事件描述：我们的虚拟化是防火墙，虚拟化交换机，三台服务器，一台raid50， 12块硬盘存储，开始是发现是几乎所有服务器无法登陆，中心管理机器也不能登录能登录的服务器命令基础命令都不能用，数据库也没了，然后就怀疑是黑客黑了我们，但是又不像，最后发现服务器不能写，就想着是虚拟化系统软件或存储存储服务器坏了，经过和戴尔售后确认不是硬件问题，接着就排查虚拟化，找到是服务器建的太多，镜像备份太大存储写爆了，处理方法是你弄虚拟化的话，一个专门备份用的机器要单独挂个硬盘，还有那个虚拟化管理机器最好也单独弄个硬盘，不像我们中心管理机也都用的存储，存储坏了，中心控制机也登不了 ；最后处理，删除空闲机器，但是从磁盘删除后，占用存储并没有释放，下面就是vmkfstools释放空闲存储命令
ssh -px root@存储
列出设备信息esxcli storage core path list
监测是否支持vmkfstools
esxcli storage core device vaai status get -d naa.6019cbe163c74fb1a017256e2e9bc457
释放空闲存储大小
# cd /vmfs/volumes/volume_name
# vmkfstools -y percentage_of_deleted_blocks_to_reclaim
vmkfstools -y 60释放空闲存储空间的百分之60大小
/dev # esxcli storage core path list
