In the other thread I suggested to drop the -o cause you weren't using options, but in this thread you are.
However the syntax for mount is : mount [flags] DEVICE NODE [-o OPT,OPT]
So your command should be:
mount -t nfs 192.168.2.4:/mnt/array1/Buffalo ./test -o nfsvers=2,rsize=32768,wsize=32768,timeo=14,intr,pr oto=tcp
But, I doubt that nfsvers, rsize, wsize, timeo and proto are valid options for "mount", I would just use:
mount -t nfs 192.168.2.4:/mnt/array1/Buffalo ./test
