    DESCRIPTION

    The utility is used for setting up a device which contains a shared secret. The secret is shared between the given providers. To collect the secret, all providers are needed. If one of the components is missing, there is no way to get any useful data from the rest of them. The first argument to indicates an action to be performed:

    label
    Set up a shared secret device from the given components with the specified name Metadata are stored in the last sector of every component.
    stop
    Turn off an existing shared secret device by its name This command does not touch on-disk metadata!
    clear
    Clear metadata on the given providers.
    dump
    Dump metadata stored on the given providers.
    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 shared secret device.
    -h
    Hardcode providers' names in metadata.
    -v
    Be more verbose.

     

    EXIT STATUS

    Exit status is 0 on success, and 1 if the command fails.  

    EXAMPLES

    The following example shows how to create a shared secret device. The secret will be split between a slice on a local disk and a USB Pen drive.
    gshsec label -v secret /dev/ad0s1 /dev/da0
    newfs /dev/shsec/secret
    

    From now on, when the USB Pen drive is inserted, it will be automatically detected and connected, making the secret available via the /dev/shsec/secret device.
