我的服务器运行在基于mdadm的4 dIsk软件raid 10上。
伯爵今天发生了一次小停电，closures了服务器，现在只能启动InItrd应急系统（ubuntu 16.04），对四个dIsks中的两个发生“可能过时”的抱怨。 四个dIsks之间的事件有一个微妙的差异。 两个有6531个事件，两个6527个事件。
我试图强有力地重新组合起来：
mdadm --assemble /dev/md0 /dev/sdb /dev/sdc /dev/sdd /dev/sde --force -v 以及无限的力量：
mdadm --assemble /dev/md0 /dev/sdb /dev/sdc /dev/sdd /dev/sde -v
它始终抱怨过时的经验不合时宜。
我怎么能让mdadm忽略事件中的小dIfference？
这里是输出：
