新手求助！挂载盘阵后，盘阵原有文件目录丢失！

bluebrat

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.

bluebrat

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.

congli

这里组合有:
ufs+s y
ufs+s n
ufs y
ufs n
swap
记忆一下是那个?

bluebrat

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

bluebrat

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
