DUMPLFS(8)              NetBSD System Manager's Manual              DUMPLFS(8)


NAME

     dumplfs - dump file system information


SYNOPSIS

     dumplfs [-a] [-b blkno] [-I blkno] [-i] [-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 de-
     tailed.  This command is useful mostly for finding out certain file sys-
     tem 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.  Su-
             perblocks appear in the dumplfs output with the segment contain-
             ing them.

     -b      Use the block specified immediately after the flag as the super
             block for the filesystem.

     -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      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 seg-
             ments.
