Re: Corruption: --fix-fixable results in all nlink values = 0

Hi Vitaly,

Your analysis is dead-on!

I ran reiserfsck a second time, and this time it stopped later.
The strange thing is this disk and installation are relatively new 
(March 2002), and digging back through syslogs shows occurances 
(kernel)(.*)(hda) only on:
4 May 20 (2 sectors)
370 Aug 15 (>100 different sectors involved)
34 Aug 16 (17 sectors)

...which means the problems only really started by all this fsck stuff. 
At least sectors 81170944 - 81171056 seem to be involved during 
yesterday and today. Why would these problems be so recent? The 
filesystem has been up to 95% full at times, and a lot of it is indexed 
with a web indexer daily, one would have expected this earlier, no?

I'll keep you posted if things fare worse (or better, hopefully),

- Gerrit
