lvmconfig [options] [section]

lvmconfig displays and manipulates Logical Volume Manager (LVM) configuration information. It reads configuration from multiple sources (command line, environment, config files) and can show the effective merged configuration.
The tool supports different configuration views: current shows active settings, default shows built-in defaults, diff shows only non-default values, and full shows everything. It can also validate configuration files for syntax errors and deprecated options.
Configuration sections include global settings, device filters, activation options, and allocation policies for volume groups and logical volumes.

--typeconfig _type_

Specify configuration type: current, default, diff, full, list, missing, new, profilable, or profilable-command

Merge all configuration sources before display

List all configuration keys

Include explanatory comments in output

Add extra spacing for readability

Check configuration for errors and report problems

Write output to a file instead of stdout

Override configuration settings from the command line

Configuration changes made with lvmconfig are not persistent; edit /etc/lvm/lvm.conf directly for permanent changes. The --validate option may not catch all configuration issues, particularly those that depend on runtime conditions.
