SYNOPSIS

lvmconfig [options] [section]

DESCRIPTION

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.

PARAMETERS

--typeconfig _type_

Specify configuration type: current, default, diff, full, list, missing, new, profilable, or profilable-command
--mergedconfig
Merge all configuration sources before display
-l, --list
List all configuration keys
--withcomments
Include explanatory comments in output
--withspaces
Add extra spacing for readability
--validate
Check configuration for errors and report problems
-f, --file _path_
Write output to a file instead of stdout
--config _string_
Override configuration settings from the command line

INSTALL

sudo apt install lvm2
sudo dnf install lvm2
sudo pacman -S lvm2
sudo apk add lvm2
sudo zypper install lvm2
nix profile install nixpkgs#lvm2

CAVEATS

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.
