5.4.13. 显示逻辑卷

有三个命令可显示 LVM 逻辑卷的属性：lvs、lvdisplay 和 lvscan。

The lvs command provides logical volume information in a configurable form, displaying one line per logical volume. The lvs command provides a great deal of format control, and is useful for scripting. For information on using the lvs command to customize your output, see 第 5.8 节 “为 LVM 自定义报告”.

lvdisplay 命令用混合格式显示物理属性（大小、布局和映射）。

The following command shows the attributes of lvol2 in vg00. If snapshot logical volumes have been created for this original logical volume, this command shows a list of all snapshot logical volumes and their status (active or inactive) as well.

lvdisplay -v /dev/vg00/lvol2

# lvdisplay -v /dev/vg00/lvol2

lvscan 命令扫描系统中所有逻辑卷并将其列出，如下:

lvscan

# lvscan
 ACTIVE                   '/dev/vg0/gfslv' [1.46 GB] inherit
