DUMPFS(8) BSD System Manager's Manual DUMPFS(8)
NAME
dumpfs - dump filesystem information
SYNOPSIS
dumpfs [filesys | device]
DESCRIPTION
dumpfs prints out the super block and cylinder group information for the
filesystem or special device specified. The listing is very long and de-
tailed.
dumpfs is useful mostly for finding out certain filesystem information
such as the filesystem block size, minimum free space percentage, and the
filesystem 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.
