系统:ubuntu 14.04
早晨来了发现一个根目录磁盘使用率100%的报警,但是登陆进去查看空间发现实际使用量大概才12G远远达不到100%

用lsof查看了下,发现大量的deteled进程未释放
# lsof | grep deleted

既然找到了原因就OK了,那就直接开始处理
# ps -ef | grep java # 查看具体的java进程,为待会儿重启做准备
# lsof | grep deleted | grep -v grep | awk ‘{print $2}’ | xargs kill -9
处理时间比较长,需要等待一段时间,强烈建议在没人使用的时候进行操作,处理的效果非常好,基本上清理干净了

最后:
也是最最最最最最最最最重要的一点:把刚才干掉的服务重新启动起来

I’m not sure exactly why but this web site is loading incredibly slow for me.
Is anyone else having this issue or is it a problem
on my end? I’ll check back later and see if the problem still exists.
