LVMCONFIG(8)                System Manager's Manual               LVMCONFIG(8)

NAME
       lvmconfig - Display and manipulate configuration information

SYNOPSIS
       lvmconfig
           [ option_args ]
           [ position_args ]

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

USAGE
       lvmconfig

           [ -d|--debug ]
           [ -h|--help ]
           [ -q|--quiet ]
           [ -t|--test ]

           [    --profile String ]
           [    --version ]

OPTIONS
       --atversion String
              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.

       --commandprofile String
              The command profile to use for command configuration.  See
              lvm.conf(5) for more information about profiles.

       --config String
              Config settings for the command. These override lvm.conf set-
              tings.  The String arg uses the same format as lvm.conf, or may
              use section/field syntax.  See lvm.conf(5) for more information
              about config.

       -d|--debug ...
              Set debug level. Repeat from 1 to 6 times to increase the detail
              of messages sent to the log file and/or syslog (if configured).

       --driverloaded y|n
              If set to no, the command will not attempt to use device-mapper.
              For testing and debugging.

       -f|--file String
              Write output to the named file.

       -h|--help
              Display help text.

       --ignoreadvanced
              Exclude advanced configuration settings from the output.

       --ignorelocal
              Ignore the local section. The local section should be defined in
              the lvmlocal.conf file, and should contain config settings spe-
              cific to the local host which should not be copied to other
              hosts.

       --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.

       -l|--list
              List config settings with summarizing comment. This is the same
              as using options --typeconfig list --withsummary.

       --lockopt String
              Used to pass options for special cases to lvmlockd.  See lvm-
              lockd(8) for more information.

       --longhelp
              Display long help text.

       --mergedconfig
              When the command is run with --config and/or --commandprofile
              (or using LVM_COMMAND_PROFILE environment variable), --profile,
              or --metadataprofile, merge all the contents of the "config cas-
              cade" before displaying it.  Without merging, only the configu-
              ration at the front of the cascade is displayed.  See
              lvm.conf(5) for more information about config.

       --metadataprofile String
              The metadata profile to use for command configuration.  See
              lvm.conf(5) for more information about profiles.

       --nolocking
              Disable locking.

       --profile String
              An alias for --commandprofile or --metadataprofile, depending on
              the command.

       -q|--quiet ...
              Suppress output and log messages. Overrides --debug and --ver-
              bose.  Repeat once to also suppress any prompts with answer
              'no'.

       --showdeprecated
              Include deprecated configuration settings in the output. These
              settings are deprecated after a certain version. If a concrete
              version is specified with --atversion, deprecated settings are
              automatically included if the specified version is lower than
              the version in which the settings were deprecated. The current
              and diff types include deprecated settings in their output by
              default, all the other types ignore deprecated settings.

       --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 in-
              clude unsupported settings in their output by default, all the
              other types ignore unsupported settings.

       --sinceversion String
              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-
              config new to display all configuration settings introduced
              since given version.

       -t|--test
              Run in test mode. Commands will not update metadata.  This is
              implemented by disabling all metadata writing but nevertheless
              returning success to the calling function. This may lead to un-
              usual error messages in multi-stage operations if a tool relies
              on reading back metadata it believes has changed but hasn't.

       --typeconfig current|default|diff|full|list|missing|new|profilable|pro-
              filable-command|profilable-metadata
              current prints the config settings that would be applied to an
              lvm command (assuming the command does not override them on the
              command line.) This includes: settings that have been modified
              in lvm config files, settings that get their default values from
              config files, and default settings that have been uncommented in
              config files.  default prints all settings with their default
              values.  Changes made in lvm config files are not reflected in
              the output.  Some settings get their default values internally,
              and these settings are printed as comments.  Other settings get
              their default values from config files, and these settings are
              not printed as comments.  diff prints only config settings that
              have been modified from their default values in config files
              (the difference between current and default.)  full prints every
              setting uncommented and set to the current value, i.e. how it
              would be used by an lvm command.  This includes settings modi-
              fied in config files, settings that usually get defaults inter-
              nally, and settings that get defaults from config files.  list
              prints all config names without values.  missing prints settings
              that are missing from the lvm config files. A missing setting
              that usually gets its default from config files is printed un-
              commented and set to the internal default.  Settings that get
              their default internally and are not set in config files are
              printed commented with the internal default.  new prints config
              settings that have been added since the lvm version specified by
              --sinceversion. They are printed with their default values.
              profilable prints settings with their default values that can be
              set from a profile.  profilable-command prints settings with
              their default values that can be set from a command profile.
              profilable-metadata prints settings with their default values
              that can be set from a metadata profile.  Also see lvm.conf(5).

       --unconfigured
              Internal option used for generating config file during build.

       --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, also use --mergedconfig.  The valida-
              tion is done even if lvm.conf config/checks is disabled.

       -v|--verbose ...
              Set verbose level. Repeat from 1 to 4 times to increase the de-
              tail of messages sent to stdout and stderr.

       --version
              Display version information.

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

       --withgeneralpreamble
              Include general config file preamble.

       --withlocalpreamble
              Include local config file preamble.

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

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

       --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.

       -y|--yes
              Do not prompt for confirmation interactively but always assume
              the answer yes. Use with extreme caution.  (For automatic no,
              see -qq.)

VARIABLES
       String
              See the option description for information about the string con-
              tent.

       Size[UNIT]
              Size is an input number that accepts an  optional  unit.   Input
              units are always treated as base two values, regardless of capi-
              talization, e.g. 'k' and 'K' both refer to  1024.   The  default
              input unit is specified by letter, followed by |UNIT.  UNIT rep-
              resents other possible input units:  bBsSkKmMgGtTpPeE.   b|B  is
              bytes,  s|S  is  sectors  of 512 bytes, k|K is kilobytes, m|M is
              megabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes,
              e|E  is  exabytes.  (This should not be confused with the output
              control --units, where capital letters mean multiple of 1000.)

ENVIRONMENT VARIABLES
       See lvm(8) for information about environment  variables  used  by  lvm.
       For example, LVM_VG_NAME can generally be substituted for a required VG
       parameter.
