Subject: NVMe disks are not available with lsblk
Message-ID: <24c11b7c42c0958f813aa396c6cd85c3@linux.vnet.ibm.com>

Hi All,

Somehow with CONFIG_NVME_MULTIPATH enable(4.16.0-rc1), one of my NVME 
device is not showed up with lsblk command.


I am not familiar with CONFIG_NVME_MULTIPATH enable. I tried to enable 
multipath in system but still not show up.

For example,/dev/nvme1 device is showed up in nvme list but not with 
lsblk.

Anyone saw the similar issue? Any suggestion for debugging this issue?

Thanks,
Wendy
