Re: corruption? how do I fix?

Yury,

Thx for the quick response.  Is there a way to 'see' if the
reiserfsck --fix-fixable .... command would work?  like a dry run? 
Running another backup is going to take a while, so I need to gauge the 
risks.  What is this command going to do?  Is it permanent when I do it 
(seems like it from the docs)
