can you link what exact card you’ve bought?
the ASM1166 is a 6-port chipset, not 10-port. which brings the possibility you’ve bought a card with port-multiplier chips.
Your log also has lines like [ 3.449927] ata2.00: ATAPI: QEMU DVD-ROM, 2.5+, max UDMA/100 suggesting you may be running this in on a hypervisor which can be risky if not done correctly. (Proxmox in particular has been known to silently import TrueNAS pools before starting the TrueNAS VM…)
not sure what you mean by adding locomotives… but please describe your setup.
