RESIZE_LFS(8)               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
     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

HISTORY
     The resize_lfs command first appeared in NetBSD 3.0.

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