Hello,

 

    This is my first post and hoping someone might be able to point me in the right direction since this is such a great community.  I updated my Unraid OS (been running well for over a year) the other day and everything seem to go OK except its no longer is seeing my NVME drive I use for my Windows VM (used SpaceInvader One instructions).  Still seeing the NVME drive in BIOS so thinking its something on the Unraid config side.  I went through the syslog and not seeing anything.  I checked the System Devices and its seeing the controller "[144d:a808] 02:00.0 Non-Volatile memory controller: Samsung Electronics Co Ltd NVMe SSD Controller SM981/PM981/PM983" but nothing in the vfio.log...  Attached is my dianostics file and really appreciate any recommendations!

 

Thank You,

The NVMe device is bound to vfio-pci, unbind it, and also check that Asmedia controller, in case it's also bound by mistake:

 

02:00.0 Non-Volatile memory controller [0108]: Samsung Electronics Co Ltd NVMe SSD Controller SM981/PM981/PM983 [144d:a808]
    Subsystem: Samsung Electronics Co Ltd SSD 970 EVO/PRO [144d:a801]
    Kernel driver in use: vfio-pci
    Kernel modules: nvme
03:00.0 SATA controller [0106]: ASMedia Technology Inc. ASM1061/ASM1062 Serial ATA Controller [1b21:0612] (rev 02)
    Subsystem: ASMedia Technology Inc. ASM1062 Serial ATA Controller [1b21:1060]
    Kernel driver in use: vfio-pci
    Kernel modules: ahci
