+To create a mirror on disks /dev/ad1 and /dev/ad2, create a filesystem, mount,
+unmount and then stop Ic gvinum:
+.Pp
+.Dl "gvinum mirror /dev/ad1 /dev/ad2"
+.Dl "newfs /dev/gvinum/gvinumvolume0"
+.Dl "mount /dev/gvinum/gvinumvolume0 /mnt"
+.Dl "..."
+.Dl "unmount /mnt"
+.Dl "gvinum stop"
+.Pp
+To create a striped mirror on disks /dev/ad1 /dev/ad2 /dev/ad3 and /dev/ad4
+named "data" and create a filesystem:
+.Pp
+.Dl "gvinum mirror -s -n data /dev/ad1 /dev/ad2 /dev/ad3 /dev/ad4"
+.Dl "newfs /dev/gvinum/data"
+.Pp
+To create a raid5 array on disks /dev/ad1 /dev/ad2 and /dev/ad3, with stripesize
+493k you can use the raid5 command:
+.Pp
+.Dl "gvinum raid5 -s 493k /dev/ad1 /dev/ad2 /dev/ad3"
+.Pp
+Then the volume will be created automatically.
+Afterwards, you have to initialize the volume:
+.Pp
+.Dl "gvinum start myraid5vol"
+.Pp
+The initialization will start, and the states will be updated when it's
+finished. The list command will give you information about its progress.
+.Pp
+Imagine that one of the drives fails, and the output of 'printconfig' looks
+something like this:
+.Pp
+.Dl "drive gvinumdrive1 device /dev/ad2"
+.Dl "drive gvinumdrive2 device /dev/???"
+.Dl "drive gvinumdrive0 device /dev/ad1"
+.Dl "volume myraid5vol"
+.Dl "plex name myraid5vol.p0 org raid5 986s vol myraid5vol"
+.Dl "sd name myraid5vol.p0.s2 drive gvinumdrive2 len 32538s driveoffset 265s"
+.Dl "plex myraid5vol.p0 plexoffset 1972s"
+.Dl "sd name myraid5vol.p0.s1 drive gvinumdrive1 len 32538s driveoffset 265s"
+.Dl "plex myraid5vol.p0 plexoffset 986s"
+.Dl "sd name myraid5vol.p0.s0 drive gvinumdrive0 len 32538s driveoffset 265s"
+.Dl "plex myraid5vol.p0 plexoffset 0s"
+.Pp
+Create a new drive with this configuration:
+.Pp
+.Dl "drive gdrive4 device /dev/ad4"
+.Pp
+Then move the stale subdisk to the new drive:
+.Pp
+.Dl "gvinum move gdrive4 myraid5vol.p0.s2"
+.Pp
+Then, initiate the rebuild:
+.Pp
+.Dl "gvinum start myraid5vol.p0"
+.Pp
+The plex will go up form degraded mode after the rebuild is finished. The plex
+can still be used while the rebuild is in progress, although requests might be
+delayed. For a more advanced usage and detailed explanation of gvinum, the
+handbook is recommended.
