Same issue here. No matter how may times I delete partitions, clear disks or issue blkdiscard, the existing nfs partition on the first drive won't be replaced by the BTRFS one I create and in the second one, no partition is created altogether (same BTRFS).
As the title states.
Unraid is unable to see *any* drive directly connected to the card.
-BIOS detects all the drives
-card boots fine on another machine with just OS drive attached on it
-iommu=pt is enabled in boot parameters
-virtualization on or off on the motherboard makes no difference at all.
-card is in supported list https://wiki.unraid.net/index.php/Hardware_Compatibility#PCI_SATA_Controllers
Diagnostics attached.
