# file -s /dev/rwd0e
/dev/rwd0e: Unix Fast File system [v2] (little-endian) last mounted on /usr, 
last written at Sun May  5 08:05:50 2013, clean flag 2, readonly flag 0, number 
of blocks 20480040, number of data blocks 19855038, number of cylinder groups 
217, block size 16384, fragment size 2048, average file size 16384, average 
number of files in dir 64, pending blocks to free 0, pending inodes to free 0, 
system-wide uuid 0, minimum percentage of free blocks 5, TIME optimization

This example is done on NetBSD/amd64 current.
I believe "Unix Fast File system [v2]" means FFSv2.
