标题: 新手求助！挂载盘阵后，盘阵原有文件目录丢失！
服务器OS原来是FB6.1RC，挂接了一台盘阵，盘阵为Raid5，freebsd文件系统，保存有很多资料。最近用6.1 Release对服务器重做了系统，重做系统时在分区步骤里对盘阵选择了mount。系统重新启动后发现，盘阵挂载点下没有任何文件，也无任何目录，df -h发现盘阵已用空间和未做系统前相同，相信原数据仍在盘阵上。

用fcsk对盘阵扫描后一无所获。

上述情况该如何处置？由于数据比较重要，必须找回，我是菜鸟，肯请各位大侠支招，后学不胜感激，并先行谢过！

重做系统时在分区步骤里对盘阵选择了mount

除了mount外,还有没有其他动作?

最好能多贴了信息,如dmesg,/etc/fstab,df -ih.

选择了挂载点，newfs处原来是ufs+n，让我修改成了ufs+y，除此之外再无其他改动。
我现在家里，不在机房，具体的信息如dmesg等，得到单位后才能发上来，可否给我些策略性的指导

晕,nfs y应该就是newfs,即格式化啊.

作者: congli 时间: 2006-08-12 22:07
这里组合有:
ufs+s y
ufs+s n
ufs y
ufs n
swap
记忆一下是那个?

标题: 回复 4楼 congli 的帖子
不过df -h返回的信息中，可以知道已用空间和未做这些时相同，如果格式化了，已用空间不是应该是近乎0吗

作者: bluebrat 时间: 2006-08-12 22:10
不是第一个就是第三个，我记得有y，好像第一个比较更像一些

相信你已经把这个盘阵格式化了.

那么，可由什么途径补救呢？

作者: congli 时间: 2006-08-12 23:15
我也想知道.

作者: bluebrat 时间: 2006-08-12 23:28
我在网上找了半天，请到http://www.stellarinfo.com/bsd-file-recovery.htm
看看Stellar Phoenix BSD这个软件，可惜要不少钱，版主有办法吗？

作者: bluebrat 时间: 2006-08-13 21:11
我在安装了xp和fb的双系统上试了一下3.0，可以在xp下正确读出fb分区上的数据，但是要实际用过才能确定是否能成。
这个软件的老家在http://www.data-recovery-software.net/

作者: bluebrat 时间: 2006-08-14 22:35
这东西还行，可以对付UFS文件系统，只是我扫描500多G的盘阵，扫描的很累。
我用的是R-STUDIO network edition 3.0，注册key是我在网上找的老外弄得，也一起奉献给大家吧。
The Registration Key for R-STUDIO network is:
RAAACbLROc84axeakSB+9D0RVTXcGQ93I2mjd8edfo+E+MljUkp4WRSw2B9udY8TakmxWxgDPboVLa4h4FcG97FHQMHB

作者: bluebrat 时间: 2006-08-17 09:40
弄了几天，让我大失所望。R-Studio恢复的东西只有少部分文档可用，所有软件全部报销。
Stellar Phoenix (BSD)则在扫描过程中死锁。
苦恼中.....
