Cant create Pool on TrueNAS Scale (it does work on TrueNAS Core under same Hardware)

I can confirm the issue on a new fresh trueNAS SCALE install (21.08-BETA.1) when I would like to create a pool with two disks with mirroring :

 
And my disks are not protected :

The problem seems random, because after several attempts it worked without explanation.

I am also observing this issue: got 3 brand new Seagate IronWolf Pro 4TB SAS drives installed them into QNAP-653D, booted into TrueNAS SCALE from the USB stick and cannot create the pool via Web UI.  The behavior matches exactly what is described by previous reporters.  None of the disks are protected and I believe this issue needs to be re-open and investigsted.  This is output from my system:

and this is the error I am getting in the Web UI:

Please let me know if you need any additional info about the system.

I had the same issue (my drive did not have the security bits set), and creating the pool manually on the commandline then importing it in truenas worked. Note, I had to restart my server after manually creating the pool for truenas to see the new pool to import.

New Dump File

Hi Caleb, sadly reformating does not work (I attahced a new dump file). Also i also think this is not working as expected (at least in compartission with TrueNAS Core. There i achieve to create the pool directly from the GUI without warryng about wiping and reformating on the first try consistently <I have 9 of this blades, all with trueNAS core except the one i am now reporting. FreeBSD is handling this drives in a better and simpler way)

reformatting:

error afterwards while trying to create the pool:
