SYNOPSIS

ggatel create [-v] [-o ro | wo | rw] [-q queue_size] [-s sectorsize] [-t timeout] [-u unit] path ggatel attach [-v] [-o ro | wo | rw] -u unit path ggatel destroy [-f] -u unit ggatel list [-v] [-u unit]

DESCRIPTION

The ggatel utility is a local GEOM Gate class consumer. It can be used as a replacement for md(4) devices or as a "GEOMificator" for non GEOM-aware devices, but it was mainly created as an example on how to use and how to communicate with the GEOM Gate kernel module.

Available commands:

create Create a ggate provider related to the given regular file or device.
attach Attach a worker process to an existing ggate provider.
destroy Destroy the given ggate provider.
list List ggate providers.

Available options:

-f Forcibly destroy ggate provider (cancels all pending requests).
-o ro | wo | rw Specify permission to use when opening the file or device: read-only (ro), write-only (wo), or read-write (rw). Default is rw.
-q queue_size Number of pending I/O requests that can be queued before they will start to be canceled. Default is 1024.
-s sectorsize Sector size for ggate provider. If not specified, it is taken from device, or set to 512 bytes for files.
-t timeout Number of seconds to wait before an I/O request will be canceled. 0 means no timeout. Default is 30.
-u unit Unit number to use.
-v Do not fork, run in foreground and print debug informations on standard output.
path Path to a regular file or device.

EXIT STATUS

Exit status is 0 on success, or 1 if the command fails. To get details about the failure, ggatel should be called with the -v option.

EXAMPLES

"GEOMify" the "fd0" device and use gbde(8) to encrypt data on a floppy.
ggatel create -u 5 /dev/fd0
gbde init /dev/ggate5
gbde attach ggate5
newfs /dev/ggate5.bde
mount /dev/ggate5.bde /secret
cp /private/foo /secret/
umount /secret
gbde detach ggate5
ggatel destroy -u 5
