resize_lfs
—
resize a mounted log-structured filesystem
resize_lfs |
[-v ] [-s

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.
To resize the file system mounted at /home to 32576 sectors:
resize_lfs -s 32576
/home
The resize_lfs
command first appeared in
NetBSD 3.0.

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