DUMPFS(8)						    BSD System Manager's Manual 						 DUMPFS(8)

NAME
dumpfs -- dump file system information SYNOPSIS
dumpfs [-acFijmsv] filesys | device [...] DESCRIPTION
dumpfs prints out detailed information about the specified filesystems. Options: -a Print details from each alternate superblock. -c Print details of each cylinder group. -F Dump a file system image from a file, not a special device. -i Print details of each allocated inode. -j Print details of the WAPBL journal. -m Print details of the cylinder group summary. -s Print details of the superblock. -v Be even more verbose. If none of -a, -c, -i, -j, -m, or -s are given, then dumpfs defaults to -cmsv. 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 the -c option of fsck_ffs(8). All of this information is output by dumpfs -s. SEE ALSO
disktab(5), fs(5), disklabel(8), fsck(8), fsck_ffs(8), newfs(8), tunefs(8) HISTORY
The dumpfs command appeared in 4.2BSD. The -a, -c, -i, -m, and -s options, and the inode dump were added for NetBSD 2.0. The -j, option was added for NetBSD 6.0. BSD

NAME
dumpfs -- dump UFS file system information SYNOPSIS
dumpfs [-f] [-l] [-m] filesys | device DESCRIPTION
The dumpfs utility prints out the UFS super block and cylinder group information for the file system or special device specified, unless the -f, -l or -m flag 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 -f is specified, a sorted list of all free fragments and free fragment ranges, as represented in cylinder group block free lists, is printed. If the flag is specified twice, contiguous free fragments are not collapsed into ranges and instead printed in a simple list. Fragment numbers may be converted to raw byte offsets by multiplying by the fragment size, which may be useful when recovering deleted data. If -l is specified, the pathname to the file system's container derived from its unique identifier is printed. If -m is specified, a newfs(8) command is printed that can be used to generate a new file system with equivalent settings. Please note that newfs(8) options -E, -R, -S, and -T are not handled and -p is not useful in this case so is omitted. Newfs(8) options -n and -r are neither checked for nor output but should be. The -r flag is needed if the filesystem uses gjournal(8). SEE ALSO
