.SH DESCRIPTION
|
|
lvm dumpconfig produces formatted output with LVM configuration tree.
|
|
|
|
.SH OPTIONS
|
|
.TP
|
|
.BR \-f ", " \-\-file " \fIfilename"
|
|
Dump configuration to a file named 'filename'.
|
|
|
|
.TP
|
|
.IR \fB\-\-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, \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. All output can be saved and reused as proper \fBlvm.conf\fP(5)
|
|
file.
|
|
.RS
|
|
.IP current 3
|
|
Dump 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
|
|
Dump all possible configuration settings with default values assigned.
|
|
.IP diff 3
|
|
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.
|
|
.IP missing 3
|
|
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.
|
|
.IP new 3
|
|
Dump all new configuration settings introduced in current LVM version
|
|
or specific version as defined by \fB\-\-atversion\fP option.
|
|
.IP profilable 3
|
|
Dump all profilable configuration settings with default values assigned.
|
|
See \fBlvm.conf\fP(5) for more info about \fBprofile config\fP method.

.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 dumped, the configuration settings recognized
|
|
at this LVM version will be considered only. This can be used
|
|
to dump a configuration that 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
|
|
.B \-\-ignoreadvanced
|
|
Ignore advanced configuration settings on dump.
|
|
|
|
.TP
|
|
.B \-\-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.
|
|
|
|
.TP
|
|
.B \-\-mergedconfig
|
|
When the dumpconfig command is run with the \fB\-\-config\fP option
|
|
and/or \fB\-\-profile\fP option (common options that are recognized
|
|
by all LVM tools, see also \fBlvm\fP(8)), merge the \fB\-\-config\fP
|
|
and/or \fB\-\-profile\fP config with current configuration used
|
|
(see \fB\-\-type current\fP above). Otherwise, only the configuration
|
|
specified within \fB\-\-config\fP or \fB\-\-profile\fP option is dumped
|
|
(see also \fBlvm.conf\fP(5) for more info about \fBconfig cascade\fP).
|
|
|
|
.TP
|
|
.B \-\-validate
|
|
Validate current configuration used and exit with appropriate
|
|
return code. The validation is done even if \fBconfig/checks\fP
|
|
\fBlvm.conf\fP(5) option is disabled.
|
|
|
|
.TP
|
|
.B \-\-withcomments
|
|
Also dump comments for each configuration node.
|
|
|
|
.TP
|
|
.B \-\-withversions
|
|
Also dump a comment containing the version of introduction for
|
|
each configuration node.
