2块nvme硬盘组的缓存池无法挂载,数据还有没有办法拯救

Featured Replies

2块nvme硬盘组的缓存池,存放的appdata、domain、system文件夹,远程桌面win10虚拟机使用中突然应用卡住,尝试虚拟机关机重启没有反应,在网页中把虚拟机强制停止后尝试重新启动时报错文件只读,尝试重启unraid后这2块硬盘就报错“无法挂载:不支持的文件系统或无文件系统”。请问这种情况下还有没有办法恢复出这个btrfs格式的硬盘上的虚拟机镜像文件来?最关键的工作开发的程序源代码存放在里面的虚拟机里,本以为有raid1应该不至于硬盘同时坏也没有勤快备份,之前的备份只有4个月前升级时替换下来的2块小容量硬盘里的旧数据了

两块盘同时坏了吗?

这里有恢复的指导

没有ECC内存用Btrfs这类cow的文件系统容易出问题,我那台之前缓存池用了btrfs,基本4-5个月就会变成只读一次,现在改成xfs在用了,本身也没用到snapshot,所以影响也不大

感谢,我研究下看看能不能救回来

有 ECC 的话也是换 ZFS 比较好,半月前啥都没整,RAID 0 Balance 到了八十九文件系统就自己炸只读了...... 修了半天没修好,恢复数据还丢了 300GiB.
