dump file system information
-m] filesys |
prints out the super block and cylinder group
information for the file system or special device specified, unless
is specified. The listing is very long and
dumpfs is useful mostly for finding out
certain file system information such as the file system block size, minimum
free space percentage, and the file system level that can be upgraded with
-c option of
fsck_ffs(8). All of this information
can be found within the first twenty lines of the output.
-m is specified, a
newfs(8) command is output that can be
used to generate a new file system with equivalent settings.
