Faulty psu - Do I need to reinstall?

[John Eccles]

Hi all,
It's my first post so go easy on me.

I recently installed Freenas 9.3 on an ASRock C2750D4I with a Silverstone 300W psu (SST-ST30SF SFX).
It has 32Gb of Crucial ECC ram and the OS is on a single ssd.

I've had a few random issues over the last couple of days. Mainly with the Transmission plugin stopping and then Freenas reporting that it's not installed. Connecting to the board through ipmi showed that there have been dozens of occasions when the ATX 5v supply has dropped too low. I'm assuming this is the source of my problems and am having it replaced.

My question is whether the OS is likely to have suffered any corruption. Is there any way to check or should I reinstall and re-import the pools?

Thanks for your help,
John

Scrub the boot pool (which the system does periodically by default anyway). If there are no errors, you're good to go.

Guessing you mean an ASRock, not an ASUS?

Might want to describe your PSU and platform a little more. A 300W PSU is really only going to work out if you have a maximum of about two drives.

Thank you both for your replies.

@jgreco - yes I did mean ASRock (sorry), and I made the rookie mistake of underestimating the power requirements. I have eight drives. I've now read the page you referred me to. I can swap it for the Silverstone Strider 600w psu (50A on 12v rail). That would seem to be powerful enough if I've added everything up correctly. The system is as stated plus a 2 port Intel nic and two fans.

No worries, we could tell from the part number, just reducing possible confusion for the rest of the audience. I've edited your original post to correct it.

Let me just say that you're very lucky that you bothered to follow up on this "little warning sign." It's impossible to know the reality of your actual system and what's truly transpired, but your old PSU may be giving you signs that you've done some damage to it, and you are strongly encouraged to disconnect that PSU and never attach it to anything you deem valuable or important again. It might be fine. It might not. I view PSU's as cheap components that I have to be able to trust because I might be hooking up thousands of dollars of silicon and platters to them. With a little luck, there's a very good chance that you caught this before damage was done to any of the rest of the system.

Please do follow up and let us know if your "little warning sign" clears up with a properly sized PSU. ZFS will take care of your data, so as long as ZFS doesn't complain about the boot device after it scrubs it, you should be good to go.

I will post in a week or so to give the system a chance to flag up any errors.

Thanks for your advice again, it's much welcomed and respected

Hi all,
it's been a couple of weeks or so since I changed the psu to the Silverstone Strider 600w and I'm happy to report that all is well. A scrub of the boot pool showed no error and all of the issues have gone away and I'm very pleased with the way the system is running.

Thanks again for your help,
Regards,
John
