SOLVED From dream to nightmare: NAS usage impossible and problem unknown

[WI_Hedgehog]

This morning I brutally unplugged 7 out of 10 HDs to see if the system would work with the SAS controller still plugged in. I would have unplugged another one if the situation was still the same and then unplugged the SAS controller. The pleasant surprise: the system works and is stable. The created pool is finally stable and fully functional. I must therefore thank you for making me understand the problem in the configuration of my machine. Now I have to buy a power supply to match (I think I'll get a Seasonic 850/1000 W). Thanks again.

Awesome, I'm extremely happy for you. You really do have a great foundation.

Building, Burn-In, and Testing your FreeNAS system

I've been meaning to post some guidance here for a while now. We frequently see people come to the forums with hardware problems that should have washed out in the system build process, but since many of the users here are DIY'ers without professional experience building servers, it goes from...

Hard Drive Burn-in Testing

@jgreco did a nice system build/test/burn-in guide here, but I (and many others) found the details a bit lacking in the hard drive section. He mentions S.M.A.R.T. tests, but doesn't go over how to run them, or how to view the results, etc. and...

I usually use the solnet array for burn-in.

Back in the late '90's, I was managing a bunch of large whitebox storage servers. For the largest of these, I had the pleasure of building and deploying a massive storage server, 8 shelves of 9 drives each, Seagate ST173404LW 73GB drives, a...

Excellent choice. Seasonic power supplies have a solid reputation here.

I purchased and am waiting to receive the Seasonic Prime Ultra Platinum 1300 W (80 Platinum). However, I have a small doubt: the 5 V section is declared for 25 A (125 W). I have not found other ATX format power supplies with more power on 5V. Will that be enough power in your opinion?

That should be plenty.
