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.
