I had most problems that I had when I still used reiser 2 with Linux 2.2, 
which has long been obsoleted since reiser 3 was first included in the 
mainline kernels since 2.4.1 or something.

All problems occured during bad system crashes, situations which really 
should not happen and which would have caused damages with any file 
system. So Reiser does not "corrupt files randomly", however in my 
experience it's true that the damage caused by Reiserfs can exceed the 
damage done by ext2. So far I had no serious crashes with ext3, so I 
cannot say anything about this fs.

I just also see reiser's advantages over competing filesystems in some 
areas. Dovecots speed improved significantly when I switched my (clearly 
underpowered) mailserver machine from pure ext2 to reiserfs. It had also 
had a few crashes (mainly power outages) since I set it up and I have not 
had any problems with the system or it's reiserfs partition which carries 
the whole /var fs so far.

Greetings,

  Gunter
