Hello,
I'm trying to do a rebuild-tree for days now, it seams that I've got the same
probleme above. The server didn't hang when the error accured. I've turned on
the monitor on the morning and have seen that the disk got full (was about
120Go free, 650Go total), the root disk is also reiserfs but is ok,
reiserfsck(3.6.19) told me that I need to run reiserfsck with the rebuild-tree
option but it never ended. Only my LVM logical disk is now unmountable.
I am using gentoo, and I've already tried to recompile reiserfsprogs, but
unfortunatly, same result.
Thanks
Vitold

Right, dd seems to produce an output with just skipped bad blocks not writing
anything into the output.

Looks like you built the reiserfsck on another mashine. Could you rebuild it
on the same mashine you run it. It is possible to suppress the logfile with
-n option, but I think the logfile was so big due to this endless loop.
