RHEL 中逻辑卷的重复数据删除和压缩。
Red Hat Enterprise Linux 8
在 LVM 上部署 VDO 以增加存储容量
摘要
使用逻辑卷管理器(LVM)中的 Virtual Data Optimizer (VDO)功能来管理去重和压缩的逻辑卷。您可以将 VDO 作为 LVM 逻辑卷(LV)一种类型（类似于 LVM 精简配置的卷）来管理。
您可以在 LVM (LVM-VDO)上部署 VDO，来为块访问、文件访问、本地存储和远程存储提供去重的存储。您还可以配置精简配置的 VDO 卷，以避免 VDO 卷的物理空间被 100% 使用。
在将 VDO 卷导入到 LVM 后，您可以使用 LVM 工具管理 VDO 卷。
