What did I do wrong? (Filesystem recovery with ReiserFS)

[James Herschel <jherschel@leasecor.net>]

Hello,

I rebooted my server one day to find that I needed to run reiserfsck.  
So I booted up my trusty copy of Knoppix and ran it.  It said that I 
needed to run --rebuild-tree, so I did.

Problem was that even though all the files were recovered, they were all 
recovered to meaningless directories in lost+found.  I was able to get 
all the important data back, but now I'm wasting my morning getting 
everything set up again.

What should I do next time?

Thanks!
