.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is used for setting up stripe on two or more disks.
|
|
The striped device can be configured using two different methods:
|
|
.Dq manual
|
|
or
|
|
.Dq automatic .
|
|
When using the
|
|
.Dq manual
|
|
method, no metadata are stored on the devices, so the striped
|
|
device has to be configured by hand every time it is needed.
|
|
The
|
|
.Dq automatic
|
|
method uses on-disk metadata to detect devices.
|
|
Once devices are labeled, they will be automatically detected and
|
|
configured.
|
|
.Pp
|
|
The first argument to
|
|
.Nm
|
|
indicates an action to be performed:
|
|
.Bl -tag -width ".Cm destroy"
|
|
.It Cm create
|
|
Set up a striped device from the given devices with specified
|
|
.Ar name .
|
|
This is the
|
|
.Dq manual
|
|
method.
|
|
The kernel module
|
|
.Pa geom_stripe.ko
|
|
will be loaded if it is not loaded already.
|
|
.It Cm label
|
|
Set up a striped device from the given devices with the specified
|
|
.Ar name .
|
|
This is the
|
|
.Dq automatic
|
|
method, where metadata are stored in every device's last sector.
|
|
The kernel module
|
|
.Pa geom_stripe.ko
|
|
will be loaded if it is not loaded already.
|
|
.It Cm stop
|
|
Turn off existing striped device by its
|
|
.Ar name .
|
|
This command does not touch on-disk metadata!
|
|
.It Cm destroy
|
|
Same as
|
|
.Cm stop .
|
|
.It Cm clear
|
|
Clear metadata on the given devices.
|
|
.It Cm list
|
|
List all or the given currently configured devices.
|
|
.It Cm load
|
|
Load
|
|
.Pa geom_stripe.ko
|
|
kernel module.
|
|
.It Cm unload
|
|

|
|
.Pa geom_stripe.ko
|
|
kernel module.

.Sh EXAMPLES
|
|
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 65536 data /dev/da0 /dev/da1 /dev/da2 /dev/da3
|
|
newfs /dev/data.stripe
|
|
mount /dev/data.stripe /mnt
|
|
[...]
|
|
umount /mnt
|
|
gstripe stop data
|
|
gstripe unload
