@ -189,8 +189,8 @@ The following example shows how to set up striped device from four disks
for automatic configuration, create a file system on it, and mount it:
.Bd -literal -offset indent
gstripe label -v -s 4096 data /dev/da0 /dev/da1 /dev/da2 /dev/da3
newfs /dev/data.stripe
mount /dev/data.stripe /mnt
newfs /dev/stripe/data
mount /dev/stripe/data /mnt

umount /mnt
