On a fresh install of TrueNAS Scale 25.10.1 - Goldeye
installed on mirrored 2 SSD (sdi, sdj)
Under Pool Creation Wizard create a data pool (RAIDZ or dRAID) with 8 other HDD (sda, sdb, sdc, sdd, sde, sdf, sdg, sdh)
Fail with :
Error: topology
Disks have duplicate serial numbers: ‘"\x03D\x00D\x000\x000\x000\x000\x000’ (sdi, sdj).
How do you have them attached? Post full hardware details. We can’t guess at your setup and can only go off information provided in your post.
Welcome to the forum !
My wild guess would be, that (at least some.of…) your drives are attached externaly via USB…
If so, try to use the search for “topology”, and you will find some (even recent) threads about this topic, with some details what might be the problem, and with some (light …) bashing, that USB-attached drives are (mostly) a bad idea…

Can you post your hardware setup like the DETAILS section under my post. What are the USB attached drives, make, model? Are they USB thumb drives or actual SATA drives attached over USB. To temp bypass, you can remove a drive from the mirror boot pool and make it a single. Just make sure you have a backup of your current, system configuration. It’s easy to reload the OS / boot drive, upload the config and be back to ‘normal’
Check your motherboard documentation for what is supported. How are all the 8 HD attached?
