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

NAME
     resize_lfs -- resize a mounted log-structured filesystem

SYNOPSIS
     resize_lfs [-v] [-s new-size] mounted-file-system

DESCRIPTION
     resize_lfs grows or shrinks a mounted log-structured filesystem to the specified size.
     mounted-file-system is the name of the filesystem to be resized, and new-size is the desired
     new filesystem size, in sectors.  If new-size is not specified, resize_lfs will default to
     the current size of the partition containing the filesystem in question.

     When growing, the partition must be large enough to contain a filesystem of the specified
     size; when shrinking, resize_lfs must first ``clean'' the segments that will be invalid when
     the filesystem is shrunk.	If this cleaning process results in these segments becoming
     redirtied, this indicates that the given new size is not large enough to contain the exist-
     ing filesystem data, and resize_lfs will return an error.

EXAMPLES
     To resize the file system mounted at /home to 32576 sectors:
	   resize_lfs -s 32576 /home

SEE ALSO
     fsck_lfs(8), lfs_cleanerd(8), newfs_lfs(8)

HISTORY
     The resize_lfs command first appeared in NetBSD 3.0.

BUGS
     resize_lfs should be able to resize an unmounted filesystem as well.
