.SH OPTIONS
.HP
.ad l
\fB--atversion\fP \fIString\fP
.br
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 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 settings for which LVM would
issue a warning message when checking the configuration.
.ad b
.HP
.ad l
\fB--commandprofile\fP \fIString\fP
.br
The command profile to use for command configuration.
See \fBlvm.conf\fP(5) for more information about profiles.
.ad b
.HP
.ad l
\fB--config\fP \fIString\fP
.br
Config settings for the command. These override lvm.conf settings.
The String arg uses the same format as lvm.conf,
or may use section/field syntax.
See \fBlvm.conf\fP(5) for more information about config.
.ad b
.HP
.ad l
\fB-d\fP|\fB--debug\fP ...
.br
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).
.ad b
.HP
.ad l
\fB--driverloaded\fP \fBy\fP|\fBn\fP
.br
If set to no, the command will not attempt to use device-mapper.
For testing and debugging.
.ad b
.HP
.ad l
\fB-f\fP|\fB--file\fP \fIString\fP
.br
Write output to the named file.
.ad b
.HP
.ad l
\fB-h\fP|\fB--help\fP
.br
Display help text.
.ad b
.HP
.ad l

.br
Exclude advanced configuration settings from the output.
.ad b
.HP
.ad l
\fB--ignorelocal\fP
.br
Ignore local section.
.ad b
.HP
.ad l
\fB--ignoreunsupported\fP
.br
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 \fBcurrent\fP
and \fBdiff\fP types include unsupported settings in their output by default,
all the other types ignore unsupported settings.
.ad b
.HP
.ad l
\fB-l\fP|\fB--list\fP
.br
List config settings with summarizing comment. This is the same as using
options --typeconfig list --withsummary.
.ad b
.HP
.ad l
\fB--longhelp\fP
.br
Display long help text.
.ad b
.HP
.ad l
\fB--mergedconfig\fP
.br
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 cascade" before displaying it.
Without merging, only the configuration at the front of the
cascade is displayed.
See \fBlvm.conf\fP(5) for more information about config.
.ad b
.HP
.ad l
\fB--metadataprofile\fP \fIString\fP
.br
The metadata profile to use for command configuration.
See \fBlvm.conf\fP(5) for more information about profiles.
.ad b
.HP
.ad l
\fB--profile\fP \fIString\fP
.br
An alias for --commandprofile or --metadataprofile, depending
on the command.
.ad b
.HP
.ad l
\fB-q\fP|\fB--quiet\fP ...
.br
Suppress output and log messages. Overrides --debug and --verbose.
Repeat once to also suppress any prompts with answer no.
.ad b
.HP
.ad l
\fB--showdeprecated\fP
.br
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.
.ad b
.HP
.ad l
\fB--showunsupported\fP
.br
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.
.ad b
.HP
.ad l
\fB--sinceversion\fP \fIString\fP
.br
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).
This option is currently applicable only with --typeconfig new
to display all configuration settings introduced since given version.
.ad b
.HP
.ad l
\fB-t\fP|\fB--test\fP
.br
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 unusual
error messages in multi-stage operations if a tool relies on reading
back metadata it believes has changed but hasn't.

\fB--typeconfig\fP \fBcurrent\fP|\fBdefault\fP|\fBdiff\fP|\fBfull\fP|\fBlist\fP|\fBmissing\fP|\fBnew\fP|\fBprofilable\fP|\fBprofilable-command\fP|\fBprofilable-metadata\fP

\fB--unconfigured\fP
.br
Internal option used for generating config file during build.
.ad b
.HP
.ad l
\fB--validate\fP
.br
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 validation is done even if lvm.conf config/checks is disabled.
.ad b
.HP
.ad l
\fB-v\fP|\fB--verbose\fP ...
.br
Set verbose level. Repeat from 1 to 4 times to increase the detail
of messages sent to stdout and stderr.
.ad b
.HP
.ad l
\fB--version\fP
.br
Display version information.

.HP
.ad l
\fB--withcomments\fP
.br
Display a full comment for each configuration node. For deprecated
settings, also display comments about deprecation.
.ad b

\fB--withspaces\fP
.br
Where appropriate, add more spaces in output for better readability.
.ad b
.HP
.ad l
\fB--withsummary\fP
.br
Display a one line comment for each configuration node.
.ad b
.HP
.ad l
\fB--withversions\fP
.br
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.
.ad b
.HP
.ad l
\fB-y\fP|\fB--yes\fP
.br
Do not prompt for confirmation interactively but always assume the
answer yes. Use with extreme caution.
(For automatic no, see -qq.)
.ad b
.SH VARIABLES
.HP
\fIString\fP
.br
See the option description for information about the string content.
.HP
\fISize\fP[UNIT]
.br
Size is an input number that accepts an optional unit.
Input units are always treated as base two values, regardless of
capitalization, e.g. 'k' and 'K' both refer to 1024.
The default input unit is specified by letter, followed by |UNIT.
UNIT represents other possible input units: \fBbBsSkKmMgGtTpPeE\fP.
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.)
.SH ENVIRONMENT VARIABLES
See \fBlvm\fP(8) for information about environment variables used by lvm.
For example, LVM_VG_NAME can generally be substituted for a required VG parameter.
