设备环境：（物理机、局域网/公网、系统/APP版本号9.29）
BUG现象：（更新9.29后，提示有一块硬盘掉盘，确实某2块硬盘有smart errlog，不过之前是不太影响使用的，后面选修复失败，提示空间损坏要关机插拔，插拔之后有另一个硬盘反应很慢，无论如何开关机都无法识别了，目前更换了数据背板为数据线直连，尝试了论坛提供的恢复方法，系统内可以看到空间正常，但是无法挂载使用。
硬盘信息：

以3块events相同的盘组建后就是这样无法自动或者通过web来挂载空间，这个步骤因为之前不知道cat /proc/mdstat这个命令能看细节，所以创建之后失败也试过关机重试，每次加入最后这个盘都会提示它是个spare 它slot是 -1。
手动启动
xms@HS1581:$ sudo mdadm --assemble --force -v /dev/md1 /dev/sda1 /dev/sdb1 /dev/sdc1

手动加入第四块盘（sde），提示这块盘变为spare，
sudo mdadm --add /dev/md1 /dev/sde1
mdadm: add new device failed for /dev/sde1 as 4: Device or resource busy
然后会看到重建，但是每秒100多k明显不太正常。想问问还有什么方法？

最后试了这个命令，看起来是不是还是有错，这个名录卡住了不动了。
