Creating zpool on NVMe Disks takes forever

[Michael Fuckner]

Hi,

I have two NVMe PCIe Cards in a System running 10.1-p5.

root at s4l:~ # ll /dev/nv*
crw-r-----  1 root  operator  0x63 Feb 19 08:51 /dev/nvd0
crw-r-----  1 root  operator  0x67 Feb 19 08:51 /dev/nvd1
crw-------  1 root  wheel     0x30 Feb 19 08:51 /dev/nvme0
crw-------  1 root  wheel     0x5c Feb 19 08:51 /dev/nvme0ns1
crw-------  1 root  wheel     0x31 Feb 19 08:51 /dev/nvme1
crw-------  1 root  wheel     0x62 Feb 19 08:51 /dev/nvme1ns1

I can partition/format the disks with UFS and access them without 
issues, but I can't create a zpool. It simply takes forever when I enter 
the following command:

zpool create tank0 mirror nvd0 nvd1


Any idea what to check?

Regards,
  Michael!
