微软在 Win10 1703中将ReFS从1.2更新到3.2(Windows 10 Insider Preview 15002 开始加入该特性),这本来算是好事,现在1703 版的Win 10可将任意本地硬盘格式化为ReFS格式,不再要求是存储池内奇偶校验或者镜像分区,而且根据微软的介绍,ReFS对虚拟机文件系统有优化,创建固定空间的VHDs仅需几秒钟
Accelerated VM operations - ReFS introduces new functionality specifically targeted to improve the performance of virtualized workloads:
- Block cloning - Block cloning accelerates copy operations, enabling quick, low-impact VM checkpoint merge operations.
- Sparse VDL - Sparse VDL allows ReFS to zero files rapidly, reducing the time needed to create fixed VHDs from 10s of minutes to mere seconds.
但微软作死的会自动升级ReFS 3.1 到ReFS3.2,微软论坛有人反馈 ,Win server 2016 创建的ReFS 3.1插到Win10 15002上时被自动升级到ReFS 3.2,然后插回2016就无法识别了,而且没有ReFS降级方法
Connecting ReFS v2(3.1) volume to Windows 10 build 15002 will no longer be readable on Windows Server 2016
微软论坛一直没有官方回复,但有4个用户表示遇到同样问题
ReFS 3.2- Version of formatted by Windows 10 v1703.
- Version that can be formatted with Windows 10 Insider Preview 15002 or later.
