You are reading a document for something which is not glusterfs.

No. You are reading documentation for something completely different: a pair
of machines synchronised at the block level using DRBD, in a master/slave
configuration (that is: all writes must be made on the master side, and the
block changes are replicated a la RAID1 but over a network).
I suggest you ask a different question: "can I have failover between two
gluster NFS servers without getting stale filehandles?"
I don't know the answer to that myself, but I have seen messages which
suggests others may have it working:
