SOLVED Mirror (Raid 1) not available as choice for new pool

[NanoBot77]

Hi all,

I was able to install on my Thinkcentre M81 SFF the TrueNAS 12 OS. Now I have two HDD (SATA) with 2TB. During pool creation I was not able to choose Mirror (RAID 1). See picture attached. Do you have any suggestion? Bios is set to AHCI.

Regards

Ok, the solution is as stupid as simple: Just fill out a name for the pool.
