RESIZE_LFS(8) FreeBSD 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
