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

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