红帽全球峰会5.3.11. 分割卷组
要分割卷组的物理卷并创建新的卷组，请使用
vgsplit 命令。
无法在卷组间分割逻辑卷。每个现有的逻辑卷必须完整地存在于物理卷中来构成旧的或者新的卷组。如果需要，您可以使用
pvmove 命令来进行强制分割。
The following example splits off the new volume group
smallvg from the original volume group bigvg.
vgsplit bigvg smallvg /dev/ram15 Volume group "smallvg" successfully split from "bigvg"
# vgsplit bigvg smallvg /dev/ram15
Volume group "smallvg" successfully split from "bigvg"
