<p>使用vgconvert命令将卷组“vg1000”从“LVM1”格式转换为“LVM2”格式。在命令行中输入下面的命令</p>
<pre><code class="language-bash">[root@localhost lvm]# vgconvert -M2 vg1000 #转换卷组为&quot;LVM2&quot;格式
Volume group vg1000 successfully converted</code></pre>
<p>使用vgchange命令将卷组设置为活动状态。在命令行中输入下面的命令</p>
<pre><code class="language-bash">[root@localhost lvm]# vgchange -ay vg1000 #设置卷组状态为活动状态
