growfs
— grow size
of an existing ffs file system
growfs |
[-Nqy ] [-s
size] special |
The growfs
utility extends the
newfs(8) program. Before starting
growfs
, the partition must be set to a larger size
using disklabel(8). The
growfs
utility extends the size of the file system
on the specified special file.
Currently growfs
can only enlarge
unmounted file systems. Do not try enlarging a mounted file system - your
system may panic and you will not be able to use the file system any longer.
Most of the newfs(8) options cannot be
changed by growfs
. In fact, you can only increase
the size of the file system. Use
tunefs(8) for other changes.
The following options are available:
-N
-q
growfs
will not print extraneous information like superblock backups.-s
sizegrowfs
will enlarge the file system to the size of
the entire partition).-y
growfs
will ask you if you
have taken a backup of your data and will test whether
special is currently mounted. The
-y
flag suppresses this, so use this option with
great care!COLUMNS
growfs
defaults to the
terminal width, or 80 columns if the output is not a terminal.disklabel(8), dumpfs(8), fdisk(8), fsck(8), newfs(8), tunefs(8)
The growfs
utility first appeared in
FreeBSD 4.4 and has been available since
OpenBSD 3.4.

Filesystems must be checked with fsck(8) after enlarging.
