DESCRIPTION
Thedumpfs
utility prints out the super block and
cylinder group information for the file system or special device specified,
unless -m
is specified. The listing is very long and
detailed. This command is useful mostly for finding out certain file system
information such as the file system block size and minimum free space
percentage.
If -m
is specified, a
newfs(8) command is printed that can be used to generate a new file
system with equivalent settings.
