I see there are multiple storage fencing options available through SCSI, i.e. either use stonith or scsi\_fencing etc.  
Looking if something similar already there with NVMe based storage ?

I guess you mean NVMe-oF . If the LUN supports persistent reservations , you can use fence\_scsi. Of course, you can use sbd - which requires that there is no host-based mirroring on it and nothing more. It is used by default via the ha-cluster-init bootstrapping script.
