Ext4狂野

Question

我所有的主要硬盘ST3250312AS 7200.12 SATA6GB/S 250 6Gb梭子鱼 (2岁)都要疯狂了。它已于2014年6月28日开始。

分区sda1(root)、sda5(home)、sda7(var)不时地在随机文件中捕捉到这一点。有时它是我的主分区，当我通过浏览器下载一些东西。有时是/var，我的.rrd的基础是：

我已经完成了备份。我不怕。

我在最新的Ubuntu和最新的内核上。

Linux Ubuntu 3.13.0-30-lowlatency #54-Ubuntu SMP PREEMPT Mon Jun 9 23:14:29 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

谷歌在许多不同的论坛上为我找到了许多相似的问题和完美的答案。

我想弄清楚，是硬件故障还是这个补丁 ( 30小时前)到了linux内核。

有什么建议吗？

Edit1:我找到了完美的牙套：

Edit2: smartctl -a /dev/sda -> pastebin.com/VsFEbAAQ

Edit3:为什么我希望这不是一个hw，而是Ext4:因为，阅读这个线程bbs.archlinux.org/viewtopic.php?id=151341

泰德·塞奥，也是那个犯了上一次补丁的人，大约在2012-10-24年间。

Answer 1

恐怕这是一个简单的硬件故障案例。

内核的补丁没有在您的系统上运行，因为您的内核是近一个月前构建的。对于Ubuntu来说，引入一个在任何情况下都不在发布内核中的内核补丁是非常极端的。

如果我看到那些信息，我就会把磁盘换掉。
