Some of the stuff you want can be found here:

root at shark:~# file -s /dev/ufs/home 
/dev/ufs/home: Unix Fast File system [v2] (little-endian) last mounted on /home, volume name home, last written at Fri Dec 26 06:33:07 2008, clean flag 0, readonly flag 0, number of blocks 13631488, number of data blocks 13202246, number of cylinder groups 145, block size 16384, fragment size 2048, average file size 16384, average number of files in dir 64, pending blocks to free 4, pending inodes to free 0, system-wide uuid 0, minimum percentage of free blocks 8, TIME optimization

You probably want the clean flag (which is 0 for me because that device
node is mounted).

HTH,
