Hi,
I've been running "reiserfsck --rebuild-tree /dev/hdd" for 24h now on
a 40Gb drive that is 99% full. I am using reiserfsprogs 3.6.2 from
Debian unstable.

The result of reiserfsck --check and the result with --fix-fixable:
bread: Cannot read a block # 10052279.

The --rebuild-sb seemed successful:

Is this ok ? (y/n)[n]: y

Do not forget to run reiserfsck --rebuild-tree


Here's my results so far from the --rebuild-tree session:

=46rom what I can see, this session can last for many years...

Any advise?
