IMO this is the problem. For whatever reason there are still some UUID
on other disks.

Did you used the command wipefs -a on all disks and partitions?
Maybe also use dd and write some MB of zeros onto the disks. There may
be signatures of soft raid and GPT tables at the end of the disk. 

In your format.log we only see sdb. So another FAI run must have
written to other disks.

Also check $disklist in /tmp/fai/variables.log
