You can use nvme-cli to check your NVMe disks. To install nvme-cli, run

On Ubuntu/Debian

sudo apt-get install -y nvme-cli

On RHEL

sudo yum install nvme-cli

To list of NVMe drives, use

nvme list

Example

[root@server52 ~]# nvme list
Node             SN                   Model                                    Namespace Usage                      Format           FW Rev

[root@server52 ~]# 

To find smart data, run

nvme smart-log DEVICE_NAME_HERE

Example

[root@server52 ~]# nvme smart-log /dev/nvme0n1
