今天磁盤報警，空間不足，找了很久沒查出來。

下面說下我的操作步驟[root@monitor?/]#?du?-sch?/*

161M?????/data

164K?????/dev

一共使用了5.1G磁盤，但是檢查出已經使用15G[root@monitor?/]#?df?-h

Filesystem??????Size??Used?Avail?Use%?Mounted?on

/dev/xvda1???????20G???15G??4.3G??78%?/

tmpfs???????????1.9G??4.0K??1.9G???1%?/dev/shm

很奇怪，問群里的大神說是XEN虛擬機運行java會遇到此bug，重啟java程序就恢復正常[root@monitor?/]#?killall?java

[root@monitor?/]#?ps?-ef?|grep?java

root?????27766?26125??0?11:34?pts/0????00:00:00?grep?java

[root@monitor?/]#?/etc/init.d/elasticsearch?start
