DESCRIPTION
       lvmconfig produces formatted output from the  LVM  configuration	 tree.
       The  command  was added in release 2.02.119 and has an identical longer
       form lvm dumpconfig.


OPTIONS
       -f, --file Filename
	      Send output to a file named 'filename'.


       -l, --list
	      List configuration settings with summarizing  comment.  This  is
	      the same as using lvmconfig --type list --withsummary.


       --type	 {current|default|diff|full|missing|new|profilable|profilable-
       command|profilable-metadata}
	      Select the type of configuration to display.  The	 configuration
	      settings	displayed have either default values or currently-used
	      values assigned based on	the  type  selected.  If  no  type  is
	      selected, --type current is used by default. Whenever a configu-
	      ration setting with a default value is commented out,  it	 means
	      the  setting  does  not have any concrete default value defined.
	      Output can be saved and used as a proper lvm.conf(5) file.

	      current
		 Display the current lvm.conf configuration  merged  with  any
		 tag  config if used. See also lvm.conf(5) for more info about
		 LVM configuration methods.

	      default
		 Display all possible configuration settings with default val-
		 ues assigned.

	      diff
		 Display  all configuration settings for which the values used
		 differ from defaults.	The value assigned for each configura-
		 tion  setting	is  the value currently used.  Using this type
		 also implies the use of --mergedconfig option.	 This is actu-
		 ally  minimal	LVM  configuration which can be used without a
		 change to current configured behaviour.

	      full
		 Display full configuration tree - a  combination  of  current
		 configuration	tree (--type current) and tree of settings for
		 which default values  are  used  (--type  missing).  This  is
		 exactly  the configuration tree that LVM2 uses during command
		 execution. Using this type also implies the use of  --merged-
		 config	 option. If comments are displayed (see --withcomments
		 and --withsummary options), then for each  setting  found  in
		 existing  configuration  and for which defaults are not used,
		 there's an extra comment line printed to denote this.

	      list
		 Display plain list of configuration settings.

	      missing
		 Display  all  configuration  settings	with  default	values
		 assigned  which  are  missing	in the configuration currently
		 used and for which LVM automatically fallbacks to using these
		 default values.

	      new
		 Display  all new configuration settings introduced in current
		 LVM version or specific version  as  defined  by  --atversion
		 option.

	      profilable
		 Display  all  profilable  configuration settings with default
		 values assigned.  See lvm.conf(5) for more info about profile
		 config method.

	      profilable-command
		 Display  all  profilable  configuration settings with default
		 values assigned that can be used in command profile. This  is
		 a subset of settings displayed by --type profilable.

	      profilable-metadata
		 Display  all  profilable  configuration settings with default
		 values assigned that can be used in metadata profile. This is
		 a subset of settings displayed by --type profilable.


       --atversion Version
	      Specify an LVM version in x.y.z format where x is the major ver-
	      sion, the y is the minor version and z is the  patchlevel	 (e.g.
	      2.2.106).	  When	configuration  is displayed, the configuration
	      settings recognized at this LVM version will be considered only.
	      This  can	 be used to display a configuration that a certain LVM
	      version understands and which does not contain  any  newer  set-
	      tings  for which LVM would issue a warning message when checking
	      the configuration.


       --sinceversion Version
	      Specify an LVM version in x.y.z format where x is the major ver-
	      sion,  the  y is the minor version and z is the patchlevel (e.g.
	      2.2.106).	 This option is currently applicable only with	--type
	      new to display all configuration settings introduced since given
	      version.


       --ignoreadvanced
	      Exclude advanced configuration settings from the output.


       --ignoreunsupported
	      Exclude unsupported  configuration  settings  from  the  output.
	      These  settings  are  either  used for debugging and development
	      purposes only or their support is not yet complete and they  are
	      not  meant  to be used in production. The current and diff types
	      include unsupported settings in their output by default, all the
	      other types ignore unsupported settings.


       --ignorelocal
	      Ignore local section.


       --config ConfigurationString
	      Use  ConfigurationString	to  override  existing	configuration.
	      This configuration is then applied  for  the  lvmconfig  command
	      itself.	See  also  lvm.conf(5) for more info about config cas-
	      cade.


       --commandprofile ProfileName
	      Use ProfileName to override existing configuration.   This  con-
	      figuration  is  then  applied  for the lvmconfig command itself.
	      See also --mergedconfig option and  lvm.conf(5)  for  more  info
	      about config cascade.


       --profile ProfileName
	      The  same as using --commandprofile but the configuration is not
	      applied for the lvmconfig command itself.


       --metadataprofile ProfileName
	      Use ProfileName to override existing configuration.  The config-
	      uration  defined	in metadata profile has no effect for the lvm-
	      config command  itself.  lvmconfig  displays  the	 configuration
	      only.   See  also --mergedconfig option and lvm.conf(5) for more
	      info about config cascade.


       --mergedconfig
	      When the lvmconfig command  is  run  with	 the  --config	option
	      and/or  --commandprofile	(or using LVM_COMMAND_PROFILE environ-
	      ment variable), --profile, --metadataprofile option,  merge  all
	      the  contents of the config cascade before displaying it.	 With-
	      out the --mergeconfig option used, only the configuration at the
	      front of the cascade is displayed. See also lvm.conf(5) for more
	      info about config cascade.


       --showdeprecated
	      Include deprecated configuration settings in the	output.	 These
	      settings	are  always  deprecated since certain version. If con-
	      crete version is specified with --atversion  option,  deprecated
	      settings	are  automatically  included  if  specified version is
	      lower that the version in which the  settings  were  deprecated.
	      The current and diff types include deprecated settings int their
	      output by default, all the other types  ignore  deprecated  set-
	      tings.


       --showunsupported
	      Include  unsupported configuration settings in the output. These
	      settings are either used for debugging or	 development  purposes
	      only or their support is not yet complete and they are not meant
	      to be used in production. The current  and  diff	types  include
	      unsupported  settings  in their output by default, all the other
	      types ignore unsupported settings.


       --validate
	      Validate current configuration used and  exit  with  appropriate
	      return  code.  The validation is done only for the configuration
	      at the front of the config cascade. To validate the whole merged
	      configuration  tree,  use	 also  the --mergedconfig option.  The
	      validation is done even if config/checks lvm.conf(5)  option  is
	      disabled.


       --withsummary
	      Display a one line comment for each configuration node.


       --withcomments
	      Display  a  full comment for each configuration node. For depre-
	      cated settings, also display comments about deprecation in addi-
	      tion.


       --withspaces
	      Where  appropriate,  add	more spaces in output for better read-
	      ability.


       --withversions
	      Also display a comment containing the  version  of  introduction
	      for  each configuration node. If the setting is deprecated, also
	      display the version since which it is deprecated.
