Just for convenience to display all new configuration settings
introduced since given version (before, there was only --atversion
to display settings introduced in concrete version).
For example:
$ lvmconfig --type new --sinceversion 2.2.120
allocation {
# cache_mode="writethrough"
# cache_settings {
# }
}
global {
use_lvmlockd=0
# lvmlockd_lock_retries=3
# sanlock_lv_extend=256
use_lvmpolld=1
}
activation {
}
# report {
# compact_output_cols=""
# time_format="%Y-%m-%d %T %z"
# }
local {
# host_id=0

.SH 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
|
|
\fBlvm dumpconfig\fP.
|
|
|
|
.SH OPTIONS
|
|
.TP
|
|
.BR \-f ", " \-\-file " \fIfilename"
|
|
Send output to a file named 'filename'.
|
|
|
|
.TP
|
|
.BR \-l ", " \-\-list
|
|
List configuration settings with summarizing comment. This is the same as using
|
|
\fBlvmconfig --type list --withsummary\fP.
|
|
|
|
.TP
|
|
.IR \fB\-\-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, \fB\-\-type current\fP is used
|
|
by default. Whenever a configuration 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 \fBlvm.conf\fP(5)
|
|
file.
|
|
.RS
|
|
.IP current 3
|
|
Display the current \fBlvm.conf\fP configuration merged with any \fBtag
|
|
config\fP if used. See also \fBlvm.conf\fP(5) for more info about LVM
|
|
configuration methods.
|
|
.IP default 3
|
|
Display all possible configuration settings with default values assigned.
|
|
.IP diff 3
|
|
Display 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.
|
|
.IP full 3
|
|
Display full configuration tree - a combination of current configuration tree
|
|
(\fB\-\-type current\fP) and tree of settings for which default values are
|
|
used (\fB\-\-type missing\fP). This is exactly the configuration tree that
|
|
LVM2 uses during command execution. Using this type also implies
|
|
the use of \fB\-\-mergedconfig\fP option. If comments are displayed
|
|
(see \fB\-\-withcomments\fP and \fB\-\-withsummary\fP 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.
|
|
.IP list 3
|
|
Display plain list of configuration settings.
|
|
.IP missing 3
|
|
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.
|
|
.IP new 3
|
|
Display all new configuration settings introduced in current LVM version
|
|
or specific version as defined by \fB\-\-atversion\fP option.
|
|
.IP profilable 3
|
|
Display all profilable configuration settings with default values assigned.
|
|
See \fBlvm.conf\fP(5) for more info about \fBprofile config\fP method.
|
|
.IP profilable-command 3
|
|
Display all profilable configuration settings with default values assigned
|
|
that can be used in command profile. This is a subset of settings displayed
|
|
by \fB\-\-type \-\-profilable\fP.
|
|
.IP profilable-metadata 3
|
|
Display all profilable configuration settings with default values assigned
|
|
that can be used in metadata profile. This is a subset of settings displayed
|
|
by \fB\-\-type \-\-profilable\fP.
|
|
.RE

|
.TP
|
|
.BI \-\-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 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.
|
|
|
|
.TP
|
|
.BI \-\-sinceversion " 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).
|
|
This option is currently applicable only with \fB\-\-type new\fP
|
|
to display all configuration settings introduced since given version.
|
|
|
|
.TP
|
|
.B \-\-ignoreadvanced
|
|
Exclude advanced configuration settings from the output.
|
|
|
|
.TP
|
|
.B \-\-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 \fBcurrent\fP
|
|
and \fBdiff\fP types include unsupported settings in their output by default,
|
|
all the other types ignore unsupported settings.
|
|
|
|
.TP
|
|
.B \-\-ignorelocal
|
|
Ignore local section.
|
|
|
|
.TP
|
|
.BI \-\-config " ConfigurationString"
|
|
Use \fBConfigurationString\fP to override existing configuration.
|
|
This configuration is then applied for the lvmconfig command itself.
|
|
See also \fBlvm.conf\fP(5) for more info about \fBconfig cascade\fP.
|
|
|
|
.TP
|
|
.BI \-\-commandprofile " ProfileName"
|
|
Use \fBProfileName\fP to override existing configuration.
|
|
This configuration is then applied for the lvmconfig command itself.
|
|
See also \fB\-\-mergedconfig\fP option and \fBlvm.conf\fP(5) for
|
|
more info about \fBconfig cascade\fP.
|
|
|
|
.TP
|
|
.BI \-\-profile " ProfileName"
|
|
The same as using \fB\-\-commandprofile\fP but the configuration is not
|
|
applied for the lvmconfig command itself.
|
|
|
|
.TP
|
|
.BI \-\-metadataprofile " ProfileName"
|
|
Use \fBProfileName\fP to override existing configuration.
|
|
The configuration defined in metadata profile has no effect for
|
|
the lvmconfig command itself. lvmconfig displays the configuration only.
|
|
See also \fB\-\-mergedconfig\fP option and \fBlvm.conf\fP(5) for more
|
|
info about \fBconfig cascade\fP.
|
|
|
|
.TP
|
|
.B \-\-mergedconfig
|
|
When the lvmconfig command is run with the \fB\-\-config\fP option
|
|
and/or \fB\-\-commandprofile\fP (or using \fBLVM_COMMAND_PROFILE\fP
|
|
environment variable), \fB\-\-profile\fP, \fB\-\-metadataprofile\fP
|
|
option, merge all the contents of the \fBconfig cascade\fP before displaying it.
|
|
Without the \fB\-\-mergeconfig\fP option used, only the configuration at
|
|
the front of the cascade is displayed. See also \fBlvm.conf\fP(5) for more
|
|
info about \fBconfig cascade\fP.
|
|
|
|
.TP
|
|
.B \-\-showdeprecated
|
|
Include deprecated configuration settings in the output. These settings
|
|
are always deprecated since certain version. If concrete version is specified
|
|
with \fB--atversion\fP option, deprecated settings are automatically included
|
|
if specified version is lower that the version in which the settings were
|
|
deprecated. The \fBcurrent\fP and \fBdiff\fP types include deprecated settings
|
|
int their output by default, all the other types ignore deprecated settings.
|
|
|
|
.TP
|
|
.B \-\-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
|
|
\fBcurrent\fP and \fBdiff\fP types include unsupported settings in their
|
|
output by default, all the other types ignore unsupported settings.
|
|
|
|
.TP
|
|
.B \-\-validate
|
|
Validate current configuration used and exit with appropriate
|
|
return code. The validation is done only for the configuration
|
|
at the front of the \fBconfig cascade\fP. To validate the whole
|
|
merged configuration tree, use also the \fB\-\-mergedconfig\fP option.
|
|
The validation is done even if \fBconfig/checks\fP \fBlvm.conf\fP(5)
|
|
option is disabled.
|
|
|
|
.TP
|
|
.B \-\-withsummary
|
|
Display a one line comment for each configuration node.
|
|
|
|
.TP
|
|
.B \-\-withcomments
|
|
Display a full comment for each configuration node. For deprecated
|
|
settings, also display comments about deprecation in addition.
|
|
|
|
.TP
|
|
.B \-\-withspaces
|
|
Where appropriate, add more spaces in output for better readability.
|
|
|
|
.TP
|
|
.B \-\-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.
