安装环境：物理机，G4560 CPU。
系统：0.9.2
存储空间基本信息：7块HDD组RAID6，已使用约80%容积。
当前故障：RAID6阵列failed，终端中提示not enough operational devices ( 3/7 FAILED ) 提示坏三块盘。但是跑SMART检测所有盘没有物理损坏。
问题发生前后的操作：没有任何读写操作，（下面的描述还原子系统日志）早上8点所有磁盘进入休眠状态；当晚十一点突然有三条“推出磁盘”，推出了sd[aef]，接着就是一条存储空间1损坏的消息；接着又有三条日志显示“插入磁盘”插入了sd[aij]；
经过我自己用sudo mdadm --examine得到：（详见下方代码块）
有三块盘update time落后了十多个小时，
为Sat May 17 08:23:45 2025，且这三块盘的ARRAYSTATE是AAAAAAA，Events=60
剩余4块盘（updatetime Sat May 17 23:10:01 2025）是AA.AA.. , Events=64
因此我推测应该是元数据不同步导致的掉盘，这期间没有读写数据，update可能时系统周期性update 。
