GROWFS(8) System Manager's Manual GROWFS(8) NAME growfs -- expand an existing UFS file system SYNOPSIS growfs [-Ny] [-s size] special | filesystem DESCRIPTION The growfs utility makes it possible to expand an UFS file system. Be- fore running growfs the partition or slice containing the file system must be extended using gpart(8). If you are using volumes you must en- large them by using gvinum(8). The growfs utility extends the size of the file system on the specified special file. The following options are available: -N "Test mode". Causes the new file system parameters to be printed out without actually enlarging the file system. -s size Determines the size of the file system after enlarging in sec- tors. Size is the number of 512 byte sectors unless suffixed with a b, k, m, g, or t which denotes byte, kilobyte, megabyte, gigabyte and terabyte respectively. This value de- faults to the size of the raw partition specified in special (in other words, growfs will enlarge the file system to the size of the entire partition). -y Causes growfs to assume yes as the answer to all operator questions. EXIT STATUS Exit status is 0 on success, and >= 1 on errors. Errors recoverable by user action are indicated by 2. OS errors, which are usually not re- coverable, are indicated by 3 or greater. EXAMPLES Expand root file system to fill up available space: growfs / Refresh the LUN size, resize the partition to use all available capac- ity, and expand the filesystem accordingly: camcontrol reprobe da0 gpart recover da0 gpart resize -i 1 da0 growfs /dev/da0p1 SEE ALSO growfs(7), camcontrol(8), fsck(8), gpart(8), newfs(8), tunefs(8) HISTORY The growfs utility first appeared in FreeBSD 4.4. The ability to re- size mounted file systems was added in FreeBSD 10.0. AUTHORS Christoph Herrmann <chm@FreeBSD.org> Thomas-Henning von Kamptz <tomsoft@FreeBSD.org> The GROWFS team <growfs@Tomsoft.COM> Edward Tomasz Napierala <trasz@FreeBSD.org> CAVEATS When expanding a file system mounted read-write, any writes to that file system will be temporarily suspended until the expansion is fin- ished. BUGS Normally growfs writes cylinder group summary to disk and reads it again later for doing more updates. This read operation will provide unexpected data when using -N. Therefore, this part cannot really be simulated and will be skipped in test mode. FreeBSD 13.2 October 3, 2023 GROWFS(8)
