Check Prerequisites for Creating Solaris Volume Manager Components.
Review the disk space associated with a file system.
# df -hk |
See the df(1M) man page for more information.
Expand a UFS file system on a logical volume.
# growfs -M /mount-point /dev/md/rdsk/volume-name |
Specifies the mount point for the file system to be expanded.
Specifies the name of the volume on which you want to expand.
See the following example and the growfs(1M) man page for more information.
In the following example, a new slice is added to a volume, d10, which contains the mounted file system, /home2. The growfs command specifies the mount point with the -M option to be /home2, which is expanded onto the raw volume /dev/md/rdsk/d10. The file system will span the entire volume when the growfs command is complete. You can use the df -hk command before and after expanding the file system to verify the total disk capacity.

For mirror volumes, always run the growfs command on the top-level volume. Do not run the command on a submirror or master device, even though space is added to the submirror or master device.
