DESCRIPTION
       lvm dumpconfig produces formatted output with LVM configuration tree.


OPTIONS
       -f, --file filename
              Dump configuration to a file named 'filename'.


       --type {current|default|diff|missing|new|profilable}
              Select  the  type  of configuration to dump. The configuration settings dumped 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 configura‐
              tion setting with a default value is commented out, it means the setting  does  not
              have  any  concrete  default  value  defined. All output can be saved and reused as
              proper lvm.conf(5) file.

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

              default
                 Dump all possible configuration settings with default values assigned.

              diff
                 Dump  all configuration settings for which the values used differ from defaults.
                 The value assigned for each configuration setting is the value  currently  used.
                 This is actually minimal LVM configuration which can be used without a change to
                 current configured behaviour.

              missing
                 Dump 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
                 Dump all new configuration settings introduced in current LVM  version  or  spe‐
                 cific version as defined by --atversion option.

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

              profilable-command
                 Dump all profilable configuration settings with default values assigned that can
                 be used in command profile. This is a subset of settings dumped by --type --pro‐
                 filable.

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


       --atversion version
              Specify an LVM version in x.y.z format where x is the major version, the y  is  the
              minor  version  and  z  is  the  patchlevel  (e.g. 2.2.106).  When configuration is
              dumped, the configuration settings recognized at this LVM version will  be  consid‐
              ered only. This can be used to dump a configuration that certain LVM version under‐
              stands and which does not contain any newer settings for which LVM  would  issue  a
              warning message when checking the configuration.


       --ignoreadvanced
              Ignore advanced configuration settings on dump.


       --ignoreunsupported
              Ignore  unsupported  configuration settings on dump. These settings are either used
              for debugging purposes only or their support is not yet complete and they  are  not
              meant to be used in production.


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


       --commandprofile ProfileName
              Use  ProfileName  to  override  existing configuration.  This configuration is then
              applied for dumpconfig command itself.  See also lvm.conf(5) for  more  info  about
              config cascade.


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


       --metadataprofile ProfileName
              Use ProfileName to override existing configuration.  The configuration  defined  in
              metadata  profile has no effect for dumpconfig command itself, the dumpconfig dumps
              the configuration only.  See also lvm.conf(5) for more info about config cascade.


       --mergedconfig
              When the dumpconfig command is run with the --config  option  and/or  --commandpro‐
              file,  --profile,  --metadataprofile  option,  merge all the contents of the config
              cascade before dumping it.  Without the --mergeconfig option used, only the config‐
              uration  at  the front of the cascade is dumped. See also lvm.conf(5) for more info
              about config cascade.


       --validate
              Validate current configuration used and exit with appropriate return code. The val‐
              idation  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.


       --withcomments
              Also dump comments for each configuration node.


       --withversions
              Also  dump  a comment containing the version of introduction for each configuration
              node.
