Rather then combining hardlink creation for the geom(8) binary with shared library build, move libraries to src/lib/geom so they are built and installed normally. Create a common Makefile.classes which is included by both lib/geom/Makefile and sbin/geom/Makefile so the symlink and libraries stay in sync. The relocation of libraries allows libraries to be build for 32-bit compat. This also reduces the number of non-standard builds in the system. This commit is not sufficent to run a 32-bit /sbin/geom on a 64-bit system out of the box as it will look in the wrong place for libraries unless GEOM_LIBRARY_PATH is set appropriatly in the environment.

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is used for setting up a 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 and the stripe will not exist after a reboot (see
|
|
.Sx DESCRIPTION
|
|
above).
|
|
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 an 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 dump
|
|
Dump metadata stored on the given devices.
|
|
.It Cm list
|
|
See
|
|
.Xr geom 8 .
|
|
.It Cm status
|
|
See
|
|

|

|

.El
|
|
.Pp
|
|
Additional options:
|
|
.Bl -tag -width ".Fl s Ar stripesize"
|
|
.It Fl f
|
|
Force the removal of the specified striped device.
|
|
.It Fl h
|
|
Hardcode providers' names in metadata.
|
|
.It Fl s Ar stripesize
|
|
Specifies size of stripe block in bytes.
|
|
The
|
|
.Ar stripesize
|
|
must be a multiple of the largest sector size of all the providers.
|
|
.It Fl v
|
|
Be more verbose.
|
|
.El
|
|
.Sh SYSCTL VARIABLES
|
|
The following
|
|
.Xr sysctl 8
|
|
variables can be used to control the behavior of the
|
|
.Nm STRIPE
|
|
GEOM class.
|
|
The default value is shown next to each variable.
|
|
.Bl -tag -width indent
|
|
.It Va kern.geom.stripe.debug : No 0
|
|
Debug level of the
|
|
.Nm STRIPE
|
|
GEOM class.
|
|
This can be set to a number between 0 and 3 inclusive.
|
|
If set to 0 minimal debug information is printed, and if set to 3 the
|
|
maximum amount of debug information is printed.
|
|
.It Va kern.geom.stripe.fast : No 0
|
|
If set to a non-zero value enable
|
|
.Dq "fast mode"
|
|
instead of the normal
|
|
.Dq "economic mode" .
|
|
Compared to
|
|
.Dq "economic mode" ,
|
|
.Dq "fast mode"
|
|
uses more memory, but it is much faster for smaller stripe sizes.
|
|
If enough memory cannot be allocated,
|
|
.Nm STRIPE
|
|
will fall back to
|
|
.Dq "economic mode" .
|
|
.It Va kern.geom.stripe.maxmem : No 13107200
|
|
Maximum amount of memory that can be consumed by
|
|
.Dq "fast mode"
|
|
(in bytes).
|
|
This
|
|
.Xr sysctl 8
|
|
variable is read-only and can only be set as a tunable in
|
|
.Xr loader.conf 5 .
|
|
.It Va kern.geom.stripe.fast_failed
|
|
A count of how many times
|
|
.Dq "fast mode"
|
|
has failed due to an insufficient amount of memory.
|
|
If this value is large, you should consider increasing the
|
|
.Va kern.geom.stripe.maxmem
|
|
value.
|
|
.El
|
|
.Sh EXIT STATUS
|
|
Exit status is 0 on success, and 1 if the command fails.
|
|
.Sh EXAMPLES
|
|
The following example shows how to set up a striped device from four disks with a
|
|
128KB stripe size for automatic configuration,
|
|
create a file system on it,
|
|
and mount it:
|
|
.Bd -literal -offset indent
|
|
gstripe label -v -s 131072 data /dev/da0 /dev/da1 /dev/da2 /dev/da3
|
|
newfs /dev/stripe/data
|
|
mount /dev/stripe/data /mnt
|
|
[...]
|
|
umount /mnt
|
|
gstripe stop data
|
|
gstripe unload
|
|
.Ed
|
|
.Sh COMPATIBILITY
|
|
The
|
|
.Nm
|
|
interleave is in number of bytes,
|
|
unlike
|
|
.Xr ccdconfig 8
|
|
which use the number of sectors.
|
|
A
|
|
.Xr ccdconfig 8
|
|
.Ar ileave
|
|
of
|
|
.Ql 128
|
|
is 64 KB (128 512B sectors).
|
|
The same stripe interleave would be specified as
|
|
.Ql 65536
|
|
for
|
|
.Nm .
