Unable to create a pool of 2 equal disks

Hi I am new to TrueNAS. I have it installed on an old 2010 PC in BIOS mode. I am able to login to the TrueNAS dashbord from another PC. Version is TrueNAS-13.0-U6.2 stable. when I want to create my first pool I get a failure. See below in this post.
Any suggestions how to solve this problem?

Need more details like all hardware. You can browse different threads while waiting for answers so your forum trust level goes up and gives you more posting rights.

Details for the PC:
Motherboard Gigabyte GA-EX58-UD5
Processor Intel Core I7 920 @2,67 Ghz
Memory DDR3 16GB 1600 XMS Kit3 CL7 Support i7
Hard disk Western Digital 1TB 32MB 7200 Rpm
Hard disks 2x AFBS25 Seagate Barracuda 7200.14, 2 TB
SSDsData 2x Samsung 850 EVO, 250 GB, Solid State Drive

I want the 2 Seagates in a mirrorpool
Do I need to give more technical details?

I forgot to mention that TrueNAS is running from a USB drive, a Kingston DataTraveler 160 16GB

What I see when I start TrueNAS is an error:

I dont know if it is an origine of the problem I have.

Are you on a profile with admin permissions? From the errors, it looks like a permission issue to me.

can you describe the error when starting TrueNAS, when it happens or provide screenshots? You can use Snipping tool if on Window

I dont know what you mean. TrueNAS is exclusively started on the old desktop so Windows or another OS isnt running. Then when it runs I start on another PC in the browser the TrueNAS dashboard. Do I need special permissions on the PC with the dashboard?

When you login in to the GUI on the web, what user are you using? root?

When TrueNAS boots from the USB on the old PC it generated the error. I dont know exactly at what stace of the proces it is. I have made a photo when it occurs.

Maybe you have an idea at what stace in the proces it is.
By the way I appreciate the questions very much.

Yep I am using root as user

Just ignore those VMware errors.

Do you have any pools or VDEVs created at this point. HD or SSD?
Are all your disks showing in the GUI?

Ok.
No I have not. When I try that I get the error. See the screenshots.


Could it be a services problem? All the services are stopped except the S.M.A.R.T. service

That is normal. Try going to the disks page and running a long smart test on that disk.

Ok, thx. I will do that and that will take some time. So I close the shop for now and report back tomorrow

Did a lot of a heck of work on the old PC. Reset the cmos on the motherboard. Changed some settings in the Bios and that gave me a lot of work there after to get the PC booting and running again. Removed one disk from the. Installed TrueNAS new once again on the USB stick. After that I was able to create 2 pools from the four disks in the PC. So now I need to do the rest to make them accessable and share them on the network.

What the problem exactly was I dont know. Only the result counts as they say.
Thx for the support.
