4.3.4. 显​​​​​​​示​​​​​​​卷​​​​​​​组​​​​​​​

您​​​​​​​可​​​​​​​以​​​​​​​使​​​​​​​用​​​​​​​两​​​​​​​个​​​​​​​命​​​​​​​令​​​​​​​来​​​​​​​显​​​​​​​示​​​​​​​ LVM 卷​​​​​​​组​​​​​​​的​​​​​​​属​​​​​​​性​​​​​​​:vgs 和​​​​​​​ vgdisplay。​​​​​​​
The vgs command provides volume group information in a configurable form, displaying one line per volume group. The vgs command provides a great deal of format control, and is useful for scripting. For information on using the vgs command to customize your output, see 第 4.9 节 “为​​​​​​​ LVM 自​​​​​​​定​​​​​​​义​​​​​​​报​​​​​​​告​​​​​​​”.
vgdisplay 命​​​​​​​令​​​​​​​以​​​​​​​固​​​​​​​定​​​​​​​格​​​​​​​式​​​​​​​显​​​​​​​示​​​​​​​卷​​​​​​​组​​​​​​​属​​​​​​​性​​​​​​​(比​​​​​​​如​​​​​​​大​​​​​​​小​​​​​​​、​​​​​​​扩​​​​​​​展​​​​​​​、​​​​​​​物​​​​​​​理​​​​​​​卷​​​​​​​数​​​​​​​量​​​​​​​等​​​​​​​等​​​​​​​)。​​​​​​​下​​​​​​​面​​​​​​​的​​​​​​​例​​​​​​​子​​​​​​​就​​​​​​​是​​​​​​​对​​​​​​​卷​​​​​​​组​​​​​​​ new_vg 执​​​​​​​行​​​​​​​ vgdisplay 命​​​​​​​令​​​​​​​时​​​​​​​的​​​​​​​输​​​​​​​出​​​​​​​结​​​​​​​果​​​​​​​。​​​​​​​如​​​​​​​果​​​​​​​您​​​​​​​没​​​​​​​有​​​​​​​指​​​​​​​定​​​​​​​卷​​​​​​​组​​​​​​​,那​​​​​​​么​​​​​​​就​​​​​​​会​​​​​​​列​​​​​​​出​​​​​​​所​​​​​​​有​​​​​​​现​​​​​​​有​​​​​​​的​​​​​​​卷​​​​​​​组​​​​​​​。​​​​​​​
