4.3.4. 顯​​​​​​​示​​​​​​​卷​​​​​​​冊​​​​​​​群​​​​​​​組​​​​​​​

您​​​​​​​可​​​​​​​使​​​​​​​用​​​​​​​兩​​​​​​​項​​​​​​​指​​​​​​​令​​​​​​​來​​​​​​​顯​​​​​​​示​​​​​​​ LVM 卷​​​​​​​冊​​​​​​​群​​​​​​​組​​​​​​​的​​​​​​​內​​​​​​​容​​​​​​​：vgs 和​​​​​​​ vgdisplay。​​​​​​​

The vgscan command, which scans all the disks for volume groups and rebuilds the LVM cache file, also displays the volume groups. For information on the vgscan command, see 節 4.3.5, “掃​​​​​​​描​​​​​​​磁​​​​​​​碟​​​​​​​來​​​​​​​找​​​​​​​尋​​​​​​​卷​​​​​​​冊​​​​​​​群​​​​​​​組​​​​​​​以​​​​​​​便​​​​​​​建​​​​​​​立​​​​​​​快​​​​​​​取​​​​​​​檔​​​​​​​案​​​​​​​”.

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 節 4.9, “LVM 的​​​​​​​自​​​​​​​訂​​​​​​​化​​​​​​​回​​​​​​​報​​​​​​​”.

vgdisplay 指​​​​​​​令​​​​​​​會​​​​​​​以​​​​​​​固​​​​​​​定​​​​​​​的​​​​​​​格​​​​​​​式​​​​​​​來​​​​​​​顯​​​​​​​示​​​​​​​卷​​​​​​​冊​​​​​​​群​​​​​​​組​​​​​​​內​​​​​​​容​​​​​​​（例​​​​​​​如​​​​​​​大​​​​​​​小​​​​​​​、​​​​​​​扇​​​​​​​區​​​​​​​、​​​​​​​實​​​​​​​體​​​​​​​卷​​​​​​​冊​​​​​​​數​​​​​​​量​​​​​​​等​​​​​​​等​​​​​​​）。​​​​​​​下​​​​​​​列​​​​​​​範​​​​​​​例​​​​​​​顯​​​​​​​示​​​​​​​了​​​​​​​ vgdisplay 指​​​​​​​令​​​​​​​針​​​​​​​對​​​​​​​於​​​​​​​ new_vg 卷​​​​​​​冊​​​​​​​群​​​​​​​組​​​​​​​的​​​​​​​輸​​​​​​​出​​​​​​​。​​​​​​​若​​​​​​​您​​​​​​​不​​​​​​​指​​​​​​​定​​​​​​​卷​​​​​​​冊​​​​​​​群​​​​​​​組​​​​​​​的​​​​​​​話​​​​​​​，所​​​​​​​有​​​​​​​現​​​​​​​有​​​​​​​的​​​​​​​卷​​​​​​​冊​​​​​​​群​​​​​​​組​​​​​​​就​​​​​​​會​​​​​​​被​​​​​​​顯​​​​​​​示​​​​​​​出​​​​​​​。​​​​​​​
