+.Sh DESCRIPTION
+The
+.Nm
+utility is used for RAID3 arrays configuration.
+After a device creation, all components are detected and configured
+automatically.
+All operations like failure detection, stale components detection, rebuild
+of stale components etc.\& are done automatically as well.
+The
+.Nm
+utility uses on-disk metadata (the last provider's sector) to store all needed
+information.
+.Pp
+The first argument to
+.Nm
+indicates an action to be performed:
+.Bl -tag -width ".Cm configure"
+.It Cm label
+Create a RAID3 device.
+The last given component will contain parity data, all the rest - regular data.
+Number of components has to be equal to 3, 5, 9, 17, etc\&. (2^n + 1).
+.Pp
+Additional options include:
+.Bl -tag -width ".Fl h"
+.It Fl h
+Hardcode providers' names in metadata.
+.It Fl n
+Turn off autosynchronization of stale components.
+.El
+.It Cm clear
+Clear metadata on the given providers.
+.It Cm configure
+Configure the given device.
+.Pp
+Additional options include:
+.Bl -tag -width ".Fl a"
+.It Fl a
+Turn on autosynchronization of stale components.
+.It Fl d
+Do not hardcode providers' names in metadata.
+.It Fl h
+Hardcode providers' names in metadata.
+.It Fl n
+Turn off autosynchronization of stale components.
+.El
+.It Cm rebuild
+Rebuild the given component forcibly.
+If autosynchronization wasn't turn off for the given device, this command
+hopefully will not be used.
+.It Cm insert
+Add the given component to the existing array, if one of the component was
+removed previously with the
+.Cm remove
+command or one component is missing and will not be connected again.
+.Pp
+Additional options include:
+.Bl -tag -width ".Fl h"
+.It Fl h
+Hardcode providers' names in metadata.
+.El
+.It Cm remove
+Remove the given component from the given array and clear metadata on it.
+.It Cm stop
+Stop the given arrays.
+.Pp
+Additional options include:
+.Bl -tag -width ".Fl f"
+.It Fl f
+Stop the given array even if it is opened.
+.El
+.It Cm list
+List every currently configured devices, if a list of devices is passed as a
+parameter then only those devices will be shown.
+.It Cm load
+Load
+.Pa geom_raid3.ko
+kernel module.
+.It Cm unload
+Unload
+.Pa geom_raid3.ko
+kernel module.
+.El
+.Pp
+Additional options include:
+.Bl -tag -width ".Fl v"

+Be more verbose.

+.Sh EXAMPLES
+Use 3 disks to setup a RAID3 array. Create a file system, mount it, then unmount
+it and stop device:
+.Bd -literal -offset indent
+graid3 label -v data da0 da1 da2
+newfs /dev/raid3/data
+mount /dev/raid3/data /mnt
+[...]
+umount /mnt
+graid3 stop data
+graid3 unload
+.Ed
+.Pp
+.Pp
+Create a RAID3 array, but do not use automatic sunchronization feature.
+Rebuild parity component:
+.Bd -literal -offset indent
+graid3 label -n data da0 da1 da2
+graid3 rebuild data da2
+.Ed
+.Pp
+Replace one data disk with a brand new one:
+.Bd -literal -offset indent
+graid3 remove -n 0 data
+graid3 insert -n 0 data da5
+.Ed
+.Sh DIAGNOSTICS
+Exit status is 0 on success, and 1 if the command fails.
