NVMe drives not displaying in WebUI

[bryan_v]

Hi, I just installed TrueNAS Scale on bare metal to replace my old Ubuntu NAS install, however my NVMe drives are not making it through to the WebUI, but are detected and mountable in the underlying Debian system. I need some help in determining what are the common troubleshooting steps in TrueNAS scale to determine at what point the drives are blocked from showing up in the WebUI under "Storage">>"Disks", and hence being able to create pools.
Essentially:

• There are two NVMe drives
  • 1st drive is a Samsung 970 Pro 512GB installed into the M2_2 slot which is a PCIe 3.0 x2 slot
    • Drive is detected correctly in BIOS
    • Drive shows up correctly in 'lsblk' and 'lspci'. Debian detects the device as '/dev/nvme1'
    • Drive currently has a single ext4 partition (to be migrated if it can be mounted, even in just read only)
    • Can be manually mounted in Debian via 'mount', detected by Debian as '/dev/nvme1n1'
  • 2nd drive is an Intel P4510 3.84TB mounted on an 2x U.2 adapter card with an PCIe 3.0 x8 uplink, installed in PCIE_4 which is configured for x4x4 operation.
    • Drive is detected correctly in BIOS
    • Drive shows up correctly in 'lsblk' and 'lspci'. Debian detects the device as '/dev/nvme2'
    • Drive currently has a single ext4 partition (to be migrated if it can be mounted, even in just read only)
    • Can be manually mounted in Debian via 'mount', detected by Debian as '/dev/nvme2n1'.

Screenshots of the WebUI and lsblk are attached at the bottom.

System Specs:

• ASRock Rack X470D4U-2T (configures with x4x4x4x4 PCIe Bifurcation)
• Ryzen 3600
• 2x 32GB RAM @3200MT/s
• Boot drive: Samsung P981a w/256GB in slot M2_1 (PCIe 2.0 x4)
• Network: 2x 10GBase-T via onboard X550

Looking forward to figuring this out and getting ZFS going.

Cheers,
Bryan

You appear to want import data, not create pool. Because the NVMe devices have a partition the GUI may consider them in use.

Import is done through;
Datasets -> Import Data

However, you have no where to migrate the data. You've listed both as having data you want copied off.
