Hi

Hello.


I am getting a negative block-number with reiserfsck when doing
--rebuild-tree -S (or without -S). This causes a segmentation fault
later (pass 2) in the check because it tries to read a "non-existant
block". My rebuild takes 3 days and i didn't copy the stdout-info the
first time so I will post some more info as soon as it becomes available.

Pass 0:
####### Pass 0 #######
The whole partition (-710934672 blocks) is to be scanned
Skipping 117586 blocks (super block, journal, bitmaps)


So you do have a ~16T partition. Correct?


 -711052258 blocks


will be read

Does anyone have any idea on how to fix this?

On a 64-bit system.


It looks like you have encountered an overflow/truncation fsck bug specific to giant volumes.

I would first ask Jeff: AFAIK he is planning to enable 16T files
in reiserfs.
Jeff, do you have any non-published fixups for such problems?

Thanks,
Edward.



Sincerely,
