红帽全球峰会6.3.3. 分割卷组
要创建新卷组
yourvg，请使用 vgsplit 命令分割卷组 myvg。
在您可以分割卷组前，必须使逻辑卷失活。如果挂载了文件系统，您必须在失活逻辑卷之前卸载文件系统。
您可以使用
lvchange 命令或者 vgchange 命令使逻辑卷失活。以下命令可以使逻辑卷 mylv 失活并从卷组 myvg 中分割出卷组 yourvg，将物理卷 /dev/sdc1 移动到新的卷组 yourvg 中。
# lvchange -a n /dev/myvg/mylv
# vgsplit myvg yourvg /dev/sdc1
Volume group "yourvg" successfully split from "myvg"
您可以使用
vgs 查看两个卷组的属性。
