说明
lvmdump collects diagnostic information about the LVM2 (Logical Volume Manager) subsystem for troubleshooting purposes. By default, it creates a compressed tar archive in the home directory containing system information, LVM configuration, and status data. The dump includes output from commands like pvs, vgs, lvs, configuration files, dmsetup info, and relevant system information. When used with the -m flag, it also captures the raw metadata from all volume groups. This tool is primarily used when reporting LVM issues to developers or support teams, providing all the context needed to diagnose problems.
