新疆IDC环境部分节点，服务出现僵尸进程且存储路径无法读取，最终导致进程被hang住，无法正常提供服务。
|
|||
|
|
结合系统日志及故障现象，推断为XFS + Software RAID 在Centos 7 Linux version 3.10.0-693.e17.x86_64 在高IO负载时触发system hung on rwsem_down_read_failed bug。具体见关联bug CN-987。

* 需要将两台节点（10.111. 231.124，10.111.154.1 ）系统内核由3.10.0-693.e17.x86_64升级到kernel-3.10.0-1160.el7.x86_64 。
|
|||
|
|
* 将不可用的CK服务加入到集群中，持续观察 。[~qidaijie]
