Reiserfs doesn't cope well with crashes....  Under 2.4 I wouldn't 
recommend using it on any kind of critical server - it seems to 
progressively corrupt itself (I'm looking at the second reformat and 
reinstall in a week, and I'm not a happy bunny).

As the warning on reiserfsck says, the rebuild-tree option is a last 
resort.  It's as likely to make the problem worse then improve it (It 
rounds all the file lengths up to a block size, padding with zeros, 
which breaks lots of stuff).  Backup what you can first.

I find that if you run reiserfsck -x /dev/hda1 a couple of dozen times 
it slowly fixes stuff that it couldn't fix on the previous pass.One 
thing that can't fix is the bug that seems to make random files on the 
FS unreadable even for root.The only way I've found around that one is a 
periodic format/reinstall.
