I have a number of Gentoo Linux servers running the latest available version of net-snmp and i have tried with a number of basic and advanced snmpd.conf configurations and have yet to get an NVME device to be discoverable.

Edit: Upon further investigation, this issue strictly concerns F2FS formatted partitions and has nothing to do with NVME drives.
