Plum's Blog - Ubuntu 14.04 下 TRIM 的启用 的评论 今天,我发现我被骗了。TRIM Enabled By Default For SSDs On Ubuntu 14.04 Trusty Tahr当时看到这个新闻还有点激动,因为不需要自己改了,于是... 2016-03-09T12:15:15+08:00 Typecho https://plumz.me/feed/atom/archives/1428 <![CDATA[恒河沙数1]]> https://plumz.me/archives/1428/#comment-120339 2016-03-09T12:15:15+08:00 2016-03-09T12:15:15+08:00 恒河沙数1 首先感谢你的脚本!
这是我这两天的log内容:
Sat, 05 Mar 2016 07:45:44 +0800
/: 219444977664 bytes were trimmed
Sun, 06 Mar 2016 07:51:26 +0800
/: 3834396672 bytes were trimmed
Mon, 07 Mar 2016 08:08:36 +0800
/: 2750799872 bytes were trimmed
Tue, 08 Mar 2016 07:42:33 +0800
/: 219187560448 bytes were trimmed
Wed, 09 Mar 2016 07:30:04 +0800
/: 2657067008 bytes were trimmed

可以看出除了第一天和倒数第二天trim了220G以外(我的SSD是256G的)其他都是2-4G的级别。通过实验我发现,只要存在重启,重启之后的trim数据就会特别大。请问你出现过这种情况么?是不是我哪里设置的不对?

有本事你咬他们啊?
