32 .Nd "universal control utility for GEOM classes"
58 utility is used to control various GEOM classes.
59 A class has to be aware of
61 communication methods, but there are also some standard commands
62 which can be used for existing
65 Here is the list of standard commands:
66 .Bl -tag -width ".Cm status"
68 List all available commands for the given class.
70 Print detailed information (within the given class) about all geoms
71 (if no additional arguments were specified) or the given geoms.
72 This command is only available if the given class exists in the kernel.
73 Additional options include:
74 .Bl -tag -width ".Fl a"
76 Print information for geoms without providers.
79 Print general information (within the given class) about all geoms
80 (if no additional arguments were specified) or the given geoms.
81 This command is only available if the given class exists in the kernel.
83 Additional options include:
84 .Bl -tag -width ".Fl s"
86 When used with -g, print status for geoms without providers.
88 Report statuses for geoms instead of providers.
90 Produce script-friendly output.
93 Load the kernel module that implements the given class.
94 This command is only available if the class does not yet exist in the kernel and
96 .Pa geom_ Ns Ao Ar class Ac Ns Pa .ko
97 can be found in one of the directories specified in
101 Unload the kernel module which implements the given class.
102 This command is only available if the given class is loaded as a
106 Class-specific commands are implemented as shared libraries which
109 directory and are loaded via
111 function when the class name is known.
112 When a class-specific shared library exists, a direct utility should also be
113 available under the name of
116 Currently available classes which are aware of
119 .Bl -bullet -offset indent -compact
154 The following environment variables affect the execution of
156 .Bl -tag -width ".Ev GEOM_LIBRARY_PATH"
157 .It Ev GEOM_LIBRARY_PATH
158 Specifies the path where shared libraries are stored instead of
160 Multiple paths can be specified with a colon-separated list of paths.
163 Exit status is 0 on success, and 1 if the command fails.
165 The following example shows how to set up a stripe on three disks for automatic
167 .Bd -literal -offset indent
168 geom stripe label -v -s 65536 data /dev/da0 /dev/da1 /dev/da2
170 gstripe label -v -s 65536 data /dev/da0 /dev/da1 /dev/da2
173 Print the list of all providers from the DISK class:
174 .Bd -literal -offset indent
178 Unload a kernel module which implements the MD class:
179 .Bd -literal -offset indent
