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 cur-
     rent 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 existing 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

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