GEOM(8) BSD System Manager's Manual GEOM(8) NAME geom -- universal control utility for GEOM classes SYNOPSIS geom class help geom class list [name ...] geom class status [-s] [name ...] geom class load [-v] geom class unload [-v] DESCRIPTION The geom utility is used to control various GEOM classes. A class has to be aware of geom(8) comunication 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 ge- oms (if no additional arguments were specified) or the given ge- oms. This command is only available if the given class exists in the kernel. status Print general information (within the given class) about all ge- oms (if no additional arguments were specified) or the given ge- oms. This command is only available if the given class exists in the kernel. Additional options include: -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 specifed 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 CONCAT o ELI o LABEL o MIRROR o NOP o RAID3 o SHSEC o STRIPE o VIRSTOR 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. EXIT STATUS Exit status is 0 on success, and 1 if the command fails. EXAMPLES The following example shows how to set up a stripe on three disks for au- tomatic 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 SEE ALSO geom(4), gconcat(8), geli(8), glabel(8), gmirror(8), gnop(8), graid3(8), gshsec(8), gstripe(8), gvirstor(8) HISTORY The geom utility appeared in FreeBSD 5.3.
