NAME
gconcat -- disk concatenation control utility
SYNOPSIS
gconcat create [-v] name prov prov ...
gconcat destroy [-fv] name ...
gconcat label [-hv] name prov prov ...
gconcat stop [-fv] name ...
gconcat clear [-v] prov ...
gconcat dump prov ...
gconcat list
gconcat status
gconcat load
gconcat unload
DESCRIPTION
The gconcat utility is used for device concatenation configuration. The
concatenation can be configured using two different methods: ``manual''
or ``automatic''. When using the ``manual'' method, no metadata are
stored on the devices, so the concatenated device has to be configured by
hand every time it is needed. The ``automatic'' method uses on-disk
metadata to detect devices. Once devices are labeled, they will be auto-
matically detected and configured.
The first argument to gconcat indicates an action to be performed:
create Concatenate the given devices with specified name. This is the
``manual'' method. The kernel module geom_concat.ko will be
loaded if it is not loaded already.
label Concatenate the given devices with the specified name. This is
the ``automatic'' method, where metadata are stored in every
device's last sector. The kernel module geom_concat.ko will be
loaded if it is not loaded already.
stop Turn off existing concatenate device by its name. This command
does not touch on-disk metadata!
destroy Same as stop.
clear Clear metadata on the given devices.
dump Dump metadata stored on the given devices.
list See geom(8).
status See geom(8).
load See geom(8).
unload See geom(8).
Additional options:
-f Force the removal of the specified concatenated device.
-h Hardcode providers' names in metadata.
Debug level of the CONCAT GEOM class. This can be set to a num-
ber between 0 and 3 inclusive. If set to 0 minimal debug infor-
mation is printed, and if set to 3 the maximum amount of debug
information is printed.
EXIT STATUS
Exit status is 0 on success, and 1 if the command fails.
EXAMPLES
The following example shows how to configure four disks for automatic
concatenation, create a file system on it, and mount it:
gconcat label -v data /dev/da0 /dev/da1 /dev/da2 /dev/da3
newfs /dev/concat/data
mount /dev/concat/data /mnt
[...]
umount /mnt
gconcat stop data
gconcat unload
