出现了两次。
第一次因为使用了一个存在异常的SSD当做加速盘，最后文件系统出错，最后不得已重建raid5.
刚刚出现了第二次，这次没有使用ssd加速，硬盘smart正常，但是无法挂载阵列, check也发生异常。
其实还遇到了很多问题，例如ups，必须要手动修改 sudo vi /etc/nut/ups.conf配置。只保留driver和port，然后页面才能成功配置，具体日志我已经在10天前通过反馈表单功能已经反馈了，但是没有人回复，最后解决方案是AI告诉我的。
例如还有这个问题 智能识别无法使用 - BUG反馈 飞牛私有云论坛 fnOS
那些都是小问题，主要是这个文件系统很容易损坏，这才是大问题, 我就记得出问题之前想关闭换硬盘，最后点了关机过了20分钟还没有关成功，页面和ssh又进去不，连接hdmi又不显示，最后不得已强制关机了。不清楚是不是这个操作导致的问题。
不过之前使用truenas时也强制关过几次，有问题的话通过重新校验修复也都恢复了，fnos这个btrfs使用不到一个月，raid5文件系统挂了两次。
