都是C5 开头的磁盘忙，都是盘阵上的磁盘
那些盘用在DBA上面么？这个时间点是否有什么动作？如果没有，也找下存储的support看一下存储那边是否有性能瓶颈吧~ 上次碰到一个类似的案例，最后是通过重新启动存储解决的。所以建议检查一下存储吧 觉得LS的方法仅是临时解决而已，因为存储短时间有瓶颈的话，如果重启后肯定会释放资源（存储上的CPU\cache）。 vmstat 1 4，磁盘使用率100%，并不能说明存储这边有瓶颈呀？sar这类传统UNIX工具针对做过RAID的磁盘阵列效果不是很好，最好用glance，另外看看交换空间使用率多少了？

我也有遇到和你一样的情况，不知道原因是不是一样，我那边还是存储出的问题。你用的什么存储
