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

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