红帽全球峰会5.3.13. 备份卷组元数据
在每次修改卷组和逻辑卷配置时都会自动进行元数据备份和归档，除非您在
lvm.conf 文件中禁用该功能。在默认情况下，元数据备份保存在 /etc/lvm/backup 文件中，元数据归档保存在 /etc/lvm/archives 中。您可以手动使用 vgcfgbackup 命令将元数据备份到 /etc/lvm/backup 文件中。
vgcfrestore 命令可为卷组中的所有物理卷从归档中恢复卷组的元数据。
For an example of using the
vgcfgrestore command to recover physical volume metadata, see 第 7.4 节 “修复物理卷元数据”.
