14 lvmconfig, lvm config, lvm dumpconfig (for compatibility reasons, to be
15 phased out) produce formatted output from the LVM configuration tree.
16 The sources of the configuration data include lvm.conf(5) and command
17 line settings from --config.

59
61 --atversion String
62 Specify an LVM version in x.y.z format where x is the major ver‐
63 sion, the y is the minor version and z is the patchlevel (e.g.
64 2.2.106). When configuration is displayed, the configuration
65 settings recognized at this LVM version will be considered only.
66 This can be used to display a configuration that a certain LVM
67 version understands and which does not contain any newer set‐
68 tings for which LVM would issue a warning message when checking
69 the configuration.
70 --commandprofile String
72 The command profile to use for command configuration. See
73 lvm.conf(5) for more information about profiles.
74 --config String
76 Config settings for the command. These override lvm.conf set‐
77 tings. The String arg uses the same format as lvm.conf, or may
78 use section/field syntax. See lvm.conf(5) for more information
79 about config.
80 -d|--debug ...
82 Set debug level. Repeat from 1 to 6 times to increase the detail
83 of messages sent to the log file and/or syslog (if configured).
84 --driverloaded y|n
86 If set to no, the command will not attempt to use device-mapper.
87 For testing and debugging.
88 -f|--file String
90 Write output to the named file.
91 -h|--help
93 Display help text.
94 --ignoreadvanced
96 Exclude advanced configuration settings from the output.
97 --ignorelocal
99 Ignore the local section. The local section should be defined in
100 the lvmlocal.conf file, and should contain config settings spe‐
101 cific to the local host which should not be copied to other
102 hosts.
103 --ignoreunsupported
105 Exclude unsupported configuration settings from the output.
106 These settings are either used for debugging and development
107 purposes only or their support is not yet complete and they are
108 not meant to be used in production. The current and diff types
109 include unsupported settings in their output by default, all the
110 other types ignore unsupported settings.
111 -l|--list
113 List config settings with summarizing comment. This is the same
114 as using options --typeconfig list --withsummary.
115 --lockopt String
117 Used to pass options for special cases to lvmlockd. See lvm‐
118 lockd(8) for more information.
119 --longhelp
121 Display long help text.
122 --mergedconfig
124 When the command is run with --config and/or --commandprofile
125 (or using LVM_COMMAND_PROFILE environment variable), --profile,
126 or --metadataprofile, merge all the contents of the "config cas‐
127 cade" before displaying it. Without merging, only the configu‐
128 ration at the front of the cascade is displayed. See
129 lvm.conf(5) for more information about config.
130 --metadataprofile String
132 The metadata profile to use for command configuration. See
133 lvm.conf(5) for more information about profiles.
134 --profile String
136 An alias for --commandprofile or --metadataprofile, depending on
137 the command.
138 -q|--quiet ...
140 Suppress output and log messages. Overrides --debug and --ver‐
141 bose. Repeat once to also suppress any prompts with answer
142 'no'.
143 --showdeprecated
145 Include deprecated configuration settings in the output. These
146 settings are deprecated after a certain version. If a concrete
147 version is specified with --atversion, deprecated settings are
148 automatically included if the specified version is lower than
149 the version in which the settings were deprecated. The current
150 and diff types include deprecated settings in their output by
151 default, all the other types ignore deprecated settings.
152 --showunsupported
154 Include unsupported configuration settings in the output. These
155 settings are either used for debugging or development purposes
156 only, or their support is not yet complete and they are not
157 meant to be used in production. The current and diff types
158 include unsupported settings in their output by default, all the
159 other types ignore unsupported settings.
160 --sinceversion String
162 Specify an LVM version in x.y.z format where x is the major ver‐
163 sion, the y is the minor version and z is the patchlevel (e.g.
164 2.2.106). This option is currently applicable only with --type‐
165 config new to display all configuration settings introduced
166 since given version.
167 -t|--test
169 Run in test mode. Commands will not update metadata. This is
170 implemented by disabling all metadata writing but nevertheless
171 returning success to the calling function. This may lead to
172 unusual error messages in multi-stage operations if a tool
173 relies on reading back metadata it believes has changed but
174 hasn't.
175 --typeconfig current|default|diff|full|list|missing|new|profilable|pro‐
177 filable-command|profilable-metadata
178 current prints the config settings that would be applied to an
179 lvm command (assuming the command does not override them on the
180 command line.) This includes: settings that have been modified
181 in lvm config files, settings that get their default values from
182 config files, and default settings that have been uncommented in
183 config files. default prints all settings with their default
184 values. Changes made in lvm config files are not reflected in
185 the output. Some settings get their default values internally,
186 and these settings are printed as comments. Other settings get
187 their default values from config files, and these settings are
188 not printed as comments. diff prints only config settings that
189 have been modified from their default values in config files
190 (the difference between current and default.) full prints every
191 setting uncommented and set to the current value, i.e. how it
192 would be used by an lvm command. This includes settings modi‐
193 fied in config files, settings that usually get defaults inter‐
194 nally, and settings that get defaults from config files. list
195 prints all config names without values. missing prints settings
196 that are missing from the lvm config files. A missing setting
197 that usually gets its default from config files is printed
198 uncommented and set to the internal default. Settings that get
199 their default internally and are not set in config files are
200 printed commented with the internal default. new prints config
201 settings that have been added since the lvm version specified by
202 --sinceversion. They are printed with their default values.
203 profilable prints settings with their default values that can be
204 set from a profile. profilable-command prints settings with
205 their default values that can be set from a command profile.
206 profilable-metadata prints settings with their default values
207 that can be set from a metadata profile. Also see lvm.conf(5).
208 --unconfigured
210 Internal option used for generating config file during build.
211 --validate
213 Validate current configuration used and exit with appropriate
214 return code. The validation is done only for the configuration
215 at the front of the "config cascade". To validate the whole
216 merged configuration tree, also use --mergedconfig. The valida‐
217 tion is done even if lvm.conf config/checks is disabled.
218 -v|--verbose ...
220 Set verbose level. Repeat from 1 to 4 times to increase the
221 detail of messages sent to stdout and stderr.
222 --version
224 Display version information.
225 --withcomments
227 Display a full comment for each configuration node. For depre‐
228 cated settings, also display comments about deprecation.
229 --withgeneralpreamble
231 Include general config file preamble.
232 --withlocalpreamble
234 Include local config file preamble.
235 --withspaces
237 Where appropriate, add more spaces in output for better read‐
238 ability.
239 --withsummary
241 Display a one line comment for each configuration node.
242 --withversions
244 Also display a comment containing the version of introduction
245 for each configuration node. If the setting is deprecated, also
246 display the version since which it is deprecated.
247 -y|--yes
249 Do not prompt for confirmation interactively but always assume
250 the answer yes. Use with extreme caution. (For automatic no,
251 see -qq.)
252
254 String
255 See the option description for information about the string con‐
256 tent.
257 Size[UNIT]
259 Size is an input number that accepts an optional unit. Input
260 units are always treated as base two values, regardless of capi‐
261 talization, e.g. 'k' and 'K' both refer to 1024. The default
262 input unit is specified by letter, followed by |UNIT. UNIT rep‐
263 resents other possible input units: bBsSkKmMgGtTpPeE. b|B is
264 bytes, s|S is sectors of 512 bytes, k|K is kilobytes, m|M is
265 megabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes,
266 e|E is exabytes. (This should not be confused with the output
267 control --units, where capital letters mean multiple of 1000.)
268
270 See lvm(8) for information about environment variables used by lvm.
271 For example, LVM_VG_NAME can generally be substituted for a required VG
272 parameter.
