on this]

 

[PlasmPlayer]

well that sucks, just about all of them are seagate. could that cause these errors from the video and causing the system to shut down?

 

[PlasmPlayer]

Did a little google fu and it looks like the seagate thin drives are part of the momentus line and are perpendicular drives which is the same as CMR

Perpendicular recording - Wikipedia

This is pretty useful information. but this leaves the question if its the hard drive encloser causing the timeouts.
I am learning a lot about hard drives and hardware today

 

[pschatz100]

There have been lots of good comments here. I would also like to add that gaming boards have lots of features not compatible with TrueNAS and you should turn them all off in the bios: audio, enhanced networking features, any overclocking or system tuning, etc. For good measure, I would also temporarily disable all power-saving features. If the system runs better, then you know something was causing a conflict.

and 2 HBA cards connecting up to 32 2.5 inch hard drives.

While 2.5" drives aren't as hard on a PSU as 3.5" are, you're still potentially short. If you'd like to learn how to properly design a PSU for NAS, please look at

Proper Power Supply Sizing Guidance

I've seen about 1,000 threads like this one where people decide that they can power a dozen hard drives off a 360 watt supply. DO NOT DO THIS. I've seen another 1,000 threads where people decide to buy the cheapest power supply that they can find. DO NOT DO THIS. Your NAS lives or dies by...

I tried this calculator here

Power Supply Calculator - The most accurate PC wattage calculator

Calculate the true power usage of a PC. Check how many watts your computer is using when idle or in full load. This online PSU calculator tells you all you need to know.

powersupplycalculator.net

with 32 drives and the 3 SSDs, it says the recommended PSU size should be 331 Watts
The datasheet for the Seagate drives says the peak power draw when starting up is 5 watts and run at usually just under 2 watts

Generic PC power supply calculators generally do not make proper allowance for spinup current. 5 watts times 32 drives is 160 watts all on its own, so clearly that's full of crap. Please go back and look at the post I pointed you at, which will teach you the correct way to calculate this and ALSO explains WHY it is the correct way to calculate it.

I read through a bit of that post and information from 45 drives.
So I'm guessing I should upgrade to a 1000 watt PSU? If so, I was looking at the Seasonic PRIME GX-1000

 

[Samuel Tai]

It's not just the power headroom on the PSU you need to look at, but also the amp delivery on the rails.

 

[Samuel Tai]

Your CPU is way overkill for this application. In fact, you could swap your i7-4790K (88W TDP) for an i5-4460T (35W TDP) and still have lots of CPU in reserve for jails and VMs. Disable your audio system and any automatic overclocks to gain additional power headroom.

 

[PlasmPlayer]

The 12v rail can support 996 watts.
The 4790k is left over after upgrading my main computer. I plan on getting a e3-1240l v5 setup when funds are available. 25watt CPU with also 8 threads. Should be more than enough for my needs
