SYNOPSIS

growfs [-Ny] [-s size] special | filesystem

DESCRIPTION

The growfs utility makes it possible to expand an UFS file system. Before running growfs the partition or slice containing the file system must be extended using gpart(8). If you are using volumes you must enlarge 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.
-y "Expert mode". Usually growfs will ask you if you took a backup of your data before and will do some tests whether special is currently mounted or whether there are any active snapshots on the file system specified. This will be suppressed. So use this option with great care!
-s size
  Determines the size of the file system after enlarging in sectors. 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 defaults 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).

EXAMPLES

Expand root file system to fill up available space:

    growfs /

Resize /dev/ada0p1 partition to 2GB and expand the file system:

    gpart resize -i 1 -s 2G ada0

    growfs -s 2G /dev/ada0p1

CAVEATS

When expanding a file system mounted read-write, any writes to that file system will be temporarily suspended until the expansion is finished.

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.
