[править] NAME

    geom -- universal control utility for GEOM classes

[править] SYNOPSIS

    geom class help
    geom class list [-a] [name ...]
    geom class status [-ags] [name ...]
    geom class load [-v]
    geom class unload [-v]

[править] DESCRIPTION

    The geom utility is used to control various GEOM classes.  A class has to
    be aware of geom(8) communication methods, but there are also some stan-
    dard commands which can be used for existing geom(8) unaware classes.
    Here is the list of standard commands:
    help    List all available commands for the given class.
    list    Print detailed information (within the given class) about all
            geoms (if no additional arguments were specified) or the given
            geoms.  This command is only available if the given class exists
            in the kernel.  Additional options include:
            -a  Print information for geoms without providers.
    status  Print general information (within the given class) about all
            geoms (if no additional arguments were specified) or the given
            geoms.  This command is only available if the given class exists
            in the kernel.
            Additional options include:
            -a  When used with -g, print status for geoms without providers.
            -g  Report statuses for geoms instead of providers.
            -s  Produce script-friendly output.
    load    Load the kernel module that implements the given class.  This
            command is only available if the class does not yet exist in the
            kernel and the file geom_<class>.ko can be found in one of the
            directories specified in kern.module_path sysctl.
    unload  Unload the kernel module which implements the given class.  This
            command is only available if the given class is loaded as a ker-
            nel module.
    Class-specific commands are implemented as shared libraries which are
    stored in /lib/geom/ directory and are loaded via dlopen(3) function when
    the class name is known.  When a class-specific shared library exists, a
    direct utility should also be available under the name of gclass.
    Currently available classes which are aware of geom(8):
          o   CACHE
          o   CONCAT
          o   ELI
          o   JOURNAL
          o   LABEL
          o   MIRROR
          o   MOUNTVER
          o   MULTIPATH
          o   NOP
          o   PART
          o   RAID
          o   RAID3
          o   SCHED
          o   SHSEC
          o   STRIPE
          o   VIRSTOR

[править] ENVIRONMENT

    The following environment variables affect the execution of geom:
    GEOM_LIBRARY_PATH  Specifies the path where shared libraries are stored
                       instead of /lib/geom/.  Multiple paths can be speci-
                       fied with a colon-separated list of paths.

[править] EXIT STATUS

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

[править] EXAMPLES

    The following example shows how to set up a stripe on three disks for
    automatic configuration:
          geom stripe label -v -s 65536 data /dev/da0 /dev/da1 /dev/da2
          or:
          gstripe label -v -s 65536 data /dev/da0 /dev/da1 /dev/da2
    Print the list of all providers from the DISK class:
          geom disk list
    Unload a kernel module which implements the MD class:
          geom md unload
