结论
kimsufi 的独服，硬盘有坏道，要自己重装系统才给换盘。
从收到的邮件的意思看，似乎是kimsufi的独服会自动硬件检测并发现错误，但只要你的机子能转是不会给你换硬盘的。自己处理数据
当你自己点重装系统时如果系统已经检测到故障，会触发人工干预。。。进行全面硬件诊断，如果检测有问题，会自动给换。。。。只开单是不管用的。重启，救援模式啥的也都不管用。。。。。
Interventions干预记录中，可以看到19点27做了硬件诊断
我的ticket依然没动静，但多了一个诊断完成的单子，内容和邮件一致
起因
硬盘好像有坏道了，开了单子俩礼拜也没有人处理，搜了搜kimsufi好像就是没人回单的Kimsufi reviews?，说如果有硬件故障会自动检测到，然后ovh的人会处理，但我这个有坏道的问题，不是挂掉，也没有人处理。
折腾了一圈，以为修复了，结果重装系统时，收到另一个检测到错误要换硬盘的邮件。。。。。

之前折腾的内容整理如下
进入救援模式
管理面板
netboot
rescue
救援模式使用的系统，选"rescue64-pro"。
选好之后点击"Next"，然后点击"Confirm"确认
手动将服务器重启一次，可以使用Kimsufi控制面板上的"Restart"硬重启功能。
接下来可能需要等数分钟，系统会发送一封主题为"Access settings for RESCUE mode"的邮件给你，打开一看，这里面有救援模式系统的root账户密码。
根据邮件就可以登陆进行操作了
救援模式原有的/dev/sda 默认是没有mount的，可以进行硬盘和分区修复操作
修复硬盘坏道
查看眼影盘的smart信息
smartctl -a /dev/sda
197 Current_Pending_Sector 0x0012 100 001 000 Old_age Always - 12
198 Offline_Uncorrectable 0x0010 100 001 000 Old_age Offline - 12修复命令
nohup dd bs=512k if=/dev/zero of=/dev/sda &
修复完毕后在看smart信息
smartctl -a /dev/sda
197 Current_Pending_Sector 0x0012 100 001 000 Old_age Always - 0
198 Offline_Uncorrectable 0x0010 100 001 000 Old_age Offline - 0 变成0了，说是已经修复
如果没有修复，最好换磁盘
也可以屏蔽磁道（没有试）
参考文章 linux系统下检测硬盘上的坏道和坏块
扫描坏块
badblocks -s -v /dev/sda1 > badsectors.txt
标记坏块
fsck -l badsectors.txt /dev/sda1
坑
网上有的文章是可以通过badblocks 输入块号来写入修复，不需要全盘修复。
但badblocks命令无法直接修复大硬盘，坏块编号超过32位整数无法输入。
badblocks only takes 32-bit integer as start/end values
通过kimsufi面板，安装系统。
装的过程很简单，选要装的系统
选定制安装，自定义硬盘分区表
然后下一步，勾上发布版内核即可。
坑，等半天没有反应，也没有装好的用户名密码邮件，看邮箱，有一个好像要换硬盘的邮件。。
