I was able to find a solution now: root@TOASTY:~# nvme format /dev/nvme0n1 You are about to format nvme0n1, namespace 0x1. Namespace nvme0n1 has parent controller(s):nvme0 WARNING: Format may irrevocably delete this device's data. You have 10 seconds to press Ctrl-C to cancel this operation. Use the force [--force] option to suppress this warning. Sending format operation ... Success formatting namespace:1 root@TOASTY:~# fdisk -l /dev/nvme0n1 Disk /dev/nvme0n1: 13.97 TiB, 15362991415296 bytes, 3750730326 sectors Disk model: NETAPPX4028WCOFB15TNTE Units: sectors of 1 * 4096 = 4096 bytes Sector size (logical/physical): 4096 bytes / 32768 bytes I/O size (minimum/optimal): 32768 bytes / 32768 bytesAfter that to be able to format the nvme: open Settings in GUI and go to Utilities/Unassigned devices common settings: set destructive mode to enabled Main menu: Format disk reset destructive mode to disabled the nvme is usable now.

with hdparm i see the following: root@TOASTY:~# hdparm --verbose /dev/nvme0n1 /dev/nvme0n1: APT: No idVendor found -> not USB bridge device outgoing cdb: 85 08 0e 00 00 00 01 00 00 00 00 00 00 40 ec 00 ioctl(fd,SG_IO): Inappropriate ioctl for device outgoing cdb: 85 08 0e 00 00 00 01 00 00 00 00 00 00 40 a1 00 ioctl(fd,SG_IO): Inappropriate ioctl for device HDIO_DRIVE_CMD(identify) failed: Inappropriate ioctl for device readonly = 0 (off) readahead = 256 (on) outgoing cdb: 85 08 0e 00 00 00 01 00 00 00 00 00 00 40 ec 00 ioctl(fd,SG_IO): Inappropriate ioctl for device outgoing cdb: 85 08 0e 00 00 00 01 00 00 00 00 00 00 40 a1 00 ioctl(fd,SG_IO): Inappropriate ioctl for device HDIO_DRIVE_CMD(identify) failed: Inappropriate ioctl for device geometry = 0/64/32, sectors = 0, start = 0 root@TOASTY:~# hdparm -g /dev/nvme0n1 /dev/nvme0n1: geometry = 0/64/32, sectors = 0, start = 0

it shows invalid argument for the netapp disk (nvme0n1). There is another M2 SSD directly on the motherboard (WD_Black) and fdisk -l works for this one: root@TOASTY:/dev# fdisk -l /dev/nvme0n1 fdisk: cannot open /dev/nvme0n1: Invalid argument root@TOASTY:/dev# fdisk -l /dev/nvme1n1 Disk /dev/nvme1n1: 1.82 TiB, 2000398934016 bytes, 3907029168 sectors Disk model: WD_BLACK SN850X 2000GB Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x00000000 Device Boot Start End Sectors Size Id Type /dev/nvme1n1p1 2048 3907029167 3907027120 1.8T 83 Linux

I cannot connect these devices directly to the motherboard, because of the SFF-8639 interface, the mainboard does not have such an interface and therefore I have to use the PCIe card to connect these NVMe-SSDs. What do you exactly mean with: "not being correctly detected"? Some Netapp SSDs (at least the SAS_SSDs) are formatted with 520 byte sectors, instead of 512 bytes. And they need to be re-formatted with sg3_utils tool. Don't you think, this could be the reason here as well? But that is just an assumption....maybe I'm completely wrong.

Hi JorgeB diagnostic logs are attached. thanks for your help sandsturm toasty-diagnostics-20260330-2135.zip

Hi I want to add 4 nvme SSDs into my unraid system. The nvme SSDs are from a Netapp system. I used to have Netapp SSDs attached via SAS and there i had to change the sector size with sg_format according to: https://forums.unraid.net/topic/71348-sas-drive-520-sector-size/#findComment-693536 . This worked fine for SAS SSDs, but it seems that this way does not work with NVMe SSDs. I attached the nvme SSDs with this pci card: PCIE 4.0 auf 4x U.2 Erweiterungskarte SFF-8639 SFF-8643 NVME PCIE x16 SSD Adapter | Fruugo CH and with theses cables: SFF-8643 to SFF-8639 Connector SFF-8639 with 15Pin Power Adapter Cable Data Transmission Cable for PC Servers | Fruugo CH After I changed the pci card to use x4x4x4x4 (bifurcation) on the x16 slot on my motherboard, I was able to see the SSDs in unraid , see this screenshot: Upload and share screenshots and images - print screen online | Snipboard.io I cannot mount these devices nor can I use them in a pool. I assume, I have to format them as well, but don't know what tool I have to use. Does anyone has experience on this topic? thx, sandsturm

Hi I want to move an existing ZFS Pool with 4 SSDs to new hardware. Questions: is this possible? If yes, Is it the same as for disks in an array (just move it to the new hardware) or do I have to pay attention on something? thx, sandsturm
