dumplfs
DUMPLFS(8) BSD System Manager's Manual DUMPLFS(8)
NAME
dumplfs -- dump file system information
SYNOPSIS
dumplfs [-adiS] [-b blkno] [-I blkno] [-s segno] filesys | device
DESCRIPTION
dumplfs prints out the file system layout information for the LFS file system or special device 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.
The following flags are interpreted by dumplfs.
-a Dump the contents of all superblocks, not just the first. Superblocks appear in the dumplfs output with the segment containing them.
-b Use the block specified immediately after the flag as the super block for the filesystem.
-d Check partial segment data checksums and report mismatches. This makes dumplfs operate much more slowly.
-I Use the block specified immediately after the flag as the inode block containing the index file inode.
-i Dump information about the inode free list.
-S Dump information about the segment table.
-s Add the segment number immediately following the flag to a list of segments to dump. This flag may be specified more than once to
dump more than one segment. The default is to dump all segments.

The dumplfs command appeared in 4.4BSD.
