BUG现象：

存贮空间3一直不能进入休眠，通过监控，发现是/usr/trim/bin/trim进程每5秒钟就会打开一次/vol3,如下：

/usr/trim/bin# fatrace -t | grep '/vol3'
18:30:36.982447 trim(1785722): CO /vol3
18:30:41.996662 trim(1785722): CO /vol3

18:30:57.054996 trim(1785722): C /vol3
18:31:02.068896 trim(1785722): CO /vol3
18:31:07.089021 trim(1785722): O /vol3
