在重新安装系统后,配置了dedup的储存池中数据无法访问的问题 RRS feed

  • 问题

  • 此前系统是Windows server2016 Datacenter,重新安装了Windows 10 Pro for Workstation之后出现此问题,已经尝试重新安装回Windows server,依旧无法正常访问数据

    重新安装系统之后,所有进行过dedup的文件全部都无法正常读取,另外文件属性显示大小正常,占用空间0字节。

    储存池界面中显示磁盘空间依然正常占用,并且没有任何错误提示

    另外我在原系统中设置了dedup的计划任务,在最后一次计划任务执行之后写入的数据依然可以正常访问。

    请问这种情况数据还可以救回吗,是什么原因导致了这种问题

  • Hi,

    你启用用dedup 的数据文件和是在单独的volume 上对吗?不是在系统盘上?

    一般来说,如果你启用的deduplication 的 volume 都是完整的并没有损坏,而且你把这些盘都mount 到新的机器上,deduplication的数据应该可以被识别。

    Portability: A volume that is under deduplication control is an atomic unit. You can back up the volume and restore it to another server. You can rip it out of one Windows 2012 server and move it to another. Everything that is required to access your data is located on the drive. All of the deduplication settings are maintained on the volume and will be picked up by the deduplication filter when the volume is mounted. The only thing that is not retained on the volume are the schedule settings that are part of the task-scheduler engine. If you move the volume to a server that is not running the Data Deduplication feature, you will only be able to access the files that have not been deduplicated.

    你装完新的系统,新系统上的deduplica 服务用正常启用吗?还有你的存放dedup 文件的盘有损坏或者变动吗?

    你说的无法正常读取,那你去尝试访问的时候报错是什么?
