dumpfs - dump file system information
dumpfs [filesys | device]
dumpfs prints out the super block and cylinder group information for the
file system or special device specified. The listing is
very long and
dumpfs is useful mostly for finding out certain file system
such as the file system block size, minimum free space percentage, and
the file system level that can be upgraded with the -c option of
fsck_ffs(8). All of this information can be found within
the first twenty
lines of the output.
disktab(5), fs(5), disklabel(8), fsck(8), fsck_ffs(8),
